Description
FIELD OF THE INVENTION

Embodiments of the invention relate generally to mobile devices, and more specifically to systems and methods for encrypting mobile device communications.


BACKGROUND OF THE INVENTION

Mobile devices, such as cell phones, personal digital assistants (“PDAs”), smart phones, and other similar devices, have increasingly been utilized to provide additional functionality beyond traditional voice communications. One component of enabling the mobile devices to support these additional functionalities includes installing software applications, such as wallet applications, on the mobile devices. Mobile device applications can facilitate a variety of services performed by or with the mobile devices, including payment applications (e.g., prepaid, credit, debit, etc.), loyalty or incentive applications, transportation payment applications, access control applications, entertainment applications, and the like. Given the sensitive nature of data that may be transmitted or communicated during the provision of a service, such as a payment service, encryption and authentication of information included in mobile device communications and/or the protection of data becomes critical. Because mobile wallet applications are typically stored within a shared or public memory of a mobile device, transaction information generated by a mobile wallet may be more susceptible to breaches in security. Accordingly, improved systems and methods for encrypting mobile device communications are desirable.

DETAILED DESCRIPTION

Various embodiments of the invention are directed to the encryption and/or security of mobile device communications. In certain embodiments of the invention, a mobile device may include both a shared memory space and at least one secure element. A wide variety of applications may be stored within the shared memory space, such as a mobile wallet application. The secure element may include functionality for receiving messages, such as transaction messages, from shared memory applications, encrypting the received messages, and providing the encrypted messages back to the shared memory applications. For example, the secure element may include a security application or an authentication application that receives a message from a mobile wallet. The security application may utilize any number of suitable encryption techniques to encrypt the message, and the secure application may provide the encrypted message back to the mobile wallet. The mobile wallet may then transmit or otherwise communicate the message to a recipient, such as a merchant or a trusted service manager (“TSM”). In a similar manner, the mobile wallet may provide received messages to the security application for decryption. As a result of messages being encrypted and decrypted by the secure element, increased security may be provided for sensitive and/or confidential information.


A wide variety of suitable encryption techniques may be utilized by the secure element and/or secure application as desired in various embodiments of the invention. These encryption techniques include a wide variety of different types of shared secrets between a secure element and a service provider, such as a TSM, and/or a wide variety of key pairs. Examples of suitable shared secrets and/or key techniques include, but are not limited to, user access credentials (e.g., a user name and password) or another basic authentication method, certificate-based authentication, public and private key-based authentication, symmetric key encryption techniques, asymmetric key encryption techniques, dynamic passcode authentication, and/or derived unique key per transaction (“DUKPT”) authentication.


In addition to encrypting a message, in certain embodiments, the secure element may additionally add one or more suitable tags and/or signatures to a message. For example, a message authentication code (“MAC”) or a payload authentication code (“PAC”) may be generated for the message based at least in part upon a shared secret or between the communicating device and the recipient and/or based at least in part upon a key pair. Once generated, the tag or code may be appended to or otherwise associated with a message. Following the transmission or communication of the message, a recipient may identify the tag and evaluate the tag in order to authenticate the message. For example, a recipient may utilize a shared secret and/or key information to decrypt the tag, and the recipient may then analyze the decrypted tag in order to determine whether the tag is valid. If the tag is valid, then the message and/or a mobile device application that generated the message (e.g., a mobile wallet, etc.) may be authenticated.


In certain embodiments of the invention, the security application or another suitable application associated with the secure element may additionally facilitate the establishment of a secure key, such as an asymmetric key, that will be utilized to facilitate subsequent encryption and/or authentication of device messages. For example, both the security application and a TSM may independent generate a symmetric key. A wide variety of suitable information may be utilized to generate or derive a symmetric key, such as secure element and/or mobile device identification information (e.g., card production life cycle (“CPLC”) information associated with the secure element, etc.), and/or information provided by the TSM. In certain embodiments, at least a portion of the information used to derive a symmetric key may be independently identified by each party. For example, the security application may identify CPLC information that was initially stored on the secure element, and the TSM may identify corresponding CPLC information received from a secure element manufacturer.


Once the symmetric keys have been derived, the symmetric keys may be utilized as transport keys for providing an asymmetric key to the mobile device and/or the secure element. For example, a TSM may utilize its symmetric key to encrypt an asymmetric key, and the encrypted asymmetric key may be communicated to the mobile device. The security application may then utilize its symmetric key to decrypt the asymmetric key. Following the decryption of the asymmetric key, the security application may utilize the asymmetric key to encrypt subsequent messages. As a result of using symmetric keys as transport keys, more secure encryption information (e.g., an asymmetric key, etc.) may be securely communicated to the mobile device.


Various embodiments of the invention utilize trusted service management functionality to facilitate integration between multiple service providers and multiple mobile devices operating on any number of carrier networks, each operated by a different mobile network operator (“MNO”). In certain embodiments, a trusted service manager (“TSM”) may be a third party entity strategically positioned to provide mobile device application provisioning services and integration functionality for provisioning mobile device applications and associated end user data (e.g., encryption data, key information, etc.) to end users' mobile devices, to provide mobile device application-related lifecycle management services, to manage the many-to-many relationships between the multiple service providers and the MNOs operating the carrier networks, and/or to authenticate mobile devices during the processing of a wide variety of different requests and/or transactions.


Applications that can be provisioned on mobile devices via a TSM can be any software application provided by a service provider and operable with a mobile device. According to one embodiment, near field communication (“NFC”) applications that enable subsequent transactions using NFC technology of the mobile device (e.g., radio frequency identification (“RFID”)) are among those mobile device applications provided by service providers. However, as used herein, mobile device applications are not limited to NFC-based applications. Example mobile device applications may include, but are not limited to, open loop and closed loop payment applications (e.g., MasterCard® PayPass™, Visa payWave™, American Express® ExpressPay, Discover® ZIP, NXP Mifare®, etc.), transit payment applications, loyalty applications, membership applications, electronic promotion and incentive applications, ticketing applications, access control and security applications, entertainment applications, retail shopping applications, and the like.


In addition to providing integration and mobile device application provisioning functionality, a TSM may be further operable to provide additional features and functionality associated with each application provisioned and with each service provider, MNO, and/or mobile device end user relationship. Example additional features that a TSM may provide include, but are not limited to, application lifecycle management (e.g., load, personalize, lock, unlock, terminate, etc.), secure element lifecycle management (e.g., lock, unlock, terminate, etc.), workflow management (e.g., new handset, exchanged handset, damaged handset, lost handset, stolen handset, closed MNO account, closed service provider account, etc.), secure element data preparation and application personalization, MNO customer service, service provider customer service, over the air (“OTA”) provisioning, secured key management, end user authentication, MNO-based end user registration, carrier network-based end user registration, service provider-based end user registration, interactive voice response-based (“IVR-based”) end user registration, live end user registration, and the like. It is appreciated that the aforementioned additional TSM features and functionality are provided for illustrative purposes only, and that any number of features and functionality may be provided by the TSM to service providers, MNOs, and/or end users in association with the application provisioning services and functionality.

FIG. 2 illustrates an example block diagram 200 illustrating data flow and integration points between the TSM computer 110 and the various other entities that may participate in mobile device application provisioning, integration, authentication, and maintenance, such as multiple service provider computers 160, multiple MNO computers 140, and multiple mobile devices 150, according to one embodiment of the invention. An example operation of the block diagram 200 of FIG. 2 will be described separately and in conjunction with the flow diagrams of FIGS. 3 and 4.


As generally described above, a TSM and associated TSM computer 110 may be operable to load, delete, and manage mobile device applications and associated end user data on mobile devices on behalf of multiple service providers. Additionally, the TSM computer 110 may be operable to facilitate the authentication of mobile devices and/or mobile device communications, as well as the provision of key information to mobile devices. According to various embodiments, the TSM computer 110 may be operable to provide, but is not limited to, one or more of the following functions: to act as a single point of integration between service providers, MNOs, and other TSMs; to load mobile device applications over the air to mobile devices; to accept, prepare and personalize mobile device application end user data; to allow service providers to interact with end users over one or more of the carrier networks for registration and communications; to enable a service provider to authenticate the end user requesting personalization of an application; to manage secured keys (e.g., cryptographic keys, master keys, rotated keys, symmetric keys, asymmetric keys, private keys, transaction specific keys, etc.) used for application provisioning, personalization, and/or authentication of mobile devices; to manage shared secrets for message authentication; to generate and/or validate message tags and/or codes (e.g., MACs, PACs, etc.); to manage mobile device application lifecycles on behalf of service providers over the life of an application; to manage mobile device lifecycles on behalf of MNOs over the life of a handset; and to provide billing and other administration functions to support relationships between MNOs and service providers, and between the TSM and each MNO and service provider.


Various services provided by the TSM computer 110 can be implemented by one or more of the following application modules: the secure element preparation module 126, the lifecycle management module 127, the workflow management module 128, the customer service module 129, the over the air provisioning module 130, the authentication module 131, and the services customization module 132.


The secure element preparation module 126 may be configured to facilitate preparing mobile device secure elements, such as requesting increased space allocated on the secure element for provisioning applications and verifying secure element properties with the MNO. According to various embodiments, the secure element preparation module 126 may further be configured to receive and/or provide personalization data associated with mobile device applications for each end user during provisioning. In one example, a service provider computer 160 may provide personalization data via the service provider gateway 133. As another example, the TSM computer 110 may generate personalization data via the secure element preparation module 126. As yet another example, the TSM computer 110 may coordinate application personalization and/or secure element preparation via one or more third entities.


The lifecycle management module 127 may be configured to facilitate tracking the status of users' mobile devices and the status of previously provisioned applications. For example, the lifecycle management module 127 may be configured to maintain inventories of various types of mobile devices, associated secure elements and the state of the secure elements and applications (active, locked, unlocked, terminated), which may be used to track the status of applications and mobile devices, and to communicate with MNOs and/or service providers regarding the provisioned applications, the mobile devices, the end user, etc. In addition, the lifecycle management module 127 may be configured to coordinate initial application requests, application personalization, secure element preparation, and provisioning; coordinate any third party entities participating in the provisioning process; maintain statuses; and facilitate billing and payment (e.g., MNO fees, service provider payments, etc.).


The workflow management module 128 may be configured to maintain and manage the workflow of events between MNOs and service providers. For example, when the MNO reports a lost or stolen handset to the TSM, the TSM may trigger a series of events to the service providers to prevent fraudulent transactions. In turn, the workflow management module 128, based on service provider rules, may instruct the lifecycle management module to send one or more commands to the mobile device to lock or terminate applications.


The customer service module 129 may be configured to receive and respond to customer service requests, including those from end users, service providers, and/or MNOs. According to one embodiment, the TSM computer 110 and associated customer service module 129 may provide triage and management functions between the various responsible entities (e.g., service providers and MNOs), and/or provide initial or more involved levels of customer service.


The over the air provisioning module 130 may be configured to facilitate the OTA provisioning of mobile device applications and associated end user data with multiple mobile devices. As described in more detail herein, the OTA provisioning module 130 may facilitate communications with third party OTA provisioning providers via the OTA services gateway 135, and/or can facilitate direct provisioning by the TSM computer 110. It is appreciated that, according to some embodiments, the functions of the OTA provisioning module 130 may also be implemented in one or more of the MNO computers 140 and/or within functions implemented by the carrier networks 180a, 180b, either instead of, or in combination with, those provided in the TSM computer via the OTA provisioning module 130.


The authentication module 131 may be configured to provide administration and maintenance functions for shared secrets and/or secured keys (e.g., cryptographic keys, master keys, public keys, private keys, symmetric keys, asymmetric keys, etc.) in accordance with TSM security policies, MNO security policies, and/or service provider security policies. Additionally, the authentication module 131 may be configured to utilize message tags and/or codes to process both outgoing and received communications or messages. Various functions performed by the TSM computer 110 may integrate with the authentication module 131 to provide security for end users, MNOs, and service providers in association with each of the TSM services.


In certain embodiments of the invention, the authentication module 131 may be configured to perform a wide variety of secure key provisioning and/or secure key rotation techniques for various mobile devices 150. For example, following a trigger event (e.g., an initial registration of a mobile device 150 with the TSM, a periodic security update, etc.), the authentication module 131 may drive key information, such as an asymmetric key (e.g., a private key included in an asymmetric key pair, etc.), to the mobile device 150 for storage on and/or use by the secure element. A wide variety of suitable methods and/or techniques may be utilized as desired to provide key information to a mobile device 150.


In certain embodiments, a symmetric key may be utilized to facilitate the provision of additional key information, such as an asymmetric key, to the mobile device 150. For example, both a mobile device 150 and the authentication module 131 may independently generate or derive a symmetric key. A wide variety of different types of information may be utilized as desired to derive a symmetric key. For example, information generated by the TSM and/or information associated with the mobile device 150 and/or secure element may be utilized to derive a symmetric key. In one example embodiment, the TSM may provide TSM information to the mobile device 150, and both the TSM and the mobile device 150 may independent identify mobile device and/or secure element information (e.g., CPLC information, etc.). For example, the mobile device 150 may identify stored CPLC information, and the TSM may identify CPLC information that has been received from a chip manufacturer. The various information may then be combined together and/or processed in a wide variety of different formats and/or utilizing a wide variety of different techniques to derive a symmetric key.


Once the symmetric key has been generated by the authentication module 131, the authentication module 131 may utilize the symmetric key to encrypt additional key information, such as an asymmetric key. The encrypted key information may then be provided to the mobile device 150, and the mobile device 150 may utilize its independent generated symmetric key to decrypt the additional key information. In other words, the symmetric key may be utilized as a transport key to provide more secure key information (e.g., an asymmetric key, etc.) to a mobile device 150. Once the additional key information has been decrypted by the mobile device 150, the additional key information may be stored on the secure element of the mobile device 150 and utilized for subsequent encryption processing. For example, the secure element may utilize a received asymmetric key (e.g., a private key included in an asymmetric key pair) to encrypt subsequent messages output by the mobile device 150, such as messages generated by a mobile wallet application.


One example of the operations that may be performed by the authentication module 131 to facilitate the provision of an asymmetric key to a mobile device is described in greater detail below with reference to FIG. 6.


According to an aspect of the invention, the authentication module 131 may also be configured to process an outbound message or communication in order to add a tag (e.g., a MAC, PAC, etc.) to the communication. In this regard, the communication may be received and validated by a recipient mobile device 150a, 150b. In doing so, the authentication module 131 may identify a recipient mobile device 150a, 150b and determine a shared secret between the TSM computer 110 and the recipient mobile device 150a, 150b or determine other key information to be utilized. A wide variety of shared secrets and/or key information may be utilized as desired in various embodiments of the invention, such as basic authentication, key-based authentication (e.g., public and private key pairs, asymmetric key pairs, etc.), dynamic passcode authentication, certificate-based authentication, and/or DUKPT authentication. Once a shared secret or relevant key information has been identified, the shared secret or key information may be utilized to derive a tag that may be appended or otherwise added to the communication. As desired, one or more payload elements of the communication may be formatted and/or encrypted by the authentication module 131. The communication may then be output for transmission to the recipient mobile device 150a, 150b, and the mobile device 150a, 150b may evaluate the tag in order to determine whether the communication is valid or authenticated. For example, the mobile device 150a, 150b may utilize a shared secret and/or key information to decrypt the tag and determine whether the communication is valid.


In a similar manner, the authentication module 131 may process a communication received from a mobile device 150a, 150b. For example, a mobile device 150a, 150b from which the communication originated may be identified by suitable identifying information associated with the communication (e.g., a device identifier, a telephone number, an Internet Protocol address, a secure element identifier, etc.). Based upon the identification of the mobile device 150a, 150b, a shared secret and/or relevant key information may be identified or determined, and the shared secret and/or key information may be utilized to evaluate a tag associated with the received communication. In this regard, a determination may be made as to whether the tag is valid or authenticated. If the tag is determined to be valid, then the communication may be authenticated, and one or more payload components may be decrypted and/or processed. Otherwise, the communication may be identified as a suspicious communication, and any number of suitable errors and/or exceptions may be generated.


The services customization module 132 may be configured to facilitate customization and selection of services offered by the TSM to each service provider and MNO. As is apparent by that described and illustrated herein, the TSM computer 110 may be configured to provide a variety of features and functions associated with mobile device application provisioning and integration between the service providers and MNOs. Accordingly, due at least in part to the simplified common interfaces and gateways (e.g., MNO gateway 134 and MNO interface 122, service provider gateway 133 and service provider interface 121, etc.), the TSM computer 110 may permit each service provider and MNO to customize from the services available. The services customization module 132 may be configured to include computer-executable program logic to generate an interface for selecting and customizing TSM services, and to coordinate the implementation by other TSM application modules. For example, a first service provider may opt to only provide mobile device applications to mobile devices operating on certain carrier networks, while a second service provider may opt to provide mobile device applications to all mobile devices irrespective of the associated carrier networks. As another example, a service provider may request the TSM computer 110 to provide end user registration functionality on behalf of the service provider, while a second service provider provides its own registration services and integrates via the end user registration gateway 136 and associated end user registration interface 124. Accordingly, the customization module may permit coordinating and implementing the appropriate combination of features and integration points as requested by service providers and MNOs. It is appreciated that any combination of features and integration points may be provided by the TSM computer 110, and that these are provided for illustrative purposes only. In one implementation, the customizations provided may be driven at least in part by contractual relationships between the TSM and respective service providers and MNOs, such that the TSM may also support and/or enforce these contractual agreements as part of the features of the services customization module 132.


The MNOs and associated MNO computers 140 may be operable to provide the communications channel to reach and provision mobile device applications and associated end user data on end users' mobile devices. According to various embodiments, each MNO computer 140 may be operable to provide, but is not limited to, one or more of the following functions: provide the TSM computer with information on mobile device secure elements and unique mobile device identity modules (e.g., Universal Subscriber Identity Modules (“USIMs”)) throughout the lifecycle; provide a communications gateway via a respective carrier network for OTA provisioning of mobile device applications; provide a mobile device user interface for accessing provisioned mobile device applications on each mobile device (e.g., a mobile wallet); facilitate management of secured keys used to securely load and delete mobile device applications on mobile device secure elements; interface with the TSM computer; facilitate authentication of the end user interfacing with the TSM; facilitate allocating memory for mobile device applications on the end users' mobile devices; communicate to the TSM computer that unique end user identity modules have changed; communicate to the TSM computer the status of unique mobile device identity modules (e.g., which USIMs have been lost, stolen, damaged, replaced by new mobile devices, etc.); and facilitate management of any tariffs and fees associated with application provisioning communications.


An MNO gateway 134 and associated MNO interface 122 are operable for providing a common point of integration between the TSM computer 110 and the multiple MNO computers 140. According to one embodiment, the MNO interface 122 is configured to communicate with each MNO according to the same common MNO message standard, as described further herein. Moreover, according to various embodiments, the MNO gateway 134 and associated MNO interface 122 are further operable to permit the TSM computer 110 to communicate with mobile devices 150 via a respective carrier network operated by each MNO.


The service providers and associated service provider computers 160 are operable to provide one or more services in which mobile device end users participate (e.g., financial services, membership services, loyalty account services, etc.). Accordingly, the service providers represent the entities that generate and/or provide mobile device applications associated with these services that are provisioned via the TSM computer 110 on end users' mobile devices. A service provider generating and providing the mobile device applications may be the same service provider that operates the underlying service, or may be a service provider providing the mobile device applications on behalf of another service provider operating the underlying service. According to various embodiments, each service provider computer 160 may be operable to provide, but is not limited to, one or more of the following functions: supply a mobile device application for loading onto the mobile devices of its end users (e.g., customers of the service provider); request the use of and/or provisioning of TSM-created soft-card applications (e.g., electronic application permitting payment or other features that can be used in association with participating service provider transactions); facilitate end user authentication processes and associated information; facilitate the creation and maintenance of end user application accounts (e.g., financial account if the service provider is a financial institution or payment processor, membership or loyalty account if the service provider is a retailer or other merchant, etc.); provide end user support for their provisioned mobile device applications; receive application messages from mobile devices returned via one or more of the carrier networks; facilitate processing contactless transactions associated with the provisioned mobile device applications (e.g., a payment transaction at a retailer, etc.); facilitate management and maintenance of application-related secured keys and share these keys with the TSM computer; and facilitate mobile device application personalization and/or coordinate with TSM to prepare personalization data.


A service provider gateway 133 and associated service provider interface 121 are operable for providing a common point of integration between the TSM computer 110 and the multiple service provider computers 160. According to one embodiment, the service provider interface 121 is configured to communicate with each service provider according to the same common service provider messaging standard, as described further herein.


The mobile devices 150 represent the respective end users that have contractual relationships with the MNOs (e.g., for operating on a respective carrier network) and with the service providers (e.g., for participating in one or more services offered by the service providers). Accordingly, end users may utilize the mobile devices 150 to register for, request, and activate mobile device applications from service providers via the TSM computer 110. According to various embodiments, each mobile device 150 may be operable to provide, but is not limited to, one or more of the following functions: activate mobile devices and/or secure elements with an MNO; register for and request mobile device applications from a service provider (or agent of the service provider) or from an MNO; download mobile device applications and associated end user data on mobile device secure elements; authenticate the respective end user and/or mobile device to the service provider to permit application personalization; activate applications with the respective service providers; generate PACs for association with output communications; evaluate and/or validate received communications; perform transactions using the provisioned mobile device applications (e.g., a payment transaction at a retailer, etc.); initiate customer service requests (e.g., with the respective MNO, with service providers, with the TSM, with other third party entities, etc.); notify the respective MNO of a new mobile device and/or secure element; and alter end user settings associated with provisioned mobile device applications (e.g., change or reset a PIN, cancel a mobile device application, cancel an MNO relationship, etc.).


An OTA services gateway 135 and associated OTA services interface 123 are operable to facilitate provisioning of mobile device applications and associated end user data to end users' mobile devices 150. According to one embodiment, the OTA services gateway 135 may be configured to permit the TSM computer 110 to transact with third party OTA provisioning providers to perform all or some of the OTA provisioning services with mobile devices 150, such as by utilizing a common provisioning messaging standard for all third party OTA provisioning providers in a manner similar to that described with reference to the MNO interface 122 and service provider interface 121. According to another embodiment, the OTA services gateway 135 may be configured to permit the TSM computer 110 to provision mobile device applications and associated end user data directly to the mobile devices 150, such as via one or more carrier networks. According to various embodiments, the MNO gateway 134 and associated MNO interface 122 may be utilized at least in part to provide OTA provisioning by the TSM computer 110, such as for accessing and communicating over a respective MNO carrier network.


An end user registration gateway 136 and associated end user registration interface 124 are operable to facilitate communications with mobile device end users for registering to receive mobile device applications, requesting mobile device applications, updating status on mobile devices 150 and/or provisioned applications, and the like. According to one embodiment, service provider computers 160 and/or MNO computers 140 provide registration applications for end users (e.g., mobile device-based registration interface, Internet-based registration interface, etc.). Thus, the end user registration gateway 136 and associated end user registration interface 124 provide a common integration point and associated common messaging standard for receiving and responding to such requests in a manner similar to that described with reference to the MNO interface 122 and service provider interface 121. According to another embodiment, the TSM computer 110 may be configured to provide similar registration services to mobile device end users, such as may be performed on behalf of the service providers or MNOs. According to various embodiments, the MNO gateway 134 and associated MNO interface 122 may be utilized at least in part to provide end user registration functions by the TSM computer 110, such as for transmitting and receiving registration data over a respective MNO carrier network. According to various embodiments, the service provider gateway 133 and associated service provider interface 121 may be utilized at least in part to provide end user registration functions by the TSM computer 110, such as for end user authentication.


A third party integrator gateway 137 and associated third party integrator interface 125 are operable to facilitate communications with one or more third party integrators, such as may occur when sharing responsibilities or otherwise communicating with other TSMs. Much like that described with reference to the MNO interface 122, MNO gateway 134, service provider interface 121, and service provider gateway 133, the third party integrator gateway 137 and associated third party integrator interface 125 provide a common integration point and associated common messaging standard for communicating with any third party integrators.


With reference to FIG. 3, a flow diagram is provided illustrating an example method 300 for providing a mobile device application by a TSM computer 110, according to one embodiment. The method 300 is described also with reference to the block diagram 200 of FIG. 2.


By example only, the steps illustrated and described with reference to FIG. 3 can be performed to facilitate the provisioning of any mobile device application, such as an application that facilitates the encryption of messages and/or communications and/or a near field communication (“NFC”) payment application provided by a payment service provider (e.g., card account issuer, financial institution, etc.). A mobile device user would request the installation of a desired application on an associated mobile device from either the TSM or directly from a service provider providing the NFC payment application. The request ultimately would be transmitted to the TSM, such as via the end user registration gateway 136 and end user registration interface 124 if coming directly from the end user, or via the service provider gateway 133 and the service provider interface 121 if coming via a service provider. Upon receiving the request, the TSM computer then may verify whether the end user's mobile device is capable of receiving installs, whether a secure element associated with the end user's mobile device is adequately configured (e.g., can support an install, sufficient space, etc.). The TSM computer may then perform the necessary steps to prepare the end user's mobile device and associated secure element, either directly and/or via the end user's mobile network operator. In addition, the TSM may perform the various authentication measures to verify the end user, the end user's mobile device, and set up and personalize the requested application for installation on the end user's secure element. After the requested application is personalized and authentication and security measures are in place at the TSM computer, the application may be provisioned to the end user's mobile device, such as via the OTA services gateway 135 and the OTA services interface 123 and/or via the MNO gateway 134 and the MNO interface 122 for interfacing with the end user's mobile network operator. After provisioning, the lifecycle of the application for that end user may be managed via the TSM computer, such as via the lifecycle management application 127. Various services can be provided and/or otherwise facilitated by the TSM computer, such as handling service requests from the end user, the MNO, and the service provider; coordinating billing between the MNO and the service provider; facilitating updates to the application; and any other communications that may be required between the MNO, the service provider, the end user's mobile device, and/or the end user. It is appreciated that this description of provisioning and servicing an application is provided for illustrative purposes, and the methods described with reference to FIG. 3 may be performed for any type of mobile device application between any of a number of parties.


The method 300 may begin at block 305, in which the TSM computer receives a request to provision a mobile device application on a mobile device. According to various embodiments, a provisioning request may come from any of the mobile devices 150 or associated end users, service provider computers 160, MNO computers 140, or associated websites or other network-routed requests. For example, a mobile device end user may transmit a registration request for a certain mobile device application as part of an end user communication 202, whereby the request is received via the end user registration gateway 136. In another example, a service provider registration request 204 is transmitted from a service provider to the end user registration gateway 136 according to a common service provider messaging standard, such as may occur when an end user requests an application via a service provider or when a new application version of a previously provisioned application is available. In yet another example, an MNO registration request 206 is transmitted from the MNO computer 140 to the end user registration gateway 136 according to a common MNO messaging standard, such as may occur if an MNO provides application registration and requests features on behalf of one or more service providers.


Following block 305, operations may continue at block 310. At decision block 310, a determination may be made as to whether the mobile device 150 is capable and/or is permitted to receive an OTA provisioned application. For example, it may be determined whether the mobile device is technically capable of receiving an OTA provisioned application or capable of operating the specific application requested, whether enough memory is available, etc., which may be obtained from the MNO computer 140 via the MNO gateway 134 utilizing MNO communications 208. In another example, it may be determined whether the mobile device and end user are permitted to receive the application requested, such as whether the end user's contract with the MNO or the service provider permits installation and/or use of the application, which may be obtained from the MNO computer 140 by MNO communications 208 sent via the MNO gateway 134 or from the service provider computer 160 by service provider communications 210 sent via the service provider gateway 133, respectively. It is appreciated that any other factor may be considered when determining whether the mobile device can receive the application at decision block 310, as may be desired.


If it is determined at block 310 that the mobile device cannot receive the mobile device application requested, then the method 300 may end. According to various embodiments, the TSM computer 110 may be configured to transmit a failure or status update to the mobile device, end user, MNO, service provider, and/or any other entity or individual. If, however, it is determined at block 310 that the mobile device may receive the mobile device application requested, then operations may continue at block 315.


At block 315, the TSM computer 110 may perform authentication processing of the end user and/or the end user's mobile device. For example, the identity of the mobile device end user may be verified as the correct end user for receiving the mobile device application and/or associated personalization data, and/or that the mobile device is in the correct end user's possession. According to one embodiment, the TSM computer 110 is operable to at least partially perform end user authentication, such as by receiving end user authentication data as part of an end user communication 202 and processing the end user authentication data against service provider provided authentication data and/or TSM stored authentication data. However, according to other embodiments, the respective service provider can authenticate customers directly via the service provider computer 160. According to yet another embodiment, a combination of the TSM computer 110 and the service provider computer 160 may perform end user authentication, such as by receiving authentication data as part of the end user communication data 202 directly via the end user registration gateway 136, processing the authentication data in part by the TSM computer 110, and communicating authentication data and responses with the service provider computer 160 by the service provider communications 210 sent via the service provider gateway 133, according to the common service provider messaging standard. If it is determined that the end user is not authenticated, then the method 300 may terminate, or may re-attempt authentication.


If the end user is authenticated at block 315, then block 320 follows. At block 320, the end user and/or the mobile device is registered with the TSM, because it was previously determined at block 310 that the mobile device and/or the user has not yet received an application via the TSM. According to various embodiments, as part of the registration process, the TSM computer 110 may be configured to store unique identifiers of the mobile device, its secure element, and/or the end users for subsequent processing. For example, according to one embodiment, the TSM computer 110 may store a Mobile Subscriber Integrated Services Digital Network Number (“MSISDN”), Integrated Circuit Card ID (“ICCID”), an International Mobile Subscriber Identity (“IMSI”), and/or card production life cycle (“CPLC”) information to uniquely identify the end user and associated mobile device. According to other embodiments, however, any unique identifier may be used, such as may be provided by the end user or by the MNO.


Following block 320 is block 325, in which the TSM computer 110 facilitates the management of the application space on the mobile device secure element or other memory device associated with the mobile device. As part of this process, additional space may be provisioned via the MNO, secured keys may be provided (e.g., by the TSM or by the MNO), privileges associated with the secure element (or other memory device) may be added or changed, and/or the mobile device may be initialized for utilizing the mobile device application (e.g., initialized for NFC transactions, etc.). It is appreciated that various other steps may be performed as part of preparing the secure element for provisioning the requested application. According to various embodiments, some or all of these steps are initiated by the TSM computer 110 but performed at least in part by an MNO computer 140 communicating directly with the mobile device (e.g., via wireless communications over the respective carrier network, via Internet-based communications, etc.). Though, according to other embodiments, the TSM computer 110 and the associated secure element preparation module 126 and/or OTA provisioning module 130 are operable to facilitate preparing and managing the application space on the mobile device secure element at block 325 via OTA communications 212 from the TSM computer 110 to the mobile device 150 via the OTA services gateway 135 (which, according to various embodiments, may also utilize the MNO gateway 134).


Following block 325 is decision block 330, in which a determination may be made as to whether the mobile device and/or end user associated with the mobile device has previously received a mobile device application via the TSM computer 110. If the TSM computer 110 has previously provisioned an application on the mobile device, then it may be assumed that the end user and/or mobile device is registered with the TSM, has TSM administration software installed, and is capable of OTA application installations. However, if the mobile device has not yet participated in OTA provisioning via the TSM computer, then additional steps may be performed to validate the capabilities and permissions to receive the application. If it is determined at block 330 that the mobile device and/or the end user has previously received a mobile device application via the TSM computer, then operations may continue at block 340 described below.


If, however, it is determined at block 330 that the mobile device and/or the end user has not previously received a mobile device application via the TSM computer, then operations may continue at block 335, and the TSM computer 110 may install TSM administration software on the mobile device 150 that may be utilized to provide secured access to secure elements and further facilitate installing, accessing, and operating TSM-provisioned applications. The TSM computer 110 may install the TSM administration software on the mobile device also by OTA communications 212 sent via the OTA services gateway 135. It is appreciated that, according to another embodiment, a third party OTA provisioning provider may perform some or all of the application installation functions. In another embodiment, the MNO may generate and/or provide TSM administration software capable of accessing and operating TSM-provisioned applications. In one embodiment, the TSM administration software may be utilized to install, access, and operate all mobile device applications provided by all service providers. Though, in another embodiment, multiple administration software applications may be required, such as may occur when certain service provider applications require specialized administration software.


Following block 335 is block 340, in which the requested application may be installed on the secure element (or other memory device) of the mobile device 150. According to one embodiment, the requested application is installed by the TSM computer 110 by communicating directly with the mobile device via the OTA services interface 123 by transmitting application data in the OTA messaging according to the standard required by the specific secure element, mobile device, and/or carrier network technology, such as via Wireless Application Protocol (“WAP”), Short Messaging Service (“SMS”), Multimedia Messaging Service (“MMS”), etc. It is appreciated that, while each of the gateways and associated interfaces described herein are designed to promote a common integration point and common messaging standards to simplify integration and system flexibility, various mobile devices and carrier networks may operate according to a number of wireless technologies, each of which may cause application provisioning processing to be performed differently according to each of the various wireless network technologies. According to another embodiment, however, instead of the TSM computer 110 provisioning the requested application, a third party OTA provisioning provider may perform some or all of the application installation functions. According to this embodiment, the OTA services gateway 135 and associated OTA services interface 123 can be configured to implement a common provisioning messaging standard for communicating with each of the possible third party OTA provisioning providers.


Following block 340 is block 345, in which personalization data associated with the requested mobile device application may be prepared and transmitted to the mobile device. According to one embodiment, personalization data may be generated by the TSM computer 110 from data supplied by the service provider computer 160 via service provider communications 210 in the common service provider messaging format. According to other embodiments, personalization data may be created by the TSM computer 110 based on stored data, or created by a third party entity for providing personalization data. The format and content of personalization data can vary, depending on the mobile device application to be provisioned. Moreover, it is further appreciated that, according to another embodiment, the personalization application data or other associated end user data can be transmitted at or near the same time as the application is provisioned on the mobile device at block 340.


Following block 345 is block 350, in which the TSM computer 110 is operable to manage the provisioned application during its lifetime as installed on the secure element associated with the mobile device 150. For example, as an application is installed at block 340, the TSM computer 110 may be operable to record application installation status, including successes and failures, as may be provided by the lifecycle management module 127. The TSM computer 110 and associated lifecycle management module 127 may thus be configured to track statuses associated with the provisioned application, such as may be utilized to respond to various service provider or MNO requests, to provide periodic updates to service providers and/or MNOs, or to facilitate billing and payment functions. Application status messages can be transmitted as MNO communications 208 via the MNO gateway 134 and/or as service provider communications 210 via the service provider gateway 133, each according to the common MNO and service provider messaging standards, respectively.


In one example, in response to a request from a service provider computer 160 regarding a specific end user (e.g., as identified by name, account, or other unique identifier), the TSM computer 110 is operable to identify the end user as having a TSM-provisioned application installed. The TSM computer 110 may identify the end user by a secure element identifier (e.g., the ICCID, IMSI, etc. associated with the secure element). The mobile phone number (i.e., MSISDN) may be used as a secondary identifier of the end user. Upon identifying the end user, the TSM computer may perform one or more of, but not be limited to, the following functions when managing the application lifecycle: check the application state on an end user mobile device and/or secure element; update an application version on an end user mobile device and/or secure element; lock or unlock an application on an end user mobile device or secure element; remove an application from an end user mobile device or secure element; process a request indicating that the mobile device and/or secure element is lost or stolen; update a customer phone number and mobile device; update a secure element identity (e.g., ICCID); update an end user's authentication data; process an MNO subscriber cancellation; process a service provider end user cancellation; process application service messages; send an end user and/or mobile device MNO or service provider messages; or lock or unlock one or more of the provisioned applications.


The method 300 may end after block 350, having facilitated the provisioning of mobile device applications and integrating multiple service providers with multiple MNOs and their registered mobile devices, by providing a trusted service manager that promotes simplified integration via common gateways and interfaces implementing common messaging standards.


In certain embodiments of the invention, an authentication application or a security application may be stored on a secure element of a mobile device.

For example, the authentication application may receive messages from other applications, such at the mobile wallet, and the authentication application may encrypt outgoing message and/or decrypt incoming messages. The results may then be provided to the other applications for additional processing. In certain embodiments, an authentication application may be initially installed on a mobile device secure element. In other embodiment, the authentication application may be provisioned to the mobile device secure element by a TSM. FIG. 4 illustrates a flow diagram of an example method 400 for providing an authentication application, such as an application that facilitates encryption and/or decryption, to a mobile device, according to an example embodiment of the invention. The method 400 may be performed by a suitable trusted service management system, such as the system 100 illustrated in FIG. 1. The method 400 may begin at block 405.


At block 405, a user may activate a mobile device, such as one of the mobile devices 150 illustrated in FIG. 1. In certain embodiments, the activation of the mobile device 150 may be an initial activation of the mobile device 150. In other embodiments, the activation of the mobile device 150 may be an activation following a software update to the mobile device 150 by an MNO, such as the MNO computer 140 illustrated in FIG. 1. Based upon an activation of the mobile device 150, the mobile device 150 may attempt to establish contact with a TSM computer, such as the TSM computer 110 illustrated in FIG. 1. In this regard, a secure element associated with the mobile device 150 may be provisioned and/or personalized.


At block 410, an authentication provisioning request may be generated by the mobile device 150 and output for communication to the TSM computer 110. For example, a request for the provisioning of an authentication application may be generated and output. In certain embodiments, the request may be generated during an enrollment process of the mobile device 150 with the TSM computer 110. In other embodiments, the request may be generated during a setup process for the secure element.


The request may be received by the TSM computer 110 at block 415. As desired in various embodiments, any number of suitable networks and/or communications techniques may be utilized to facilitate the communication of the request to the TSM computer 110. For example, the request may be communicated via a suitable carrier network, such as one of the carrier networks 180 illustrated in FIG. 1. In certain embodiments, the request may be communicated directly to the TSM computer 110. In other embodiments, the request may be communicated through any number of intermediary systems and/or devices, such as an MNO computer 140. In certain embodiments, a secure communications channel may be established between the mobile device 150 and the TSM computer 110 either prior to the communication of the authentication provisioning request or as a result of the communication.


At block 420, which may be optional in certain embodiments of the invention, the TSM computer 110 may generate a request for various identification information associated with the mobile device 150 and/or the secure element, such as CPLC information and/or secure element identification information, and the generated request may be communicated to the mobile device 150. A wide variety of different types of identifying information may be requested as desired in various embodiments of the invention. At block 425, the request for identifying information may be received and processed by the mobile device 150. The requested information may then be communicated by the mobile device 150 to the TSM computer 110 at block 430, and the TSM computer 110 may receive the requested information at block 435. As an alternative to the TSM computer 110 requesting identifying information, various identifying information may be included in the initial authentication provisioning request. Additionally, in certain embodiments of the invention, a secure communications channel may be established between the mobile device 150 and the TSM computer 110 prior to the communication of identifying information to the TSM computer 110.


As desired, the TSM computer 110 may perform any number of suitable authentication procedures utilizing the identifying information. For example, as explained in greater detail above with reference to FIG. 3, the TSM computer 110 may determine whether the mobile device 150 is a valid device that is capable of and/or that is authorized to receive an authentication application. In certain embodiments, the TSM computer 110 may verify identifying information against information received from a device manufacturer and/or an MNO computer 140. In the event that the TSM computer 110 determines that the mobile device 150 is not capable of and/or not authorized to receive an authentication application, the TSM computer 110 may communicate an appropriate error message to the mobile device 150. Otherwise, operations may continue at block 440.


At block 440, which may be optional in certain embodiments of the invention, the TSM computer 110 may generate, identify, and/or determine a shared secret and/or key information to be utilized between the TSM computer 110 and the mobile device 150 (and/or the secure element). In other words, the TSM computer 110 may identify an authentication proceeding or an initial authentication proceeding that may be utilized by the TSM computer 110 and/or the mobile device 150 to encrypt and/or decrypt communications. A wide variety of different types of authentication proceedings may be utilized as desired in various embodiments of the invention. For example, basic authentication information, such as user access credentials (e.g., a user name and password, etc.), may be identified. As another example, a certificate-based authentication (e.g., a digital certificate, etc.), such as a certificate-based authentication that utilizes a private-public key pair, may be identified. As yet another example, token-based authentication, such as a two-factor authentication system in which tokens are independently generated for each communication (e.g., DUKPT authentication, etc.), may be identified.


At block 445, the TSM computer 110 may request an MNO computer 140 associated with the mobile device 150 to activate or wake up an OTA proxy or OTA proxy application associated with the mobile device 150. For example, the MNO computer 140 may be requested to wake up an OTA proxy that is stored on a general or shared memory or general operation chip associated with the mobile device 150. The OTA proxy activation request may be received by the MNO computer 140 at block 450, and the MNO computer 140 may communicate an appropriate OTA proxy wake up request to the mobile device 150. The OTA proxy wake up request may be received by the mobile device 150 at block 455, and a suitable OTA application associated with the mobile device 150 may communicate an OTA proxy message to the TSM computer 110 at block 460. The OTA proxy message may be received by the TSM computer 110 at block 465, and an OTA communications session may be established between the mobile device 150 and the TSM computer 110.


At block 470, an authentication application and information associated with authentication information, such as key information and/or information utilized to derive key information (e.g., a base level key, etc.) may be driven to the mobile device 150 by the TSM computer 110. In other words, the mobile device 150 may be provisioned with the authentication application. Additionally, as desired, at least a portion of the received identifying information may be stored for subsequent access by the TSM computer 110 during authentication processing.


The authentication application and the authentication information may be received by the mobile device 150 at block 475. In certain embodiments, the authentication application may be stored on or provisioned to a secure element associated with the mobile device 150. For example, a general purpose chip associated with the mobile device 150 may receive the authentication application via an established OTA session, and the general purpose chip may provide the received authentication application to the secure element. Once provisioned, the authentication application and the authentication information may be utilized to encrypt outgoing messages and/or decrypt incoming messages. Additionally, the authentication application may be utilized to generate and/or evaluate message tags and/or codes.


The method 400 may end following block 475.


In certain embodiments of the invention, a secure element associated with a mobile device may facilitate the encryption and/or decryption of messages on behalf of other mobile device applications, such as a mobile device application (e.g., a mobile wallet application, etc.) stored on a shared memory of the mobile device. FIG. 5 illustrates a flow diagram of an example method 500 for encrypting mobile device information, according to an example embodiment of the invention. The method 500 may be performed by a suitable mobile device that includes a first application and/or a secure element. For example, the method 500 may be performed by one of the mobile devices 150a, 150b and associated mobile wallet 156a, 156b and secure element 155a, 155b illustrated in FIG. 1. The method 500 may begin at block 505.


At block 505, a message may be generated by a mobile device application, such as a mobile wallet application 156. As desired, the message may include a wide variety of information, such as transaction information and/or information associated with an intended recipient. Once the message has been generated, operations may continue at block 510, and the mobile wallet 156 may provide the generated message to an authentication application or security application stored on a secure element of the mobile device 150. As desired, the mobile wallet 156 may additionally provide a request to encrypt the generated message to the authentication application.


The authentication application may receive the message from the mobile wallet 156 at block 515. At block 520, which may be optional in certain embodiments of the invention, the authentication application may identify the intended recipient for the message. For example, the TSM or another intended recipient may be identified. In other embodiments, it may be assumed that a common recipient will ultimately receive all messages processed by the authentication application, and no identification will be performed. At block 525, an encryption technique and/or encryption method may be identified for use with the message. In certain embodiments, the identity of the intended recipient may be utilized to determine an encryption technique. For example, a shared secret and/or encryption key information may be identified based upon the identity of the intended recipient.


At block 530, the message may be encrypted by the authentication application. As set forth above, a wide variety of different encryption techniques may be utilized as desired to encrypt the message. For example, a symmetric key, an asymmetric key, or a dynamic unique key per transaction key may be utilized to encrypt the message. As a result of the encryption, the security associated with the message may be enhanced. Additionally, because the encryption is performed by the secure element, the danger of a security breach or a security attack by another application having access to the shared memory of the mobile device may be reduced. At block 535, which may be optional in certain embodiments of the invention, one or more tags may be added to, appended to, or otherwise associated with the message. For example, a MAC or PAC may be appended to the message to facilitate message validation by the intended recipient. The message may then be returned to the mobile wallet 156 at block 540. The mobile wallet 156 may receive the encrypted message at block 545, and the mobile wallet 156 may direct communication of the encrypted message to the intended recipient at block 550.


The method 500 may end following block 550.


In certain embodiments of the invention, a symmetric key pair may be utilized as a transport key pair in order to provision additional authentication information to a mobile device. For example, a symmetric key pair may be utilized to provision an asymmetric key to a mobile device. FIG. 6 illustrates a flow diagram of an example method 600 for establishing a mobile device key, according to an example embodiment of the invention. The method 600 may be performed by a suitable TSM system, such as the system 100 illustrated in FIG. 1. The method 600 may begin at block 600.


At block 605, a mobile device, such as one of the mobile devices 150 illustrated in FIG. 1, may request the establishment of a communications session (e.g., a secured communications session, etc.) with a TSM, such as the TSM 110 illustrated in FIG. 1. The TSM 110 may then establish the communications session at block 610. As desired, a wide variety of different authentication procedures and/or validations may be performed in order to establish a secure authentication session.


At block 615, which may be optional in certain embodiments of the invention, TSM symmetric key derivation information may be identified. In other words, information generated by and/or associated with the TSM that will be utilized to derive a symmetric key may be identified. A wide variety of different types of TSM symmetric key derivation information may be identified as desired in various embodiments of the invention. Once the TSM symmetric key derivation information has been identified, the information may be transmitted or otherwise communicated to the mobile device 150 at block 620. Along with the TSM symmetric key derivation information, a formula and/or instructions for deriving a symmetric key may be communicated to the mobile device 150. The TSM symmetric key derivation information and/or symmetric key derivation instructions may be received by the mobile device at block 645, which will be described in greater detail below.


At block 625, the TSM 110 may access stored information associated with the mobile device 150 and/or the secure element. For example, secure element information (e.g., CPLC data, etc.) obtained from a manufacturer of the secure element may be identified. At block 630, the TSM 110 may utilize the secure element information to derive or generate a symmetric key. As desired, at least a portion of the TSM symmetric key derivation information may also be utilized in the derivation of the symmetric key. For example, TSM key derivation information may be combined with the secure element information, and the resulting combination may be utilized to derive a symmetric key. The derived symmetric key may then be utilized at block 635 to encrypt an asymmetric key (or other key information) to be transmitted to the mobile device 635. In other words, the derived symmetric key may be utilized as a transport key for communicating more secure key information to the mobile device. Once the asymmetric key has been encrypted at block 635, operations may continue at block 640, and the encrypted asymmetric key may be communicated to the mobile device 150.


As set forth above, the TSM symmetric key derivation information and/or key derivation instructions may be received by the mobile device 150 at block 645 and provided to the secure element. At block 650, the secure element may identify mobile device 150 and/or secure element information, such as CPLC data. The information identified by the secure element may be the same information that is independent identified by the TSM 110 at block 625. At block 655, the secure element may derive a symmetric key in a similar manner as that utilized by the TSM 110. According to an aspect of the invention, the two symmetric keys may be independently derived. In this regard, the symmetric key will not be transmitted between the TSM 110 and the mobile device 150, thereby reducing the risk of interception and/or skimming attacks.


At block 660, the encrypted asymmetric key may be received by the mobile device 150 and provided to the secure element. At block 665, the secure element may utilize the symmetric key derived by the secure element in order to decrypt the asymmetric key. The decrypted asymmetric key may then be established by the secure element at block 670 as a key to be utilized in conjunction with subsequent messages. For example, the asymmetric key may be a private key of an asymmetric key pair that will be utilized to decrypt subsequent messages output by the mobile device 150, such as messages generated by the mobile wallet and/or other mobile device applications.


The method 600 may end following block 670.
