Description

  The present invention relates to an information processing apparatus, an information processing method, and a program.

  Conventionally, an IC (Integrated Circuit) card incorporating an integrated circuit capable of recording and calculating information has been put into practical use. Among them, an IC card, which is also called a smart card that includes a processor in an integrated circuit and realizes advanced information processing, has been widely used for various purposes in recent years as a settlement means and personal identification means in daily life.

  Information processing on an IC card is usually performed in response to a command given from an external device that can communicate with the IC card. There are various commands given to the IC card that cause the IC card to execute information input / output, computation, or security processing. Therefore, many IC cards developed in recent years have an operating system (hereinafter referred to as OS (Operating System)) as a base for executing such a group of instructions in a circuit. In order to enhance the versatility of the IC card by enabling the IC card to cooperate with a plurality of external devices according to different standards, there are cases where a plurality of types of OSs are mounted on the IC card.

  As a technique related to an IC card equipped with a plurality of OSs, for example, a technique described in Patent Document 1 below is known. For example, in Patent Document 1 below, processing corresponding to each message is performed even if the structure of a message passed between the case of communicating with an external device in a contact type and the case of performing a non-contact type communication are different. Techniques that enable this are disclosed.

JP 2005-242445 A

  By the way, in an IC card equipped with a plurality of OSs, there is a case where one OS wants to operate on the execution environment of another OS. For example, in an IC card equipped with a plurality of OSs such as Java (registered trademark) CardOS and FeliCa (registered trademark) OS, instead of installing FeliCaOS, an application imitating FeliCaOS is incorporated into Java CardOS, and FeliCaOS is installed in Java CardOS. You may want to run on the execution environment. When an application imitating FeliCaOS is executed on the execution environment of Java CardOS, the result of processing generated when FeliCaOS operates is equal. The application imitating the above-described FeliCaOS is controlled via the execution environment of the Java CardOS except for access control around the hardware originally managed by the OS, task scheduling function, encryption function, register setting, and the like. In this way, the file system management, command interpretation function, processing in accordance with command contents, response generation, and other functions are transformed into an executable form. If a virtual machine such as VMware (registered trademark) can be constructed on a card, the current OS can be installed as it is, and in this case, an application that imitates FeliCaOS indicates The meaning is synonymous with FeliCaOS that can operate on different execution environments.

  It should be noted that all functions in the OS are not limited to being ported in a complete form, but cases where limited functions or partial functions are provided are also included in the category of feasible forms indicated by this application. . In this case, since Java CardOS can add functions as an application later, FeliCaOS can be added later as needed. A partially imitated application can be added to or deleted from Java CardOS later as one service provision form, and various services can be replaced.

  However, as described above, when executing an application imitating FeliCaOS on the execution environment of Java CardOS, the execution environment on which FeliCaOS operates is different from the normal environment. Therefore, due to restrictions on the interface of Java CardOS, There is a problem that the transmission protocol and command format used cannot be used.

[Information processing apparatus according to the first embodiment of the present invention]
First, the information processing apparatus according to the first embodiment of the present invention will be described. FIG. 1 is a block diagram mainly showing a schematic configuration of the information processing apparatus according to the first embodiment of the present invention. In FIG. 1, an external device 200 and an information processing device 100 are depicted.

  In FIG. 1, an external device 200 is a communication device that can communicate with the information processing device 100. For example, the external apparatus 200 may be a reader / writer that reads and writes information recorded in the information processing apparatus 100. Further, the external device 200 may be an information processing device that provides a user with an arbitrary application using a function implemented in the information processing device 100.

  On the other hand, the information processing apparatus 100 is typically realized as a contact-type or non-contact-type IC card, IC chip, or the like. Further, the information processing apparatus 100 may be a communication module provided in an information communication terminal such as a mobile phone. As will be described later, the information processing apparatus 100 provides an instruction group for performing input / output of information recorded by the apparatus and various operations. Then, when a command is input from the external device 200, the information processing apparatus 100 executes a process corresponding to the command and outputs a response to the external device 200.

  The information processing apparatus 100 includes a communication unit 110 and an operating system (hereinafter referred to as “OS”) 120.

  The communication unit 110 is an example of a reception unit of the present invention, and is a communication interface that mediates communication between the information processing apparatus 100 and the external apparatus 200. Input of commands from the external apparatus 200 to the information processing apparatus 100 and output of responses from the information processing apparatus 100 to the external apparatus 200 are performed via the communication unit 110. For example, when the information processing apparatus 100 performs non-contact communication with the external apparatus 200, the communication unit 110 includes standards such as ISO / IEC14443 and ISO / IEC18092 (also known as NFC (Near Field Communication)). It can be realized as a communication interface according to a standard. Alternatively, when a communication interface such as NFC is realized as another device or module, the communication unit 110 serves as an interface for communicating with the device, and communicates with the external device 200 via the device. Become. For example, when the communication module goes out as CLF (Contact Less Front End), the communication unit 110 operates as a module for controlling an interface such as HCI / SWP defined by ETSI (European Telecommunications Standards Institute).

  The OS 120 performs input / output of information included in the information processing apparatus 100 and predetermined calculation in accordance with the input command. In this specification, a set of instructions that can be executed by the information processing apparatus 100 is referred to as an instruction group. For example, the OS 120 may be a Java Card (registered trademark) OS. For example, Java CardOS is an example of the first operating system of the present invention.

  The OS 120 includes an execution environment 130, an application A 150, an application B 160, and an application C 170.

  The execution environment 130 is a software group serving as a base for the OS 120 to execute a command group. The execution environment 130 mainly includes a packet interpretation unit 132, an application selection command generation unit 134, a command processing unit 136, and a storage unit 138. The instruction processing unit 136 mainly includes an instruction execution unit 140 and an application selection unit 142.

  When the communication packet received by the communication unit 110 is input, the packet interpretation unit 132 interprets the content of the communication packet and identifies the type of instruction for the OS 120 included in the communication packet. The types of commands include, for example, an information acquisition command for detecting a card equipped with FeliCaOS and acquiring information from the OS, an application selection command for selecting an application executed by the OS 120, and other commands. At this time, the command included in the communication packet may be stored in a temporary storage unit (not shown).

  FIG. 2 is an explanatory diagram showing an example of a format of an information acquisition command received by the information processing apparatus 100 in FIG. In FIG. 2, the information acquisition command 300 includes command information 302 and area information 304. The instruction information 302 includes, for example, an instruction code for identifying the type of instruction, a parameter for executing the instruction, and the like. On the other hand, the area information 304 includes, for example, information on an area for identifying a predetermined memory area held by FeliCaOS or an application imitating FeliCaOS.

  The packet interpretation unit 132 is an example of a determination unit according to the present invention. For example, when the command received from the external device 200 is identified as the information acquisition command 300 with reference to the command code included in the command information 302, The command is input to the application selection command generation unit 134. On the other hand, when the packet interpretation unit 132 identifies that the command received from the external device 200 is an application selection command or other commands, these commands are input to the command processing unit 136. If the packet interpretation unit 132 identifies that the command received from the external device 200 is an application selection command, the packet interpretation unit 132 inputs this command to the application selection unit 142 of the command processing unit 136. Then, when a response corresponding to the above-described command is output from the command processing unit 136, the packet interpretation unit 132 transmits the response to the external device 200 via the communication unit 110.

  When the information acquisition command 300 is input by the packet interpretation unit 132, the application selection command generation unit 134 reads the table TBL1 in which the region information and the application identification information as illustrated in FIG. 4A are associated from the storage unit 138. Then, the application selection command generation unit 134 refers to the read table TBL1 to determine application identification information associated with the region information 304 included in the input information acquisition command 300. For example, when the area information 304 included in the information acquisition command 300 is “AAAAA”, “0001” is determined as the application identification information. In the present embodiment, it is assumed that the application identification information corresponding to the application A 150 is “0001”. The application identification information is information for identifying an application managed by the OS 120 such as Java CardOS. After determining the application identification information, the application selection command generation unit 134 generates an application selection command 350 for selecting an application executed by the OS 120 as shown in FIG. The application selection command generation unit 134 inputs the generated application selection command 350 to the application selection unit 142 of the command processing unit 136.

  As shown in FIG. 4B, when the response availability flag corresponding to the region information 304 is given to the TBL 1 B, the application selection command generation unit 134 associates from the region information 304 if the “response impossible” flag is set. It is determined that the process for determining the received application identification information is not necessary, and no response or an error with respect to the command received from the external device 200 is returned to the external device. When the “response possible” flag is set, the application selection command 350 is generated as described above, and the command is passed to the application selection unit 142.

  FIG. 3 is an explanatory diagram showing an example of a format of an application selection command input to the command processing unit 136 of the information processing apparatus 100 in FIG. In FIG. 3, the application selection command 350 includes command information 352 and application identification information 354. The instruction information 352 includes, for example, an instruction code for identifying the type of instruction, a parameter for executing the instruction, and the like. On the other hand, the application identification information 354 includes identification information of an application executed by the OS 120. The above format imitates an instruction passed from an external device as an application selection instruction. However, if the application selection unit 142 has already interpreted the above information by breaking it down into elements, input it according to the form. May be. In that case, there is no instruction code, and parameter passing for an interface between modules such as an API is an example.

The instruction processing unit 136 mainly includes an instruction execution unit 140 and an application selection unit 142. The instruction execution unit 140 executes instructions other than the application selection instruction 350 input to the instruction processing unit 136. The application selection unit 142 is an example of the execution unit of the present invention, and executes the application selection command 350 input to the command processing unit 136. For example, the application selection unit 142 reads the table TBL2 in which the application identification information and the application storage area as illustrated in FIG. TBL2 is a table that manages the application identification information managed by the OS 120 such as Java CardOS and the storage area in association with each other. This management method is an example, and is not necessarily a table. It is also assumed that the application storage area is managed by repeating the end point. Then, the application selection unit 142 refers to the read table TBL2, and determines the application storage area associated with the application identification information 354 included in the input application selection instruction 350. For example, if the application identification information 354 included in the application selection instruction 350 is “0001”, an application executable program can be specified by specifying “0 to 1000”, that is, the memory address where the application A 150 is stored. Is determined. This memory address is Java
Relative addresses that are numbered by logically interpreting the memory managed by CardOS are assumed, but when the OS directly manages using physical addresses, the identifier and address of the physical memory There is no problem even if an absolute address such as is adopted. After determining the executable program of the application, the instruction execution unit 140 executes the determined executable program of the application. The command processing unit 136 outputs a response to the command executed by the command execution unit 140 or the application selection unit 142 to the packet interpretation unit 132.

  The response availability flag for the region information described in FIG. 4B can be set as “response possible” or “response impossible” from the executable program, and the setting contents vary depending on the state of the executable program. .

  When the application is in a non-selected state or when the card power is turned off, the flag cannot be set from the application. In this case, the default value is set or the value is initialized by the OS.

  In the flag setting flow, all flags are initialized when the OS is started, the flag is set by the selected executable program, and when the executable program is in a non-selected state, the OS re-initializes the corresponding flag. To implement.

  When the OS re-initializes the flag, the OS knows the non-selected executable program. Therefore, the application identification information is extracted from the OS, the area information is calculated from the application identification information, and the response availability flag corresponding to the area information is obtained. It becomes a flow to re-initialize.

  Application A150, application B160, and application C170 are arbitrary applications that operate on the OS 120. In the present embodiment, the application A 150 is an application imitating, for example, a FeliCa (registered trademark) OS. When the application A150 is executed on the execution environment 130 of the OS 120, the processing result generated when the FeliCaOS operates is equal. For example, FeliCaOS is an example of the second operating system of the present invention. Here, the term “application” includes applets and software including only simple logic.

[Information processing]
Hereinafter, information processing executed by the information processing apparatus 100 in FIG. 1 will be described. FIG. 6 is a flowchart of information processing executed by the information processing apparatus 100 in FIG.

  In FIG. 6, first, the communication unit 110 of the information processing device 100 receives a communication packet from the external device 200 (step S <b> 602), and transmits the received communication packet to the packet interpretation unit 132.

  Next, the packet interpretation unit 132 of the information processing apparatus 100 interprets the communication packet received from the communication unit 110 (step S604). Then, the packet interpretation unit 132 of the information processing apparatus 100 determines whether or not the command included in the communication packet is the above-described information acquisition command based on the interpretation of the communication packet in Step S604 (Step S606).

  As a result of the determination in step S606, when the command included in the communication packet is an information acquisition command (YES in step S606), the packet interpretation unit 132 of the information processing device 100 selects the information acquisition command as an application selection of the information processing device 100. This is input to the instruction generation unit 134. The application selection command generation unit 134 of the information processing apparatus 100 reads the table TBL1A shown in FIG. 4A from the storage unit 138 (step S608), and obtains application identification information associated with the region information included in the input information acquisition command. The application selection command shown in FIG. 3 is generated (step S610). Then, the application selection command generation unit 134 inputs the application selection command generated in step S610 to the application selection unit 142 in the command processing unit 136 of the information processing apparatus 100, and proceeds to the process of step S612.

  On the other hand, as a result of the determination in step S606, when the instruction included in the communication packet is not an information acquisition instruction (NO in step S606), the packet interpretation unit 132 of the information processing apparatus 100 determines that the instruction included in the communication packet is the application described above. It is determined whether or not it is a selection command (step S618).

  As a result of the determination in step S618, when the instruction included in the communication packet is an application selection instruction (YES in step S618), the packet interpretation unit 132 of the information processing apparatus 100 converts the application selection instruction into the instruction processing of the information processing apparatus 100. The application is input to the application selection unit 142 in the unit 136, and the process proceeds to step S612.

  In the subsequent process of step S612, the application selection unit 142 of the information processing apparatus 100 executes the input application selection command and selectively executes the application (step S612). For example, the application selection unit 142 of the information processing apparatus 100 reads the table TBL2 illustrated in FIG. 5 from the storage unit 138 and executes an application corresponding to the application identification information included in the input application selection command. In the present embodiment, the application A150 is an application imitating FeliCaOS, and when executed on the execution environment 130 of the OS 120, the processing result generated when the FeliCaOS operates is equal. Then, the process proceeds to step S614.

  On the other hand, as a result of the determination in step S618, when the instruction included in the communication packet is not an application selection instruction (NO in step S618), the packet interpretation unit 132 of the information processing apparatus 100 sends another instruction to the information processing apparatus 100 instruction. The data is input to the instruction execution unit 140 in the processing unit 136.

  Next, the instruction execution unit 140 of the information processing apparatus 100 executes the other input instruction (step S620), and proceeds to the process of step S614.

  In the subsequent process of step S614, the instruction processing unit 136 of the information processing apparatus 100 generates a response including the execution result of the instruction executed by the instruction execution unit 140 or the application selection unit 142 (step S614). Then, the instruction processing unit 136 of the information processing apparatus 100 inputs the response generated in step S614 to the packet interpretation unit 132 of the information processing apparatus 100.

  Next, the packet interpretation unit 132 of the information processing device 100 transmits the input response to the external device 200 via the communication unit 110 (step S616), and ends this process.

  According to the information processing of FIG. 6, when an instruction included in a communication packet is an information acquisition instruction, an application selection instruction including application identification information associated with area information included in the information acquisition instruction is generated and generated. The application is selectively executed by executing the selected application selection command. For example, in the information processing apparatus 100, when the application A150 imitating FeliCaOS is incorporated into the OS 120 instead of installing FeliCaOS, the transmission protocol and command format used in the normal FeliCaOS cannot be used. However, the information acquisition command usually corresponds to the transmission protocol used in FeliCaOS. When the application A150 imitating FeliCaOS is selected by the above-described information processing and executed on the execution environment 130 of the OS 120, the processing result generated when the FeliCaOS operates is equal. Accordingly, it is possible to cause the application from the external apparatus 200 to be executed for an application imitating an OS that operates in an execution environment different from the normal without changing the specification of the instruction from the external apparatus 200.

[Information processing apparatus according to the second embodiment of the present invention]
The information processing apparatus according to the second embodiment of the present invention will be described below. The information processing apparatus according to the second embodiment of the present invention does not have an application selection instruction generation unit as compared with the information processing apparatus according to the first embodiment of the present invention described above. Is different. In the following, the information processing apparatus according to the second embodiment of the present invention will be described mainly with respect to differences from the information processing apparatus according to the first embodiment of the present invention, and the first embodiment of the present invention will be described. Detailed description of the same configuration as that of the information processing apparatus according to the embodiment will be omitted. FIG. 7 is a block diagram mainly showing a schematic configuration of the information processing apparatus according to the second embodiment of the present invention. In FIG. 7, the external device 500 and the information processing device 400 are depicted.

  In FIG. 7, the information processing apparatus 400 includes a communication unit 410 and an OS 420. The OS 420 includes an execution environment 430, an application A 450, an application B 460, and an application C 470. The communication unit 410 is an example of a receiving unit of the present invention. The execution environment 430 mainly includes a packet interpretation unit 432, an instruction processing unit 436, and a storage unit 438. The instruction processing unit 436 mainly includes an instruction execution unit 440 and an application selection unit 442.

  The packet interpretation unit 432 is an example of a determination unit of the present invention. When a communication packet received by the communication unit 410 is input, the packet interpretation unit 432 interprets the content of the communication packet and identifies the type of instruction to the OS 420 included in the communication packet. To do. Further, when the packet interpretation unit 432 identifies that the command received from the external device 500 is an information acquisition command or an application selection command, the packet interpretation unit 432 inputs these commands to the application selection unit 442 in the command processing unit 436. On the other hand, when the packet interpretation unit 432 identifies that the command received from the external device 500 is another command, the packet interpretation unit 432 inputs this command to the command execution unit 440 in the command processing unit 436. Then, when a response corresponding to the above-described command is output from the command processing unit 436, the packet interpretation unit 432 transmits the response to the external device 500 via the communication unit 410.

  The instruction processing unit 436 mainly includes an instruction execution unit 440 and an application selection unit 442. The instruction execution unit 440 executes other input instructions. The application selection unit 442 is an example of the execution unit of the present invention, and executes an information acquisition command or an application selection command input to the command processing unit 436. For example, in the execution of the information acquisition command, the application selection unit 442 reads the table TBL1A in which the area information and the application are associated with each other as illustrated in FIG. 4A from the storage unit 438. Then, the application selection unit 442 refers to the read table TBL1A to determine application identification information associated with the area information included in the input information acquisition command. For example, when the area information included in the information acquisition command is “AAAA”, it is determined as application identification information executed by “0001”. After determining the application identification information, the application selection unit 442 calls the determined application using the specified application identification information. The application selection unit 442 uses TBL2 as shown in FIG. 5 to determine the application storage location from the application identification information. The command processing unit 436 outputs a response to the command executed by the command execution unit 440 or the application selection unit 442 to the packet interpretation unit 432.

  An application A 450, an application B 460, and an application C 470 are arbitrary applications that operate on the OS 420. In the present embodiment, the application A 450 is an application imitating, for example, a FeliCa (registered trademark) OS. When the application A 450 is executed on the execution environment 430 of the OS 420, the processing result generated when the FeliCaOS operates is equal.

[Information processing]
Hereinafter, information processing executed by the information processing apparatus 400 in FIG. 7 will be described. FIG. 8 is a flowchart of information processing executed by the information processing apparatus 400 in FIG.

  In FIG. 8, first, the communication unit 410 of the information processing device 400 receives a communication packet from the external device 500 (step S <b> 902), and transmits the received communication packet to the packet interpretation unit 432.

  Next, the packet interpretation unit 432 of the information processing apparatus 400 interprets the communication packet received from the communication unit 410 (step S904). Then, the packet interpretation unit 432 of the information processing apparatus 400 determines whether or not the instruction included in the communication packet is the above-described information acquisition instruction based on the interpretation of the communication packet in Step S904 (Step S906).

  As a result of the determination in step S906, when the command included in the communication packet is an information acquisition command (YES in step S906), the packet interpretation unit 432 of the information processing device 400 converts the information acquisition command into the command processing of the information processing device 400. The data is input to the application selection unit 442 in the unit 436. The application selection unit 442 of the information processing apparatus 100 reads the tables TBL1A and 2 shown in FIGS. 4A and 5 from the storage unit 438 (step S908), and proceeds to the process of step S910.

  On the other hand, as a result of the determination in step S906, when the instruction included in the communication packet is not an information acquisition instruction (NO in step S906), the packet interpretation unit 432 of the information processing apparatus 400 indicates that the instruction included in the communication packet is the application described above. It is determined whether or not it is a selection command (step S916).

  As a result of the determination in step S916, when the instruction included in the communication packet is an application selection instruction (YES in step S916), the packet interpretation unit 432 of the information processing apparatus 400 outputs the application selection instruction to the instruction processing of the information processing apparatus 400. The information is input to the application selection unit 442 in the unit 436, and the process proceeds to step S910.

  In the subsequent process of step S910, the application selection unit 442 of the information processing apparatus 400 executes the input information acquisition command or application selection command to selectively execute the application (step S910). For example, when an information acquisition command is input, the application selection unit 442 of the information processing apparatus 400 refers to the table TBL1A, 2 read in step S908 and corresponds to the region information included in the input information acquisition command. Run the application. In the present embodiment, the application A 450 is an application imitating FeliCaOS, and when executed on the execution environment 430 of the OS 420, the processing result generated when the FeliCaOS operates is equal. Then, the process proceeds to step S912.

  On the other hand, as a result of the determination in step S916, when the instruction included in the communication packet is not an application selection instruction (NO in step S916), the packet interpretation unit 432 of the information processing apparatus 400 sends another instruction to the information processing apparatus 400 instruction. The data is input to the instruction execution unit 440 in the processing unit 436.

  Next, the instruction execution unit 440 of the information processing apparatus 400 executes the other input instruction (step S918), and proceeds to the process of step S912.

  In the subsequent process of step S912, the instruction processing unit 436 of the information processing device 400 generates a response including the execution result of the instruction executed by the instruction execution unit 440 or the application selection unit 442 (step S912). Then, the instruction processing unit 436 of the information processing device 400 inputs the response generated in step S912 to the packet interpretation unit 432 of the information processing device 400.

  Next, the packet interpretation unit 432 of the information processing device 400 transmits the input response to the external device 500 via the communication unit 410 (step S914), and ends this process.

  According to the information processing of FIG. 8, when an instruction included in a communication packet is an information acquisition instruction, an application corresponding to the area information included in the information acquisition instruction is selectively executed in order to execute the information acquisition instruction. . Thereby, the same effect as the information processing of FIG. 6 described above can be obtained. In addition, the information processing apparatus 400 in FIG. 7 does not include the application selection command generation unit 134 as compared with the information processing apparatus 100 in FIG.

[Modification of information processing apparatus according to each embodiment of the present invention]
Hereinafter, modified examples of the information processing apparatuses 100 and 400 according to the embodiments of the present invention will be described. FIG. 9 is a block diagram mainly showing a schematic configuration of a modified example of the information processing apparatuses 100 and 400 according to the respective embodiments of the present invention. In FIG. 9, external devices 100 and 500 and information processing devices 100 and 400 are depicted.

  In FIG. 9, the information processing apparatuses 100 and 400 include communication units 110 and 410 and OSs 120 and 420. The OSs 120 and 420 include execution environments 130 and 430, applications A 150 and 450, applications B 160 and 460, and applications C 170 and 470. The execution environments 130 and 430 mainly include packet interpretation units 132 and 432, a format check unit 600, and instruction processing units 136 and 436.

  When the communication packets received by the communication units 110 and 410 are input, the packet interpretation units 132 and 432 interpret the contents of the communication packets and identify the types of instructions for the OSs 120 and 420 included in the communication packets. Then, the packet interpretation units 132 and 432 input the commands received from the external devices 200 and 500 to the format check unit 600. The format check unit 600 checks the format of instructions input from the packet interpretation units 132 and 432. Then, as a result of checking the format of the instruction, the format check unit 600 inputs the instruction to the instruction processing units 136 and 436 when the instruction has a predetermined format. The instruction processing units 136 and 436 execute the instruction input from the format check unit 600.

[Format check processing]
The format check process executed by the information processing apparatus in FIG. 9 will be described below. FIG. 10 is a flowchart of the format check process executed by the information processing apparatuses 100 and 400 in FIG. This processing is processing for checking the format of the communication packet received from the external device 200 or 600 when the information processing device 100 or 400 executes the information processing of FIG. 6 or FIG. This process is a process executed by the format check unit 600 of the information processing apparatuses 100 and 400.

  10, first, the format check unit 600 of the information processing devices 100 and 400 executes the information processing of FIG. 6 or 8 described above, and as a result, whether the applications A 150 and 450 are selected in the information processing devices 100 and 400. It is determined whether or not (step S1102).

  If it is determined in step S1102 that the applications A150 and 450 are selected in the information processing apparatuses 100 and 400 (YES in step S1102), the format check unit 600 of the information processing apparatuses 100 and 400 checks the format of the instruction. Is stopped, that is, all instructions are input to the instruction processing units 136 and 436 (step S1104), and this process is terminated.

  On the other hand, as a result of the determination in step S1102, when the applications A 150 and 450 are not selected in the information processing apparatuses 100 and 400 (NO in step S1102), the format check unit 600 of the information processing apparatuses 100 and 400 displays the instruction format. When the instruction is in a predetermined format, the instruction is input to the instruction processing units 136 and 436 (step S1106), and the process is terminated.

  According to the format check process of FIG. 10, when the applications A 150 and 450 are selected in the information processing apparatuses 100 and 400, the check of the instruction format in the format check unit 600 is stopped. As described above, the applications A150 and 450 are applications imitating FeliCaOS, and when operated on the execution environments 130 and 430 of the OSs 120 and 420, the processing results generated when the FeliCaOS operates are equal. Since the instructions input to Java CardOS and the instructions input to FeliCaOS have different formats, the instruction input to FeliCaOS is changed by stopping the format check of the instruction in format check unit 600. It can be surely passed to an application imitating FeliCaOS.

  In the format check process of FIG. 10, whether or not the format check is necessary is determined according to the application selection state, but whether or not the format check is necessary is determined depending on the form in which the communication units 110 and 410 receive the command. It is also possible to judge.

  The communication units 110 and 410 have various contactless communication functions such as NFC, when communicating with an external device, or when another device or chip is connected to the communication unit and receives a command therefrom. Therefore, it is possible to determine whether or not a format check is necessary according to the path.

[Other format check processing]
Hereinafter, another format check process executed by the information processing apparatus in FIG. 9 will be described. FIG. 11 is a flowchart of another format check process executed by the information processing apparatuses 100 and 400 in FIG. This processing is processing for checking the format of the communication packet received from the external device 200 or 600 when the information processing device 100 or 400 executes the information processing of FIG. 6 or FIG. This process is a process executed by the format check unit 600 of the information processing apparatuses 100 and 400.

  11, first, the format check unit 600 of the information processing devices 100 and 400 executes the information processing of FIG. 6 or 8 described above, and as a result, the communication protocol in the information processing devices 100 and 400 is a predetermined communication protocol. Whether or not (step S1202).

  If the result of determination in step S1202 is that the communication protocol in the information processing apparatus 100, 400 is a predetermined communication protocol (YES in step S1202), the format check unit 600 of the information processing apparatus 100, 400 checks the format of the instruction. Is stopped, that is, all instructions are input to the instruction processing units 136 and 436 (step S1204), and this process ends.

  On the other hand, if the result of determination in step S1202 is that the communication protocol in information processing apparatuses 100 and 400 is not a predetermined communication protocol (NO in step S1202), format check unit 600 of information processing apparatuses 100 and 400 determines the format of the instruction. When the check is performed and the instruction is in a predetermined format, the instruction is input to the instruction processing units 136 and 436 (step S1206), and this process is terminated.

  According to the format check process of FIG. 11, when the communication protocol in the information processing apparatuses 100 and 400 is a predetermined communication protocol, the check of the format of the instruction in the format check unit 600 is stopped. As described above, the applications A150 and 450 are applications imitating FeliCaOS, and when operated on the execution environments 130 and 430 of the OSs 120 and 420, the processing results generated when the FeliCaOS operates are equal. Since the instructions input to Java CardOS and the instructions input to FeliCaOS have different formats, the instruction input to FeliCaOS is changed by stopping the format check of the instruction in format check unit 600. , It can be reliably passed to an application imitating FeliCaOS.

The nonvolatile memory 908 is an EEPROM (Electrically Erasable and Programmable ROM) or the like, and can store an application added later.

  The CPU 902, ROM 904, RAM 906, and nonvolatile memory 908 are connected to each other via a bus 910. An input / output interface 912 is further connected to the bus 910.

  The CPU 902 is connected to the ROM 904, the RAM 906, and the nonvolatile memory 908, so that the packet interpretation units 132 and 432, the application selection command generation unit 134, the command processing units 136 and 436, the application selection units 142 and 442, and the command execution described above. Functions as the units 140 and 440. The communication circuit 914 functions as the communication units 110 and 410.
