Description

  Embodiments described herein relate generally to a communication system, a communication method, and a portable electronic device that perform information communication in a contactless manner between the portable electronic device and a processing device.

  In general, an IC card used as a portable electronic device includes a card-like main body formed of plastic or the like and an IC module embedded in the main body. The IC module has an IC chip. The IC chip has a nonvolatile memory such as an EEPROM (Electrically Erasable Programmable Read-Only Memory) or a flash ROM that can hold data even in the absence of a power source, and a CPU that executes various operations.

  The IC card is excellent in portability and can perform communication with an external device and complicated calculation processing. Further, since it is difficult to forge, the IC card is assumed to store highly confidential information and be used for a security system, electronic commerce, and the like.

  In recent years, IC cards capable of transmitting and receiving data by non-contact communication have become popular. The non-contact IC card as described above includes an IC chip and an antenna. This non-contact IC card operates by receiving a magnetic field generated from a reader / writer of a terminal device that processes the IC card and causing an antenna in the card to generate electricity by electromagnetic induction.

  By the way, when there are a plurality of IC cards within the communicable range, a state where the IC card processing device cannot correctly identify the plurality of IC cards in the initial response may occur. In order to prevent this collision and correctly identify a plurality of IC cards, a collision avoidance process is defined (Non-Patent Document 1).

ISO / IEC (International Organization For Standardization / International Electro technical Commission) 14443

  Non-Patent Document 1 defines bit-oriented anti-collision (Type A) and slot marker method (Type B) as collision avoidance methods. In these methods, when a collision occurs in the first initial response request, the IC card processing device includes the data for designating the communication partner or the data for designating the communication time zone so that the collision does not occur. Make a response request.

  However, the contactless IC card having the target application does not always respond with this second initial response request. In this case, the IC card processing device recognizes a non-contact IC card having a target application and increases the procedure until the processing corresponding to the purpose is started, resulting in a longer communication time.

  Accordingly, there is a need for a communication system, a communication method, and a portable electronic device that can simplify the communication procedure and shorten the communication time as compared with the conventional collision avoidance method.

  According to an embodiment of the present invention for solving the above-described problem, a portable electronic device having at least one application that performs contactless communication with the portable electronic device, the processing being performed A receiving unit that receives an identifier assigned to each application from the device or identifier information representing a part of this identifier in an initial response request, and an application having an identifier including the transmitted identifier or identifier information. And a reply unit that returns an initial response to the processing device, and a selection unit that selects the application and makes a transition to an executable state, and the identifier is an organization that provides the application. There is provided a portable electronic device characterized in that it includes information for identifying an application and information for identifying an application.

Hereinafter, an IC card will be described as an example of the portable electronic device, but the present invention is not limited to the IC card.

FIG. 1 is a block diagram for explaining a configuration example of an IC card processing apparatus 1 that communicates with an IC card 2 according to the present embodiment.
As shown in FIG. 1, the IC card processing apparatus 1 includes a terminal device 11, a display 12, a keyboard 13, a card reader / writer 14, and the like.

The terminal device 11 includes a CPU, various memories, various interfaces, and the like. The terminal device 11 controls the operation of the entire IC card processing device 1.

The card reader / writer 14 is an interface device for communicating with the IC card 2. The card reader / writer 14 performs power supply, clock supply, reset control, and data transmission / reception with respect to the IC card 2.

The terminal device 11 inputs various commands to the IC card 2 by the card reader / writer 14. For example, when receiving a data write command from the card reader / writer 14, the IC card 2 performs a process of writing the received data into the internal nonvolatile memory.
The terminal device 11 reads data from the IC card 2 by transmitting a read command to the IC card 2. The terminal device 11 performs various processes based on the data received from the IC card 2.

FIG. 2 is a block diagram for explaining a configuration example of the IC card 2 shown in FIG.
As shown in FIG. 2, the IC card 2 includes a card-like main body 21 and an IC module 22 built in the main body 21. The IC module 22 includes one or more IC chips 23 and a communication unit 24. The IC chip 23 and the communication unit 24 are formed in the IC module 22 while being connected to each other.

  The IC chip 23 includes a data bus 20, a communication unit 24, a CPU 25, a ROM 26, a RAM 27, a nonvolatile memory 28, a coprocessor 29, a random number generation circuit 30, and the like. The communication unit 24, the CPU 25, the ROM 26, the RAM 27, the nonvolatile memory 28, the coprocessor 29, and the random number generation circuit 30 are connected to each other via the data bus 20.

  The IC card 2 becomes operable when supplied with power from a higher-level device such as the IC card processing device 1. For example, when the IC card 2 is configured as a non-contact type IC card, the IC card 2 receives a radio wave from the IC card processing device 1 via an antenna as a communication unit, and a power source (not shown) from the radio wave. An operation power supply and an operation clock are generated and activated by the unit.

  The communication unit 24 is an interface for communicating with the card reader / writer 14 of the IC card processing apparatus 1. The communication unit 24 includes, for example, a transmission / reception antenna that performs wireless communication with the card reader / writer 14 of the IC card processing device 1, and a modulation / demodulation unit that modulates transmission data and demodulates reception data.

  The CPU 25 functions as a control unit that controls the entire IC card 2. The CPU 25 performs various processes based on the control program and control data stored in the ROM 26 or the nonvolatile memory 28.

  The ROM 26 is a non-volatile memory that stores a control program and control data in advance. The ROM 26 is incorporated in the IC card 2 in a state where a control program, control data, and the like are stored at the manufacturing stage. That is, the control program and control data stored in the ROM 26 are incorporated in advance according to the specifications of the IC card 2.

  The RAM 27 is a volatile memory that functions as a working memory. The RAM 27 temporarily stores data being processed by the CPU 25. For example, the RAM 27 temporarily stores data received from the IC card processing device 1 via the communication unit 24. The RAM 27 temporarily stores a program executed by the CPU 25.

  The non-volatile memory 28 is configured by a non-volatile memory capable of writing and rewriting data, such as an EEPROM or a flash ROM. The non-volatile memory 28 stores a control program, an application, and various data according to the usage application of the IC card 2.

  For example, in the nonvolatile memory 28, a program file and a data file are created. A control program and various data are written in each created file. The CPU 25 can implement various processes by executing a program stored in the nonvolatile memory 28 or the ROM.

The coprocessor 29 decrypts the encrypted data using the encryption key and encrypts the plaintext data. That is, the coprocessor 29 functions as an encryption processing unit. For example, the CPU 25 inputs data to be encrypted to the coprocessor 29 via the bus 20. In this case, the CPU 25 functions as a data input unit. The coprocessor 29 performs encryption processing on the input data and outputs it to the CPU 25 via the bus 20.
The random number generation circuit 30 generates a random number.

Prior to describing the communication method according to the embodiment of the present invention, a conventional collision avoidance processing method will be described.
FIG. 3 is a diagram showing a communication flow of a collision avoidance process (bit-oriented anti-collision) executed by the non-contact IC card 2 conforming to ISO / IEC14443 Type A and the IC card processing apparatus 1. Here, the card A has an individual number (UID: Unique Identifier) “b” 000... (4 bytes) ”, and the card B has a UID“ b ”001.

  In step S01, the card A and the card B that have received the initial response request from the IC card processing apparatus 1 execute the initial response in step S02. In step S03, the IC card processing apparatus 1 recognizes the collision and transmits a UID read request. In step S04, the card A and the card B that have received the UID read request each execute a response including the UID.

  In response to the reply, the IC card processing device 1 recognizes at which bit position the collision has occurred, and determines the UID up to the location where the collision occurred and the bits “0” and “1” of the location of the collision. In step S05, the IC card processing apparatus 1 sets the bit of the collision location to “0”, transmits the UID (b ”000”) up to here to the card A and the card B, and returns a card that matches this. Request. In this case, the card B responds, and the card B responds including the remaining UID in step S06. Next, in step S07, the IC card processing apparatus 1 requests a reply of the card having the UID (b "001"). In step S08, the corresponding card A responds including the remaining UID.

  In accordance with such a procedure, the IC card processing apparatus 1 recognizes a plurality of cards.

  FIG. 4 is a diagram showing a communication flow of a collision avoidance process (slot marker) executed by the non-contact IC card 2 compliant with ISO / IEC14443 Type B and the IC card processing apparatus 1.

  In step S11, the IC card processing apparatus 1 transmits an initial response request. In step S12, the card A and the card B that have received the initial response request (designating the number of slots 1) make an initial response. At this time, when the IC card processing device 1 recognizes the collision, it transmits an initial response request (designating the number of slots 2) again in step S13.

  The card A and card B that have received the initial response request again generate a random number by the random number generation circuit 30 and confirm 1 bit of a part of the random number. A value obtained by adding “1” to the value indicated by 1 bit is used as the slot number of the card itself. In this way, the non-contact IC card 2 selects an arbitrary number from the values 2 to 1 specified in the initial response request. In FIG. 4, since the card A selects the slot 2 and the card B selects the slot 1, the card B makes an initial response in step S14. Subsequently, in step S15, the IC card processing apparatus 1 transmits a response request to the card that has selected slot 2, and in step S16, card A that has selected slot 2 responds.

  In step S <b> 17, the IC card processing apparatus 1 transmits a selection instruction to the card B. The card B shifts the selected application to an executable state and transmits selection completion to the IC card processing apparatus 1. In step S <b> 18, the IC card processing apparatus 1 transmits a selection instruction to the card A. The card A shifts the selected application to an executable state, and transmits selection completion to the IC card processing apparatus 1.

  As shown in FIGS. 3 to 4, in the conventional collision avoidance method, when the card A is a card having a target application, the IC card processing device 1 recognizes the card A having the target application, There is a problem that the procedure for starting the process according to the purpose increases and the communication time becomes long.

Subsequently, as a communication method according to the embodiment of the present invention, an initial response procedure in the case where a plurality of cards each include a plurality of applications will be described.
As such an example, when the card A of the financial institution has an application AP1 that processes debiting from the owner's account and an application AP2 that provides the owner's personal information (address, name, face photo, etc.) Is mentioned. Similarly, the card B includes an application BP1 and an application BP2.

Each application is assigned a unique application identifier. For example, application identifiers A1 and A2 are assigned to application AP1 and application AP2, respectively, and application identifiers B1 and B2 are assigned to application BP1 and application BP2, respectively.
Here, it is assumed that the application identifiers A1, A2, B1, and B2 are different from each other.

FIG. 5 is a diagram showing the configuration of the application identifier according to the embodiment of the present invention.
The application identifier includes a classification number and an application number. The classification number is a number that identifies the organization that provided the application. For example, in the above-described example, it is a number that identifies a specific financial institution. The application number is a unique number determined by the above institution for specifying the application.

  If each institution assigns a unique application number to the application, the application identifier of this system is also unique. Note that the application identifier is not limited to numerals, and may be configured by arbitrarily combining alphabets and special symbols.

  FIG. 6 is a diagram illustrating a flowchart of an initial response process executed by the non-contact IC card 2 and the IC card processing apparatus 1 according to the first embodiment. This flow shows an example of an initial response process in which one application identifier is designated.

  In step S21, the IC card processing apparatus 1 transmits an initial response request including one application identifier. The cards A and B that have received the initial response request to which the application identifier A1 is given from the IC card processing apparatus 1 confirm whether there is an application having the designated application identifier A1. In FIG. 6, the card A stores an application having the application identifier A1. Accordingly, the card A makes an initial response.

  In step S22, the card A returns an initial response to the IC card processing apparatus 1. The contents returned at this time include information indicating the card A and the application identifier A1. Further, the card A that initially responded can select and execute the application with the identifier A1 presented at that time.

  The IC card processing apparatus 1 that has received the initial response indicates that there is a card having an application having the application identifier A1, and that the card can select and execute the application having the identifier A1 at this time. Recognize

  According to the first embodiment, anti-collision can be realized by presenting the application identifier to the non-contact IC card 2 in the initial response request. Further, the contactless IC card 2 that has made an initial response can select and execute an application having the presented application identifier at that time. Therefore, the application selection instruction procedure defined in the conventional communication method is not necessary.

(Second Embodiment)
In the second embodiment, the initial response procedure is different from that of the first embodiment. The same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  FIG. 7 is a diagram illustrating a flowchart of an initial response process executed by the non-contact IC card 2 and the IC card processing apparatus 1 according to the second embodiment. This flow shows an example of initial response processing in which a plurality of application identifiers are specified.

  In step S31, the IC card processing apparatus 1 transmits an initial response request including a plurality of application identifiers. Then, an initial response of the non-contact IC card 2 including an application having any one of the plurality of application identifiers is requested. Here, it is assumed that the plurality of application identifiers are A1 and A3.

  The cards A and B that have received the initial response request to which the application identifiers A1 and A3 are assigned from the IC card processing apparatus 1 confirm whether there is an application having the designated application identifier A1 or A3. In FIG. 7, the card A stores an application having the application identifier A1. Accordingly, the card A makes an initial response.

  In step S32, the card A returns an initial response to the IC card processing apparatus 1. The contents returned at this time include information indicating the card A and the application identifier A1. Further, the card A that initially responded can select and execute the application with the identifier A1 presented at that time.

  The IC card processing apparatus 1 that has received the initial response indicates that there is a card having an application having the application identifier A1, and that the card can select and execute the application having the identifier A1 at this time. Recognize

  If there is a card having both of the application identifiers A1 and A3, the card includes information specifying the card and information indicating the application identifier A1 indicated first among the presented identifiers. Return to processing device 1. Then, the card that initially responded can select and execute the application of the identifier A1 indicated first among the identifiers presented at that time.

  The IC card processing apparatus 1 that has received the initial response indicates that there is a card having an application having the application identifier A1 or A3, and that the card can select and execute an application having the identifier A1 at this time. Recognize that

(Third embodiment)
In the third embodiment, the initial response procedure is different from that of the first embodiment. The same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  FIG. 8 is a diagram illustrating a flowchart of an initial response process executed by the non-contact IC card 2 and the IC card processing device 1 according to the third embodiment. This flow shows an example of initial response processing in which a plurality of application identifiers are specified.

  In step S41, the IC card processing apparatus 1 transmits an initial response request including a plurality of application identifiers. Then, an initial response of the non-contact IC card 2 having an application having all of the plurality of application identifiers is requested. Here, it is assumed that the plurality of application identifiers are A1 and A2.

  The cards A and B that have received the initial response request to which the application identifiers A1 and A2 are assigned from the IC card processing apparatus 1 check whether there is an application having the designated application identifiers A1 and A2. In FIG. 7, the card A stores an application having an application identifier A1 and an application having an application identifier A2. Accordingly, the card A makes an initial response.

  In step S <b> 42, the card A returns an initial response to the IC card processing device 1. The contents returned at this time include information indicating the card A and the application identifier A1 designated first among the presented identifiers. Further, the card A that has made an initial response selects and executes the application of the identifier A1 indicated first among the identifiers presented at that time.

  The IC card processing apparatus 1 that has received the initial response indicates that there is a card having an application having application identifiers A1 and A2, and that the card can select and execute an application having the identifier A1 at this time. Recognize that

  In the above-described embodiment, the application identifier is included in the information communicated in the initial response, but this information may be a part of the application identifier. For example, even if the application identifier includes an information part indicating the function of the application and an information part related to the user, the information may be information that allows the card to identify the application.

Next, an application example of this embodiment will be described.
In the present embodiment, a unique application identifier is assigned to the application. The application identifier includes a number for identifying the organization that provided the application and a number for identifying the application. In this aspect, each application can be handled independently so as to correspond to one card. Therefore, when the IC card processing apparatus 1 directly designates an application, a phase for specifying a card that is necessary in the conventional initial response is not necessary.

  On the other hand, in order to enable this mode, it is a premise that it is necessary to grasp the application identifier to be processed by the IC card processing apparatus 1 in the state before communication. The following can be considered as examples of this embodiment.

(1) A mode in which a plurality of conventional IC cards are combined into one common IC card
For example, the IC cards of the financial institution X and the financial institution Y are combined into one common IC card. The application included in each card is given an application identifier having the system shown in FIG. 5 and can be uniquely identified. The user designates or inputs a financial institution to be processed with respect to the IC card processing apparatus 1. Then, the IC card processing apparatus 1 can specify a desired application by combining the classification number corresponding to this financial institution with the information specifying the application to be handled.

(2) A mode in which a plurality of different applications are read from a non-contact IC card on the premise of reading one sheet by the dedicated IC card processing device 1
For example, a case where an IC card processing device 1 that processes a passport designates an application for a passport card, and a case that an IC card processing device 1 that processes a driver's license designates an application in the driver's license card are applicable. In this aspect, the contactless IC card to be processed is fixed. Therefore, even if there is no user input, the IC card processing apparatus 1 can generate an application identifier by generating a classification number. Since the application identifier is unique, the IC card processing apparatus 1 can specify a desired application.

[effect]
According to the embodiment described above, various effects can be achieved.

  In the present embodiment, only the non-contact IC card 2 having a specific application is presented by presenting the application identifier owned by the non-contact IC card 2 or a part thereof in the initial response request from the IC card processing device 1. In order to respond, collision avoidance can be realized with a single initial response request.

  Further, since the contactless IC card 2 that has made an initial response selects an application at that time and is in an executable state, an application selection instruction after the initial response can be omitted.

  Therefore, by using this embodiment, the communication procedure can be simplified and the communication time can be shortened as compared with the conventional collision avoidance method.

  Note that the functions described in the above-described embodiments are not limited to being configured using hardware, and can be realized by causing a computer to read a program describing each function using software. Each function may be configured by appropriately selecting either software or hardware.

Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage.
Various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, you may combine suitably the component covering different embodiment.
