Embodiments for Carrying Out the Invention

[0015] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The embodiments described below are embodiments when the present invention is applied to an IC card equipped with a plurality of interfaces for communicating with an external terminal and on which a plurality of applications are installed.

[0016] [1. Configuration and Functions of IC Card C] First, with reference to FIG. 1, the configuration and functions of the IC card C according to the present embodiment will be described. FIG. 1 is a diagram showing an example of the schematic configuration of the IC card C. Examples of the IC card C include a credit card, an electronic money card, a card for passing through an entrance / exit gate, and the like. As shown in FIG. 1, the IC card C includes an antenna 1 and an IC chip 2 having a plurality of interfaces. The IC card C and the IC chip 2 are examples of the electronic information storage medium of the present invention. A plurality of different applications (that is, a plurality of applications) corresponding to each of a plurality of different services (for example, payment services) are installed (loaded) on the IC chip 2. In the following description, among the plurality of interfaces, the non-contact communication interface is referred to as "interface I / F1", and the contact communication interface is referred to as "interface I / F2". The interface I / F1 includes non-contact communication terminals (La, Lb) connected to the antenna 1, and performs non-contact communication (for example, non-contact communication conforming to the international standard ISO / IEC 14443) with a non-contact reader / writer of a payment terminal T1 (an example of an external terminal) via the antenna 1 within the non-contact field.

[0017] FIG. 2 is a diagram showing an example of the hardware configuration of the IC chip 2. As shown in FIG. 2, the IC chip 2 includes a CPU (Central Processing Unit) 21, a RAM (Random Access Memory) 22, a ROM (Read Only Memory) 23, a NVM (Nonvolatile Memory) 24, an I / O circuit 25, and the like. The I / O circuit 25 includes, for example, eight terminals C1 to C8 that comply with the international standard ISO / IEC 7816. Here, the C1 terminal is a power supply terminal (VCC), the C2 terminal is a reset terminal (RST) for inputting a reset signal, the C3 terminal is a clock terminal (CLK) for inputting a clock signal, and the C5 terminal is a ground terminal (GND). The C6 terminal is a terminal that serves as an interface I / F1 between the non-contact reader / writer of the payment terminal T1 via the antenna 1 (for example, a terminal used for communication according to the SWP (Single Wire Protocol)). The C7 terminal is a terminal that serves as an interface I / F2 between the contact reader / writer of the payment terminal T2 (an example of an external terminal), for example. Note that the C4 terminal and the C8 terminal can be used as an interface with other external terminals (for example, an interface for USB (Universal Serial Bus) transfer or SPI (Serial Peripheral Interface)).

[0018] The CPU 21 is a processor (computer) that executes programs (including the program of the present invention) stored in the ROM 23 or the NVM 24 (an example of storage means). For example, a flash memory can be applied to the NVM 24. Note that the NVM 24 may be a non-volatile memory such as an "Electrically Erasable Programmable Read-Only Memory". Programs (including the program of the present invention) such as an OS (Operating System) and a plurality of applications operating on the OS, as well as a plurality of management tables TB1 and TB2 are stored in the ROM 23 or the NVM 24. The OS has a basic function that is responsible for the basic operation of the IC chip 2, an interface management function that manages a plurality of interfaces using the management table TB1, and a logical channel management function that manages a plurality of logical channels using the management table TB2.

[0019] Here, the basic function that is responsible for the basic operation of the IC chip 2 includes a function of recognizing an interface in operation among a plurality of interfaces. The interface in operation refers to, for example, an interface activated by the occurrence of a reset event. For example, the reset event of the interface I / F1 occurs when the C6 terminal in the I / O circuit 25 is set to the High state (pullup). Also, the reset event of the interface I / F1 occurs, for example, when the IC card C enters the operating magnetic field emitted by the non-contact reader / writer of the payment terminal T1 and power is supplied to transition to the IDLE state (in accordance with the international standard ISO / IEC 14443-3 "5.2.1 Polling"). On the other hand, the reset event of the interface I / F2 occurs, for example, when the C1 terminal and the C2 terminal (or the C7 terminal) in the I / O circuit 25 are set to the High state. Note that when the interface is activated, a basic logical channel (the logical channel with the channel number ch0) may be opened. The management table TB1 (an example of first management information) defines the interfaces available for each logical channel. On the other hand, the management table TB2 (an example of second management information) defines the logical channels available for each application.

[0020] Figure 3(A) is a diagram showing an example of the management table TB1. In the management table TB1 shown in Figure 3(A), since interface identifiers IF1 and IF2 are associated with the channel number ch0, it indicates that the logical channel of the channel number ch0 is available for use with interfaces I / F1 and I / F2. In other words, the logical channel of the channel number ch0 supports the operations of interfaces I / F1 and I / F2. Also, in the management table TB1 shown in Figure 3(A), since the interface identifier IF2 is associated with the channel number ch1, it indicates that the logical channel (additional logical channel) of the channel number ch1 is available for use only with the interface I / F2. Also, in the management table TB1 shown in Figure 3(A), since the interface identifier IF1 is associated with the channel number ch2, it indicates that the logical channel (additional logical channel) of the channel number ch2 is available for use only with the interface I / F1.

[0021] On the other hand, Figure 3(B) is a diagram showing an example of the management table TB2. In the management table TB2 shown in Figure 3(B), since the channel numbers ch0 to ch2 are associated with the application identifier AID1, it indicates that the application with the application identifier AID1 is available for use with each of the logical channels of the channel numbers ch0 to ch2. In other words, the application with the application identifier AID1 is supported in the operations of each of the logical channels of the channel numbers ch0 to ch2. Also, in the management table TB2 shown in Figure 3(B), since the channel number ch1 is associated with the application identifier AID2, it indicates that the application with the application identifier AID2 is available for use only with the logical channel of the channel number ch1. Also, in the management table TB2 shown in Figure 3(B), since the channel number ch2 is associated with the application identifier AID3, it indicates that the application with the application identifier AID3 is available for use only with the logical channel of the channel number ch2.

[0022] An application is a collection of a plurality of instantiated objects and is an entity that processes commands from an external terminal. Further, files used by the application are stored in the NVM24. Such files include, for example, MF (Master File), DF (Dedicated File), and EF (Elementary File). Each file is identified by a file identifier. The MF is located at the top in the file configuration, and the DF and EF are located in the lower hierarchy (subordinates) of the MF. Further, for example, a DF (application DF) may be provided for each application under the MF. The EF under each application DF stores data used by each application. Further, the EF is divided into IEF and WEF. The IEF stores a PIN (collation key) such as a session key, for example.

[0023] In the IC chip 2 configured as described above, the CPU 21 functions as the receiving means, the first determination means, the second determination means, and the processing means in the present invention by executing the program of the present invention. Specifically, when the CPU 21 receives a predetermined command from an external terminal (T1 or T2) via one of the plurality of interfaces that is operating, in response to the reception of the command, it determines based on the management table TB1 whether one logical channel to be opened among the plurality of logical channels is available on the one operating interface, and determines based on the management table TB2 whether one application to be selected among the plurality of applications is available on the one logical channel to be opened.

[0024] Here, the application to be selected, which is 1, refers to an application that is default-assigned to any one or more logical channels, or an application indicated by the SELECT command defined in ISO / IEC 7816-4 (that is, specified by the SELECT command). The application that is default-assigned to any one or more logical channels is an application that can be implicitly selected on the corresponding logical channel and is managed separately (independently) from the management table TB2 by the logical channel management function of the OS. The SELECT command is composed of a command APDU (Application Protocol Data Unit) that includes a header part consisting of CLA, INS, P1, and P2, and a body part consisting of Data and the like. In the SELECT command, for example, the file identifier of the file used by the application to be selected is encoded by P1, and the application identifier of the application to be selected is included in the Data of the body part.

[0025] Also, the logical channel to be opened, which is 1, refers to, for example, an unopened logical channel. Examples of commands for opening a logical channel include the above SELECT command and the MANAGE CHANNEL command defined in ISO / IEC 7816-4. The MANAGE CHANNEL command is composed of a command APDU that includes a header part consisting of INS, P1, and P2 (it may also include a body part). In the SELECT command, for example, the channel number of the logical channel to be opened is encoded by CLA. On the other hand, in the MANAGE CHANNEL command, for example, the channel number of the logical channel to be opened is encoded by P2. Note that the logical channel to be opened, which is 1, may be a basic logical channel opened by activating the interface. In this case, the channel number of the basic logical channel to be opened by the SELECT command does not have to be encoded by CLA.

[0026] Then, when the CPU 21 determines that one logical channel to be opened is available on one interface that is in operation, and also determines that one application to be selected is available on the one logical channel to be opened, the CPU 21 executes a process of opening the one logical channel to be opened and selecting the one application to be selected. On the other hand, when the CPU 21 determines that the one logical channel to be opened is not available on the one interface that is in operation, or determines that the one application to be selected is not available on the one logical channel to be opened, the CPU 21 executes error processing.

[0027] [2. Operation of IC Card C] Next, the operation of the IC card C will be described separately for Example 1 and Example 2. In Example 1 and Example 2, for example, an initialization sequence (including an initial response from the IC chip 2, etc.) is executed on any one interface due to the occurrence of a reset event, and it is assumed that the interface is activated (operating).

[0028] (Example 1) First, with reference to FIG. 4, the operation of the IC card C in Example 1 will be described. FIG. 4 is a flowchart showing an example of a logical channel opening process executed by the CPU 21 (for example, an OS) of the IC chip 2 in Example 1. The process shown in FIG. 4 starts when a MANAGE CHANNEL command is received from an external terminal via an operating interface.

[0029] When the process shown in FIG. 4 starts, the CPU 21 identifies the operating interface (for example, by an interface identifier) (step S1). Next, the CPU 21 identifies the logical channel to be opened indicated by the MANAGE CHANNEL command (for example, by a channel number) (step S2). Next, the CPU 21 determines based on the management table TB1 whether the logical channel identified in step S2 is available on the interface identified in step S1 (step S3).

[0030] If it is determined that the logical channel specified in step S2 is not available on the interface specified in step S1 (step S3: NO), error processing is performed (step S4). In such error processing, for example, a response APDU including status words SW1 and SW2 indicating an error is transmitted to an external terminal via the operating interface. On the other hand, if it is determined that the logical channel specified in step S2 is available on the interface specified in step S1 (step S3: YES), the process proceeds to step S5.

[0031] In step S5, the CPU 21 opens the logical channel specified in step S2. Next, the CPU 21 determines whether there is an application that is assigned by default to the logical channel specified in step S2 (step S6). If it is determined that there is no application assigned by default (step S6: NO), a response APDU including status words SW1 and SW2 indicating normal termination is transmitted to an external terminal via the operating interface (step S7). Such a response APDU may include the channel number of the opened logical channel. On the other hand, if it is determined that there is an application assigned by default (step S6: YES), the process proceeds to step S8. Note that if it is determined that there is an application assigned by default, the process may proceed to step S10.

[0032] In step S8, the CPU 21 determines, based on the management table TB2, whether the application assigned by default can be used on the logical channel specified in step S2. If it is determined that the application assigned by default cannot be used on the logical channel specified in step S2 (step S8: NO), error processing is performed in the same manner as in step S4 (step S9). As a result, even when an application is assigned by default to a logical channel, it is possible to determine whether it can be used on that logical channel according to the subsequently issued management table TB2, thus enhancing the convenience of the IC card C.

[0033] On the other hand, if it is determined that the application assigned by default can be used on the logical channel specified in step S2 (step S8: YES), the process proceeds to step S10. In step S10, the CPU 21 selects the application assigned by default. Next, the CPU 21 transmits a response APDU including status words SW1 and SW2 indicating normal termination to the external terminal via the operating interface (step S11). Such a response APDU includes FCI (File Control Information) regarding the file used by the selected application.

[0034] (Embodiment 2) Next, with reference to FIG. 5, the operation of the IC card C in Embodiment 2 will be described. FIG. 5 is a flowchart showing an example of logical channel establishment processing executed by the CPU 21 (for example, an OS) of the IC chip 2 in Embodiment 2. The processing shown in FIG. 5 starts when a SELECT command is received from the external terminal via the operating interface.

[0035] When the process shown in FIG. 5 starts, the CPU 21 identifies the interface in operation (step S21). Next, the CPU 21 identifies the logical channel to be opened indicated by the SELECT command (step S22). If the basic logical channel has already been opened, the basic logical channel is identified. Next, the CPU 21 identifies the application to be selected indicated by the SELECT command (for example, identified by the application identifier) (step S23).

[0036] Next, the CPU 21 determines based on the management table TB1 whether the logical channel identified in step S22 is available on the interface identified in step S21 (step S24). If it is determined that the logical channel identified in step S22 is not available on the interface identified in step S21 (step S24: NO), error processing is performed in the same manner as in step S4 above (step S25). On the other hand, if it is determined that the logical channel identified in step S22 is available on the interface identified in step S21 (step S24: YES), the process proceeds to step S26.

[0037] In step S26, the CPU 21 determines based on the management table TB2 whether the application identified in step S23 is available on the logical channel identified in step S22. If it is determined that the application identified in step S23 is not available on the logical channel identified in step S22 (step S26: NO), error processing is performed in the same manner as in step S4 above (step S27).

[0038] On the other hand, if it is determined that the application specified in step S23 is available on the logical channel specified in step S22 (step S26: YES), the process proceeds to step S28. In step S28, the CPU 21 opens the logical channel specified in step S22 and advances the process to step S29. If the basic logical channel has already been opened, the process of step S28 is skipped and the process proceeds to step S29.

[0039] In step S29, the CPU 21 selects the application specified in step S23. Next, the CPU 21 transmits a response APDU including status words SW1 and SW2 indicating normal termination to the external terminal via the operating interface (step S30). Such a response APDU may include FCI (File Control Information) regarding the file used by the selected application, and may further include the channel number of the opened logical channel.

[0040] As described above, according to the above embodiment, when the IC chip 2 receives a predetermined command from the external terminal via the operating interface, in response to the reception of the command, the IC chip 2 determines based on the management table TB1 whether the logical channel to be opened is available on the operating interface, and determines based on the management table TB2 whether the application to be selected is available on the logical channel to be opened. Then, when the IC chip 2 determines that the logical channel to be opened is available on the operating interface and the application to be selected is available on the logical channel to be opened, the IC chip 2 is configured to execute the process of opening the logical channel to be opened and selecting the application to be selected, so that incorrect use and unauthorized use of the IC card C can be prevented and convenience can be improved.

[0041] In the above-described embodiment, the IC card C having a contact communication interface and a non-contact communication interface has been described as an example. However, the present invention is applicable to an IC card having a plurality of contact communication interfaces. Further, in the above-described embodiment, the IC card C on which the IC chip 2 is mounted has been described as an example. However, the IC chip 2 of the present invention may be mounted on a small-sized IC card that is detachable from a communication device such as a smartphone, or may be mounted on an embedded substrate so that it cannot be easily removed or replaced from the communication device as an eUICC (Embedded Universal Integrated Circuit Card). In this case, the interface I / F1 of the IC chip 2 is connected to a CLF (ContactLess Front-end) provided in the communication device, and non-contact communication is performed with a non-contact reader / writer of, for example, a payment terminal T1 via the CLF. Note that communication between the interface I / F1 and the CLF is performed according to, for example, SWP.
