Description

BACKGROUND

Blockchain is emerging as a preeminent decentralized ledger and is receiving increasing attention from researchers, practitioners, organizations, and the public. Initially, blockchain was developed to address the “double spending” problem in cryptocurrencies, but recently, many new applications of blockchain have been proposed or are being developed. Blockchain allows sharing data in a decentralized, transparent and immutable way, using a peer-to-peer network, without the need to trust any particular entity.

Blockchain is receiving growing attention not just as the underlying technology of cryptocurrencies, but also as a public ledger in various domains. Financial institutions, for example, are examining the use of blockchain as a ledger for financial transactions to cut out the middleman to reduce costs and to expedite processing transactions. Blockchain also can be used to maintain digital assets, such as stocks, bonds, land titles, and the like. Stored transactions record the transfer of assets between users. Blockchain can store data and documents, either in full or merely a digest of the data (e.g., a cryptographic hash like SHA-256) to provide evidence of the existence of data or documents, such as contracts, patents, scientific publications, deeds, insurance policies, and the like. Blockchain also can be used for identity management through hashed features of a person (e.g., verifiable attributes of the person) stored with a public key or some other means to electronically sign documents, or access remote services to protect people from identity theft and fraudulent impersonation. Blockchain has the potential to provide a secure infrastructure for smart cities and could facilitate the creation of a marketplace of social data where people share their private data for public benefit. Blockchain also has commercial uses, such as for tracking diamonds from mines to market, managing data provenance in Internet of Things (“IoT”) systems, providing transparency in product manufacturing and supply chain management, and supporting vehicle provenance.

SUMMARY

Concepts and technologies disclosed herein are directed to security management of devices using blockchain technology. According to one aspect disclosed herein, a smart contract for a device can be created. The smart contract can identify a plurality of parties including a device customer, a device manufacturer, and a vulnerability assessor. The smart contract can include an expected action to be performed by the device manufacturer responsive to a trigger event. In response to the trigger event being detected, the smart contract can be executed to cause the expected action to be performed by the device manufacturer.

In some embodiments, the trigger event can include a discovery of a security vulnerability of the device. The discovery of the security vulnerability of the device is made by the device customer, a service provider, or some other entity and made available by a vulnerability assessor. In these embodiments, the expected action can include a remediation of the security vulnerability. The security vulnerability can involve a software application of the device. The security vulnerability can involve an operating system of the device. The security vulnerability can involve a firmware of the device.

In some embodiments, the trigger event can include an availability of an update for the device. The update for the device can include a software application update, an operating system update, a firmware update, and/or a hardware update. In some other embodiments, the trigger event can include the device reaching an expected end-of-life.

It should be appreciated that the above-described subject matter may be implemented as a computer-controlled apparatus, a computer process, a computing system, or as an article of manufacture such as a computer-readable storage medium. These and various other features will be apparent from a reading of the following Detailed Description and a review of the associated drawings.

DETAILED DESCRIPTION

Many devices are brought to market in a rush to take advantage of the latest technological innovation and beat competition without proper security in place. There is a need for a secure, trusted solution to device lifecycle management from the moment a device is manufactured until the device reaches end-of-life. In general, Internet-connected devices require frequent updates to address newly-discovered vulnerabilities and/or to support new capabilities introduced by the manufacturer. However, in many cases, these updates are not performed, and the devices are left to function with vulnerabilities open to be exploited. Moreover, in many cases, the updates are not automatically triggered by any process and devices continue to be vulnerable until compromised, a device user triggers the updates, or the device reaches end-of-life. The concepts and technologies disclosed herein address the problem of device security accountability and propose an automatic method to establish the realization of security accountability via smart contracts between the device manufacturer and the device user, recorded in a distributed ledger, public (e.g., Ethereum) or private, using blockchain technology.

While the subject matter described herein may be presented, at times, in the general context of program modules that execute in conjunction with the execution of an operating system and application programs on a computer system, those skilled in the art will recognize that other implementations may be performed in combination with other types of program modules. Generally, program modules include routines, programs, components, data structures, computer-executable instructions, and/or other types of structures that perform particular tasks or implement particular abstract data types. Moreover, those skilled in the art will appreciate that the subject matter described herein may be practiced with other computer systems, including hand-held devices, mobile devices, wireless devices, multiprocessor systems, distributed computing systems, microprocessor-based or programmable consumer electronics, minicomputers, mainframe computers, routers, switches, other computing devices described herein, and the like.

In the following detailed description, references are made to the accompanying drawings that form a part hereof, and in which are shown by way of illustration specific embodiments or examples. Referring now to the drawings, in which like numerals represent like elements throughout the several figures, aspects of concepts and technologies for security management of devices using blockchain technology will be described.

Turning now to FIG. 1, an operating environment 100 capable of implementing aspects of the concepts and technologies disclosed herein will be described. The operating environment 100 includes a smart contract 102 recorded on a blockchain 104 of which a plurality of computing systems 106A-106N (also referred to herein in the singular as a computing system 106 or in the plural as computing systems 106) are a part. The smart contract 102 defines obligations of an agreement among two or more parties and automatically enforces those obligations. Those skilled in the art will appreciate the smart contract 102 otherwise known as a self-executing contract, a blockchain contract, or a digital contract. The smart contract 102 includes computer code that is stored and replicated on the blockchain 104 and is supervised by the plurality of computing systems 106A-106N that run on the blockchain 104. The blockchain 104 is a digitized, decentralized, distributed ledger of transactions. In some embodiments, the blockchain 104 operates on a public blockchain-based computing platform, such as Ethereum, for example. In other embodiments, the blockchain operates on a private blockchain-based computing platform.

The operating environment 100 also includes a device 108 manufactured by a device manufacturer 110 and sold to a device customer 112. The device manufacturer 110 and the device customer 112 can be parties identified in the smart contract 102. In addition, a vulnerability assessor 114 can be identified as another party in the smart contract 102.

The smart contract 102 can include code that defines one or more expected actions to be performed by the device manufacturer 110 responsive to a trigger event, such as, for example, a trigger event of when the device 108 is sold, a trigger event of when a vulnerability is discovered, a trigger event of when an update is available, a trigger event of when a new feature is available, a trigger event of when an expected end-of-life is reached, or some other event trigger, and can automatically enforce one or more expected actions to be performed within a specified time frame. For example, if a security vulnerability is discovered and is not addressed by the device manufacturer 110 within 24 hours, then the device customer 112 (and/or a device owner if distinct) can be reimbursed monetarily or in some other way (e.g., free service or discounted service) in accordance with one or more obligations defined in the smart contract 102.

The device 108 is any device that includes hardware 116, firmware 118, and/or software 120. By way of example, and not limitation, the device 108 can be a router, switch, hub, modem, bridge, repeater, smartphone, tablet, consumer electronic device, Internet of Things (“IoT”) device, personal computer, server computer, video game console, still camera, video camera, audio recording device, Global Positioning System (“GPS”) device, personal data assistant (“PDA”), electronic reading device, smart watch, smart speaker, appliance, smart home device, home security device, vehicle entertainment device (also known as “infotainment”), vehicle electronic control unit (“ECU”), vehicle navigation system, any other networking device, any other end user device, any other enterprise device, combinations thereof, and the like.

The hardware 116 includes any physical component of the device 108. An individual hardware 116 component might include its own firmware 118 and/or software 120 that can be addressed by the smart contract 102 separate from other components. For example, a communications component, such as a cellular radio, might include firmware that can be updated separately from other firmware 118 and/or software 120 associated with the device 108. The firmware 118 can be software code that is embedded in the hardware 116 or some individual component thereof. The software 120 can include operating systems and software applications executable by the hardware 116.

The hardware 116, the firmware 118, and/or the software 120 can be subject to one or more security vulnerabilities during its lifecycle. The smart contract 102 can specify specific security vulnerabilities, categories of security vulnerabilities, or other specifications related to one or more security vulnerabilities the device 108 might encounter during its lifecycle. The smart contract 102 can include one or more expected actions to be performed by the device manufacturer 110 responsive to the discovery of one or more security vulnerabilities. For example, an expected action might include a remediation of a security vulnerability via an update to the hardware 116, the firmware 118, and/or the software 120. An update to the hardware 116 might require the device 108 to be returned to the device manufacturer 110 for the update, user-serviced in accordance with instructions provided, at least in part, by the device manufacturer 110, or serviced by a third party designated by the device manufacturer 110, for example. It is contemplated that the smart contact 102 can include obligations to address manufacture defects and/or other warranty-related issues. Additionally or alternatively, the smart contract 102 might include obligations to address damage to the device 108 or some component thereof.

Security vulnerabilities can be monitored by the vulnerability assessor 114. The vulnerability assessor 114 is a third party to the device manufacturer 110 and the device customer 112. Security vulnerabilities can also be discovered by the device customer 112, one or more users of the device 108, or reported by a third party, such as a researcher, vulnerability discloser, and/or information technology vendor. In any case, the entity that discovers and/or reports a security vulnerability can do so in accordance with a vulnerability assessment protocol. The smart contract 102 can specify a vulnerability assessment protocol. The smart contract 102 can publish a security vulnerability via the vulnerability assessor 114. In some embodiments, the vulnerability assessor 114 can be or can include a system such as a common vulnerability and exposures (“CVE”) system.

The operating environment 100 also illustrates operations 122-134 that can be performed to implement the smart contract 102. At operations 122, 124, the device customer 112 can buy the device 108, and the device manufacturer 110 can sell the device 108 in accordance with the smart contract 102. The device customer 112 might be a business, an end user, or a reseller, and the obligations in the smart contract 102 can reflect any hierarchy that might exist. At operation 126, the device manufacturer 110 can ship the device 108 to the device customer 112 per the smart contract 102. At operation 128, the device customer 112 can register the device 108 per the smart contract 102. Registration can include registering the device 108 with the device manufacturer 110. Other forms of registration can include the device 108 being placed in-use with or without a service.

At operation 130, the vulnerability assessor 114 can report any vulnerabilities to the blockchain 104 in accordance with the smart contract 102. Operation 130 can be performed as an ongoing monitoring and reporting process. At operation 132, the device customer 112 can be compensated, in accordance with the smart contract 102, for any vulnerability reported by the vulnerability assessor 114. At operation 134, the device manufacturer 110 can perform one or more expected actions to be performed in response to a trigger event (e.g., discovery of a security vulnerability by the vulnerability assessor 114) defined in the smart contract 102.

Turning now to FIG. 2, a method 200 for security management of a device, such as the device 108, will be described, according to an exemplary embodiment. It should be understood that the operations of the methods disclosed herein are not necessarily presented in any particular order and that performance of some or all of the operations in an alternative order(s) is possible and is contemplated. The operations have been presented in the demonstrated order for ease of description and illustration. Operations may be added, omitted, and/or performed simultaneously, without departing from the scope of the concepts and technologies disclosed herein.

It also should be understood that the methods disclosed herein can be ended at any time and need not be performed in its entirety. Some or all operations of the methods, and/or substantially equivalent operations, can be performed by execution of computer-readable instructions included on a computer storage media, as defined herein. The term “computer-readable instructions,” and variants thereof, as used herein, is used expansively to include routines, applications, application modules, program modules, programs, components, data structures, algorithms, and the like. Computer-readable instructions can be implemented on various system configurations including single-processor or multiprocessor systems, minicomputers, mainframe computers, personal computers, hand-held computing devices, microprocessor-based, programmable consumer electronics, combinations thereof, and the like.

Thus, it should be appreciated that the logical operations described herein are implemented (1) as a sequence of computer implemented acts or program modules running on a computing system and/or (2) as interconnected machine logic circuits or circuit modules within the computing system. The implementation is a matter of choice dependent on the performance and other requirements of the computing system. Accordingly, the logical operations described herein are referred to variously as states, operations, structural devices, acts, or modules. These states, operations, structural devices, acts, and modules may be implemented in software, in firmware, in special purpose digital logic, and any combination thereof. As used herein, the phrase “cause a processor to perform operations” and variants thereof is used to refer to causing one or more processors disclosed herein to perform operations.

For purposes of illustrating and describing some of the concepts of the present disclosure, the methods disclosed herein may be described as being performed, at least in part, by one of the processors via execution of one or more software modules. It should be understood that additional and/or alternative devices and/or network nodes can provide the functionality described herein via execution of one or more modules, applications, and/or other software. Thus, the illustrated embodiments are illustrative, and should not be viewed as being limiting in any way.

The method 200 begins and proceeds to operation 202, where at least one of the computing systems 106 creates, for execution on the blockchain 104, the smart contract 102 for the device 108. In particular, the smart contract 102 can identify the parties to an agreement and the obligations of each. From operation 202, the method 200 proceeds to operation 204, where at least one of the computing systems 106 encodes, in the smart contract 102, one or more expected actions to be performed by the device manufacturer 110 in response to one or more trigger events, such as the discovery of a security vulnerability by the vulnerability assessor 114.

From operation 204, the method 200 proceeds to operation 206, where the smart contract 102 on the blockchain 104 detects a trigger event. From operation 206, the method 200 proceeds to operation 208, where, in response to the trigger event, at least one of the computing systems 106 can execute the smart contract 102 to cause one or more expected actions to be performed by the device manufacturer 110. From operation 208, the method 200 proceeds to operation 210, where the method 200 ends. It should be understood that after a trigger event has been detected, the smart contract 102 can continue monitoring for one or more additional trigger events based upon the specification of the smart contract 102 and can perform one or more expected action in response.

The device manufacturer 110 and the device customer 112 can have encoded in the smart contract 102 that if the vulnerability is not fixed within 24 hours (maybe after 24 hours it is published again by the vulnerability assessor 114), then an automatic action of payment, free service, discount, and/or some other form of compensation will be provided to the customer/user/service provider. In another example, if the customer device 112 reaches the agreed upon end-of-life (e.g., 3 years), then the device manufacturer 110 will be relieved in the smart contract 102 of any obligations regarding fixing vulnerabilities.

Turning now to FIG. 3 is a block diagram illustrating a computer system 300 configured to provide the functionality in accordance with various embodiments of the concepts and technologies disclosed herein. The systems, devices, and other components disclosed herein can utilize, at least in part, an architecture that is the same as or at least similar to the architecture of the computer system 300. For example, the computing system(s) 106, the device 108, one or more systems associated with the device manufacturer 110, and/or one or more systems associated with the vulnerability assessor 114 can utilize, at least in part, an architecture that is the same as or at least similar to the architecture of the computer system 300.
