20160112454
This application claims priority from and the benefit under 35 U.S.C. §119(a) of Korean Patent Application No. 10-2014-0141545, filed on Oct. 20, 2014, which is hereby incorporated by reference for all purposes as if fully set forth herein.
The present disclosure relates generally to an electronic device having a security communication function and a method of allowing an electronic device to communicate with an external device through the function.
Communication networks have layered architectures, where each layer is responsible for data transfer. Communication networks may follow a general pattern such as an Open Systems Interconnection (or “OSI”) model. In the OSI model, each layer has the same data format. According to the data format, each piece of binary data (such as, for example, a packet or a frame) may include a header and a payload.
The header may include layer-specific information and metadata on a corresponding layer to process data. The metadata is utilized to accurately process the payload by the corresponding layer. For example, the payload of a highest layer includes application data. Any layer transfers data including a payload (that is, including a header and a payload of a higher layer) and a header thereof to a lower layer. For example, the payload of the highest layer may include application data.
A user device may process security of data (such as, for example, process ciphering or integrity checking) in any layer according to the OSI model and transmit the processed data to a counterpart device. For example, an application layer may process security of application data (such as voice data).
Any layer (such as a transport layer or a network layer) lower than the application layer may perform security processing of a payload. Then, not only the application data but also a header (e.g., metadata) corresponding to a higher layer is also security-processed. However, the counterpart device may not process (e.g., decipher the ciphered metadata) the security-processed data in the same layer and, accordingly, may not accurately operate on the application data. For example, as a result, an inaccurate or distorted user voice may be output through a speaker of the counterpart device. Further, a connection between two devices may be interrupted or disconnected entirely.
In view of the foregoing, an aspect of the present disclosure is to provide a method of allowing communication with the counterpart device by dynamically (i.e., selectively) setting a layer to perform security processing, and an electronic device for implementing the same.
In accordance with an aspect of the present disclosure, a method of communicating data by an electronic device, including negotiating with a counterpart device for a security layer to perform security processing of data, determining at least one layer as the security layer based on the negotiation outcome, and communicating with the counterpart device using the security layer.
In accordance with another aspect of the present disclosure, an electronic device is disclosed, including a communication unit for communicating with a counterpart device through a communication network, and at least one processor configured to negotiate via the communication unit with the counterpart device for a security layer to perform security processing of data, determine at least one layer as the security layer based on the negotiation outcome, and communicate with the counterpart device using the security layer.
In accordance with another aspect of the present disclosure, a non-transitory computer-readable recording medium having commands stored therein, the commands are configured to allow one or more processors to perform one or more operations when executed by the one or more processors, the one or more operations including negotiating with a counterpart device for a security layer to perform security processing of data, determining at least one of the layers as the security layer based on the negotiation outcome, and communicating with the counterpart device by using the security layer.
The present disclosure provides a method of allowing communication with a counterpart device by dynamically and/or selectively setting a layer to perform security processing, and an electronic device for implementing the same.

In various embodiments, an external device and a counterpart device correspond to electronic devices having a security communication function. The terms “external” and “counterpart” refer to other electronic devices from a viewpoint of one electronic device, and it should be understood that the terms “external” and “counterpart” do not limit functions or operations of the corresponding devices.
Hereinafter, an electronic device according to various embodiments and a method implemented by the electronic device will be described with reference to the accompanying drawings.
The display panel may include a touch panel 111 implementing an input unit for facilitating interaction between the user and the electronic device 100. Then, the display unit 110 may be interchangeable with a touch screen.
The touch panel 111 may be implemented in an add-on type in which the touch panel 111 is located on the screen of the display unit 110, or an on-cell type or an in-cell type in which the touch panel 111 is inserted into the display unit 110. The touch panel 111 may detect a user input in at least one of, for example, a capacitive type, resistive type, an infrared type, or an ultrasonic wave type, generate an event corresponding to the user input, and transfer the generated event to the controller 170.
The touch panel 111 may detect a gesture of a conductive object (for example, a finger or a stylus) which directly contacts the screen or is proximate or hovering within a predetermined range in which the touch panel 111 can detect the object. The touch panel 111 may generate an event corresponding to the gesture and transfer the generated event to the controller 170.
The input unit 120 may include, for example, a touch key which is different from the touch panel 111 installed in the display unit 110. The touch key may recognize a touch or proximity of a human body and an object. The input unit 120 may generate an event in response to a user input and transfer the generated event to the controller 170. The input unit 120 may further include a key (for example, a dome key) in one type different from the touch type. For example, when the user presses the dome key, the dome key is transformed to contact a printed circuit board and, accordingly, a key event is generated on the printed circuit board and transmitted to the controller 170.
The storage unit 130 may store data such as SMS, MMS, SNS message, and email data, as generated by the electronic device 100 or received from an external device through the communication unit 140 under a control of the controller 170. The storage unit 130 may store a booting program, at least one operating system, and any installed applications. Further, the storage unit 130 stores various pieces of user settings and/or configuration information (such as screen brightness or the like) for controlling and optimizing a user environment of the electronic device 100. Accordingly, the controller 170 may operate the electronic device 100 with reference to the setting/configuration information.
The storage unit 130 may include a main memory and a secondary memory. The main memory may be implemented by, for example, a Random Access Memory (RAM). The secondary memory may be implemented by a disc, a RAM, a Read Only Memory (ROM), or a flash memory. The main memory may store various programs, for example, a booting program, an operating system (such as, for example, a kernel), middleware, an Application Programming Interface (API), and an application, loaded from the secondary memory. When electrical power is supplied to the controller 170, the booting program may be first loaded to the main memory. The booting program may load the operating system to the main memory. The operating system may load the application to the main memory. The controller 170 may access the main memory to decipher a command (routine) of a program, and execute a function according to a result of the deciphering.
The storage unit 130 may further include an external memory. For example, the storage unit 130 may include Compact Flash (CF), Secure Digital (SD), Micro-Secure Digital (Micro-SD), Mini-Secure Digital (mini-SD), extreme Digital (xD), or a memory stick, as the external memory.
The storage unit 130 may store a security layer negotiation module 131. The security layer negotiation module 131 may be configured to allow the electronic device 100 to perform a function of negotiating with a counterpart device about a device to perform security processing of data and determining the device. The negotiation may be defined as a process for matching layers (hereinafter, referred to as a “security layer”), which perform the security processing, between devices.
The storage unit 130 may store at least one security processing module 132-134. The security processing module 132-134 serves to perform security processing of at least one layer. For example, security processing modules 132, 133, and 134 shown in
Any component of the electronic device 100, such as the processor 171 may perform security processing of data by using the security processing module corresponding to the security layer. For example, when the layer determined as the security layer corresponds to the presentation layer, the processor may perform security processing (such as ciphering) of data ciphered by a codec (such as Adaptive MultiRate or “AMR”) using the security processing module 132.
When the layer determined as the security layer corresponds to the transport layer, the processor may perform security processing (such ciphering, authentication, and integrity checking) of data using the security processing module 133, which may be for example, a Secure Real-Time Transport Protocol (“SRTP”) or Transport Layer Security (“TLS”). When the layer determined as the security layer corresponds to the network layer, the processor may perform security processing, such as, ciphering and authentication checking of data, using the security processing module 134 (e.g., Internet Protocol security or “IPsec”). Meanwhile, a security processing module, which manages another layer (e.g., an application layer) as well as the above described layers, may be further stored in the storage unit 130.
The communication unit 140 may perform data communication (e.g., a voice call, a video call, an SMS, or an Internet service) with an external device 10 through a communication network (e.g., LTE, wireless LAN, or the like) under a control of the controller 170. The communication unit 140 may directly perform the data communication with an external device 20 through a designated frequency channel without a relay of the network (e.g., without a relay of an Access Point or “AP”).
The speaker 150 converts the audio signal received from the controller 170 into a sound wave and outputs the sound wave. The microphone 160 may convert sound waves transferred from the person or other sound sources into audio signals and output the audio signals to the controller 170.
The controller 170 controls general operations of the electronic device 100 and a signal flow between internal components of the electronic device 100, process data, and controls power supply to the components from the battery.
The controller 170 may include a processor 171. The processor 171 may include an Application Processor (AP), a Communication Processor (CP), a Graphic Processing Unit (CPU), and an audio processor. The CP may be a component of the communication unit 140.
The processor 171 (e.g., the AP) may load a command or data received from a non-volatile memory (e.g., a memory used as the secondary memory) or another component connected to the processor 171 or at least one of the other components to a volatile memory (e.g., a memory used as the main memory) and process the loaded command and data. Further, the processor 171 may store data received from or generated by at least one of other components in the non-volatile memory.
The processor 171 (e.g., the AP) may dynamically set a security layer by using the security layer negotiation module 131 and implement a method of performing security processing of the data in the security layer. Hereinafter, a method according to various embodiments of the present disclosure will be described in detail.
The electronic device 100 may further include components which have not been mentioned above, such as an ear jack, a proximity sensor, an illumination sensor, a Subscriber Identification Module (SIM) card, a camera, and the like. Further, the electronic device 100 may further include an interface unit for a wired connection with an external device. The interface unit may be connected to the external device through a wire (e.g., a USB cable). Then, the controller 170 may perform data communication with the external device through the interface unit.
The cellular module 210 may perform data communication through a mobile communication network (e.g., LTE, LTE-A, CDMA, WCDMA, UMTS, WiBro, GSM, or the like). The cellular module 210 may authenticate the electronic device 100 by using, for example, a subscriber identification module (e.g., a SIM card).
The cellular module 210 may include a processor 211 (e.g., a CP). The processor 211 may perform at least some of the functions (e.g., at least some of the multimedia control functions) provided by the processor 171. Further, the processor 211 may perform security processing of data by using the security processing module (e.g., the security processing module 133) corresponding to the negotiated layer. Although the processor 211 is illustrated as an internal component of the cellular module 210, the processor 211 may be configured in the electronic device 100 separately from the cellular module 210 according to an embodiment.
The cellular module 210 may be implemented by, for example, an SoC. Although the components such as the cellular module 210 and the storage unit 130 are illustrated as components separated from the processor 171, the processor 171 may include at least some (e.g., the CP) of the above described components according to an embodiment.
The cellular module 210 may load commands or data received from a connected non-volatile memory or at least one other component to a volatile memory and process the loaded commands or data. Further, the cellular module 210 may store data received from or generated by at least one of other component in a non-volatile memory.
Each of the Wi-Fi module 220, the BT module 230, the NFC module 240, and the GPS module 250 may include, for example, a processor for processing data transmitted/received through the corresponding module. Alternatively, the processor 211 or the processor 171 may serve to process the data transmitted/received through the modules.
Although the cellular module 210, the Wi-Fi module 220, the BT module 230, the NFC module 240, and the GPS module 250 are illustrated as separate blocks in
The RF module 260 may transmit/receive data, for example, RF signals. Although not illustrated, the RF module 260 may include, for example, a transceiver, a Power Amp Module (“PAM”), a frequency filter, a low noise amplifier (“LNA”), or the like.
The RF module 260 may further include an element for transmitting/receiving electronic waves over free air space in wireless communication, such as, a conductor, a conducting wire, or the like. Although the cellular module 210, the Wi-Fi module 220, the BT module 230, the NFC module 240, and the GPS module 250 may share one RF module 260 in

According to an embodiment, when information indicating one or more layers of the electronic device 100 supporting security processing is included in the request message, the response message may include information indicating that the counterpart device selects one of the one or more layers as the security layer.
According to another embodiment, the request message may include information indicating an inquiry (e.g., a request) about a layer of the counterpart device supporting the security processing. Accordingly, the response message may include information indicating at least one layer of the counterpart device supporting the security processing.
According to another embodiment, the request message may include information indicating the content which makes a request for setting a particular layer as the security layer. Accordingly, the response message may include information indicating an acceptance of the request.
In operation 330, the processor of the electronic device 100 may determine at least one of the layers of the electronic device 100 as the security layer based on the response message. Accordingly, the determined layer may be the same as the security layer of the counterpart device through the negotiation process.
According to an embodiment, the processor of the electronic device 100 may identify the response message to recognize which layer of the counterpart device is selected as the security layer and determine the selected layer as the security layer.
According to another embodiment, the processor of the electronic device 100 may identify the response message to recognize which layer of the counterpart device supports the security processing and determine the recognized layer as the security layer. Additionally, the processor of the electronic device 100 may control the communication unit 140 to transmit a confirmation message for informing that the security layer is determined to the counterpart device. In response to the confirmation message, the counterpart device may determine the same as the layer determined by the electronic device 100 to be the security layer.
According to another embodiment, the processor of the electronic device 100 may identify the response message to recognize that the counterpart device accepts the “request for setting the particular layer as the security layer from the electronic device 100” and determine the particular layer as the security layer.
In operation 340, the processor of the electronic device 100 may engage in secure communication with the counterpart device by using the designated security layer. For example, the processor may perform security processing of data by using the security processing module corresponding to the security layer and control the communication unit 140 to transmit the security-processed data to the counterpart device. The processor may decipher (e.g., decode encoded data) the security-processed data, which is received from the counterpart device, by using the security processing module corresponding to the security layer.
Referring to
As the layers may be hierarchically structured, data security in a lower layer may be stronger relative to a higher layer. This is because metadata (e.g., a network port or phone number) as well as application data is security-processed in the lower layer. In such circumstances, among the layers supporting the security processing, a lowest layer may be first selected as the candidate. That is, the first layer may refer to the lowest layer (e.g., network layer) among the layers supporting the security processing.
In operation 420, the processor of the electronic device 100 may inquire the counterpart device about whether the probing layer n supports the security processing. For example, an application layer (e.g., an application for data communication) of the electronic device 100 may generate a security layer negotiation request message including information (e.g., number “n”) on the layer “n” set as the candidate. The communication unit 140 (e.g., the cellular module 210 or the Wi-Fi module 220) may transmit the security layer negotiation request message to the counterpart device in response to a command of the processor.
In operation 430, the processor of the electronic device 100 may receive a result of the inquiry (e.g., a security layer negotiation response message) from the counterpart device through the communication unit 140 and identify the received result of the inquiry. When the inquiry result corresponds to probing success (e.g., information indicating that the security processing can be performed in the layer “n” is included in the response message), the processor of the electronic device 100 may set the probing layer n as the security layer in operation 440.
When the inquiry result corresponds to probing fail (e.g., information indicating that the security processing cannot be performed in the layer “n” is included in the response message), the processor of the electronic device 100 may identify whether n is a maximum value “N” in operation 450. For example, according to the OSI seven-layer structure, the maximum value N may be “7”. That is, in operation 450, the processor of the electronic device 100 may determine whether the negotiation with the counterpart device for all candidates has been made. When n is the maximum value N (i.e., synchronization of the security layer or, matching of the security layer between devices) is not possible even though the negotiation with the counterpart for all candidates has been made, the processor of the electronic device 100 may determine that security communication with the counterpart device is not possible.
When n is not the maximum value N, the processor of the electronic device 100 may reset the next ordered layer “n+1” as the layer “n” in operation 460. That is, the processor may reset the layer, which is one level higher than the previously set layer, as the candidate of the security layer. After resetting the candidate, the processor may repeatedly perform operations 420 and 430.
According to the embodiment described with reference to
According to some embodiments, operation 410 may be an operation for setting a highest layer as the candidate. Then, “N” refers to a minimum value (that is, number indicating a lowest layer) in operation 450, and operation 460 may be an operation for resetting a layer, which is one level lower than the previously set layer, as the candidate of the security layer.
Referring to
In operation 520, the processor of the electronic device 100 may set a layer “n” to be compared as “1”. That is, the processor may set or select a first layer as a target to be compared with a layer notified to enable the security processing to the electronic device 100 by the counterpart device. The first layer may refer to a lowest layer (e.g., a network layer) among the layers supporting the security processing.
In operation 530, the processor of the electronic device 100 may determine whether layer n to be compared is the layer in which the counterpart device can perform security processing. For example, the processor may identify header information on the layer from the request message and compare the identified header information (i.e., header information received from the counterpart device) with header information on the set layer n to be compared.
When the layer n to be compared is the layer in which the counterpart device can perform the security processing (e.g., when two pieces of header information match based on a result of the comparison), the processor of the electronic device 100 may set the layer n to be compared as the security layer in operation 540. Further, the processor may transmit a security layer negotiation response message including information on the security layer to the counterpart device through the communication unit 140.
When the layer n to be compared is not the layer in which the counterpart device can perform the security processing (e.g., when two pieces of header information do not match based on a result of the comparison), the processor of the electronic device 100 may identify whether n is the maximum value “N” in operation 550. For example, according to the OSI seven-layer structure, the maximum value N may be “7”.
That is, in operation 550, the processor of the electronic device 100 may determine whether all layers, in which the electronic device 100 can perform security processing, have been compared with the “layer notified to enable the security processing to the electronic device 100 by the counterpart device”. When n is the maximum value N (i.e., all layers are determined to not match the layer notified by the counterpart), the processor of the electronic device 100 may determine that security communication with the counterpart device is not possible.
When n is not the maximum value N, the processor of the electronic device 100 may reset the next ordered layer “n+1” as the layer “n” in operation 560. That is, the processor may reset the layer, which is one level higher than the previously set layer, as the layer to be compared. After resetting the target to be compared, the processor may repeatedly perform operations 420 and 430.
According to the embodiment described with reference to
According to some embodiments, operation 520 may be an operation for setting a highest layer as the target to be compared. Then, “N” refers to a minimum value (i.e., number indicating a lowest layer) in operation 550, and operation 560 may be an operation for resetting a layer, which is one level lower than the previously set layer, as the target to be compared.
