Based on the foregoing technical solutions provided in the present application, the following details of the technical solutions are described, and as shown in fig. 2, a specific process flow diagram of one possible implementation manner of a method for automatically matching application programs on a multi-application device provided in the present application is shown.
For the present application, a default application is currently set on the multi-application device, and in one possible implementation, the foregoing processing of step S101 specifically includes the processing of step S201 described below.
In step S201, the multi-application device receives an application program instruction.
In one possible implementation, for an input application program instruction, the multi-application device receives the application program instruction through a corresponding interface. The interface may include two interfaces, i.e., an HID interface and a CCID interface, and different application program instructions are input to the multi-application device through the corresponding interfaces.
For the present application, in one possible implementation, the foregoing processing of step S102 specifically includes the following processing of step S202 to step S203.
In step S202, the multi-application device determines the interface type of the interface outputting the application program instruction.
In one possible implementation, the multi-application device determines the interface type of the interface outputting the application program instruction after receiving the application program instruction through the interface. In this case, since the multi-application device is provided with the two interfaces for receiving the application program command, it is easy to determine which interface outputs the application program command.
In step S203, the multi-application device determines whether the protocol type corresponding to the application program instruction is a specific protocol type based on the interface type.
In one possible implementation, based on a preconfigured definition of a specific protocol type, the HID protocol type corresponding to the HID interface is a specific protocol type, and the CCID protocol type corresponding to the CCID interface is a non-specific protocol type. Therefore, after determining the interface type, the multi-application device can well distinguish whether the protocol type corresponding to the application program instruction is a specific protocol type according to the pre-configuration definition. When it is determined that the protocol type of the application program instruction is a specific protocol type (HID protocol type), the flow goes to step S204; when it is determined that the protocol type of the application instruction is the nonspecific protocol type (CCID protocol type), the flow goes to step S212.
For the present application, in one possible implementation, the foregoing processing of step S103 specifically includes the processing of step S204 described below.
In step S204, the multi-application device determines the instruction type corresponding to the application program instruction based on the specific byte in the application program instruction.
In one possible implementation manner, after determining that the protocol type of the application program instruction is a specific protocol type, further determining an instruction type corresponding to the application program instruction is needed, where for the instruction type, the determination may be performed according to a specific byte in the application program instruction, for example, a 5 th byte in the application program instruction, and certainly, the determination may not be limited to the 5 th byte, and any other byte capable of determining the instruction type may be used; when a specific byte in the application program instruction is a first specific byte, determining that the instruction type corresponding to the application program instruction is a first instruction type; and when the specific byte in the application program instruction is the second specific byte, determining the instruction type corresponding to the application program instruction as the second instruction type. For the above embodiment of the present application, the first instruction type is an instruction type of an MSG instruction, and the second instruction type is an instruction type of an INIT instruction.
In this embodiment, taking the 5 th byte as an example, when the 5 th byte of the application program instruction is 0x86, determining the instruction type corresponding to the application program instruction as an INIT instruction (FIDO initialization instruction); when the 5 th byte of the application program instruction is 0x83, determining the instruction type corresponding to the application program instruction as an MSG instruction; of course, the method is not limited to the two instruction types, and may include determining that the instruction type corresponding to the application program instruction is a CBOR instruction if the 5 th byte of the application program instruction is 0x 90; when the 5 th byte of the application program instruction is 0x91, the instruction type corresponding to the application program instruction is determined to be a CANCEL instruction and the like.
For the present application, in one possible implementation manner, the foregoing processing of step S104 specifically includes the following processing of step S205 to step S208. Wherein when it is determined that the instruction type is the first instruction type, the process goes to step S205, and when it is determined that the instruction type is the second instruction type, the process goes to step S209.
For the present application, in one possible implementation manner, for the foregoing processing of step S104, when the instruction type is the first instruction type, the following processing of step S205 to step S208 is specifically included; when the instruction type is the second instruction type, the processing of the following steps S209 to S210 is specifically included.
In step S205, the multi-application device determines whether the application program instruction carries the first command.
In one possible implementation, after determining that the instruction type is the MSG instruction of the first instruction type, it is further determined whether the application instruction carries the first command; if it is determined that the first command is carried, the process proceeds to step S206, otherwise, the process proceeds to step S213. The first command in the embodiment of the present application may refer to an APDU command. Wherein, for the mode of determining whether the first command is included in the application program instruction, whether the data length of the application program instruction is 0 can be determined; when the data length is not 0, the application program instruction includes the first command, and when the data length is 0, the application program instruction does not include the first command.
In step S206, the multi-application device determines whether the first command is a specific command.
In one possible implementation, after the multi-application device determines that the application program instruction carries the first command (APDU command) as described above, it needs to further determine whether the APDU command is a specific command, and when it is determined that the APDU command is a specific command, the process goes to step S207 to perform the processing, otherwise, goes to step S212 to perform the processing.
For an APDU command, the standard command format is 00a40400A0CAID, where 00a40400 represents the command header of the APDU, 0C represents the byte length of the application, ID represents the identity ID of the application, and a in A0C and AID represents the application; the APDU command may be various commands, such as GP standard selection command, PBOC command, PIV selection command, etc.; for the embodiments of the present application, the specific command determined above may refer to a GP standard selection command.
In step S207, the multi-application device extracts the identification information in the specific command.
In one possible implementation manner, for the GP standard selection instruction, where the specific instruction is the GP standard selection instruction, since the format of the GP standard selection instruction already includes the ID of the application, the multi-application device may directly extract the ID from the GP standard selection instruction.
In step S208, the multi-application device determines the application corresponding to the identification information as the target application.
In one possible implementation manner, after the multi-application device extracts the identity ID, directly determining an application program corresponding to the extracted identity ID as a target application program; after the target application is determined, the process proceeds to step S211 described below.
In one possible implementation manner, when the multi-application device determines that the instruction type corresponding to the application program instruction is the second instruction type, the processing in step S104 specifically goes to the processing in step S209 described below.
In step S209, the multi-application device queries the identity information base based on the instruction type.
In one possible implementation manner, when the instruction type is an INIT instruction of a second instruction type, the multi-application device needs to query a preset identity information base according to the instruction type, so as to determine whether target identity information matched with the instruction type is stored in the identity information base; when the target identity information matched with the instruction type is stored in the identity information base, the step S210 is shifted to; otherwise, when the target identification information matched with the instruction type is not stored in the identification information base, the process goes to step S213.
In step S210, the multi-application device determines that the application corresponding to the target identity information is the target application.
In one possible implementation, the multi-application device proceeds to step S211 after determining the target application.
For the present application, in one possible implementation, the foregoing processing of step S105 specifically includes the processing of step S211 described below.
In step S211, the multi-application device selects the target application as the current application on the multi-application device.
In one possible implementation, after determining the target application, the multi-application device may select the determined target application as the current application on the multi-application device. In this embodiment, even if the current application program on the multi-application device is the same application program as the determined target application program, the determined target application program is still used as the current application program on the multi-application device. After selecting the target application as the current application on the multi-application device, the process proceeds to step S212.
For the present application, in one possible implementation manner, the foregoing processing of step S106 specifically includes the processing of step S212 described below.
In step S212, the multi-application device sends the application program instruction to the current application program on the multi-application device for processing.
In one possible implementation, for the current application on the multi-application device to send the application instruction to the current application in this step for processing, two cases may be included:
(1) When the multi-application device determines that the protocol type of the application program instruction is a non-specific protocol type;
(2) When the multi-application device determines that the first command is a non-specific command;
(3) After the multi-application device takes the target application as the current application.
For the three cases, the application program instruction is given to the current application program on the multi-application device for processing, wherein (1) and (2) are direct application program instruction given to the current application program on the multi-application device, namely the current application program is not a definite target application program; (3) After determining the target application program and taking the determined target application program as the current application program on the multi-application device, an application program instruction is given to the current application program on the multi-application device.
In step S213, the multi-application device transmits an error notification message.
According to the method and the device, the purpose that the corresponding application programs are automatically compatible and matched on the multi-application device to process any application program instruction is achieved, and the processing efficiency is improved.
Based on the technical solution provided in the present application, the following is a detailed explanation of the technical solution, as shown in fig. 3, which is a process flow chart of a first embodiment of a method for automatically matching application programs on a multi-application device provided in the present application.
In this embodiment, two applications (a FIDO application and a PIV application) are installed on the multi-application device, wherein the FIDO application and the PIV application are applications that need to be selected by default. In this embodiment, the PIV application is taken as an example of a current application on a multi-application device.

In step S302, the multi-application device determines that the protocol type of the application program instruction is an HID protocol type.

In step S303, the multi-application device determines the corresponding instruction type according to the HID protocol type.
Optionally, after determining the HID protocol type, the multi-application device further determines an instruction type corresponding to the application program instruction according to byte 5 x86 in the application program instruction, and determines the instruction type to be an instruction type corresponding to an INIT instruction, where in this embodiment, the INIT instruction is FFFFFFFF 86 0004 01020304.
Step S304, the multi-application device queries corresponding target identity information according to the instruction type.
Optionally, after determining that the instruction type is the instruction type corresponding to the INIT instruction, since the INIT instruction is the FIDO initialization instruction, it may be determined that the target application is the FIDO application, so that the identity information matching the FIDO application needs to be found in the identity information library, that is, the multi-application device finds the target identity information corresponding to the instruction type of the INIT instruction by querying the built-in identity information library.
In step S305, the multi-application device selects the FIDO application as the current application according to the identification information of the FIDO.
Optionally, after obtaining the identifier information of the FIDO, the multi-application device determines a corresponding target application program FIDO application program according to the identifier information of the FIDO, so as to select the FIDO application program as a current application program on the multi-application device.
In step S306, the multi-application device sends a response message to the user that the replacement was successful.
In step S307, the multi-application device receives the FIDO other instruction sent by the user.
Alternatively, after selecting the current application as the FIDO application, the multi-application device may continue to receive other instructions of the FIDO and perform corresponding processing according to the received other instructions.
According to the method and the device, the purpose that the corresponding application programs are automatically compatible and matched on the multi-application device to process any application program instruction is achieved, and the processing efficiency is improved.
Based on the technical solution provided in the present application, the following is a detailed explanation of the technical solution, as shown in fig. 4, which is a process flow chart of a second embodiment of a method for automatically matching application programs on a multi-application device provided in the present application.
In this embodiment, two applications (a FIDO application and a PIV application) are installed on the multi-application device; the FIDO application and the PIV application are both applications requiring default selection. In this embodiment, the current application on the multi-application device is exemplified as the FIDO application.
In step S401, the multi-application device receives the application program instruction input through the HID interface.
Optionally, the multi-application device is currently in a standby state, and receives an application program instruction input through the HID interface.
In step S402, the multi-application device determines that the protocol type of the application program instruction is an HID protocol type.
Optionally, the multi-application device may determine, through the interface outputting the application program instruction, that the protocol type corresponding to the application program instruction is an HID protocol type.
In step S403, the multi-application device determines the corresponding instruction type according to the HID protocol type.
Optionally, after determining the HID protocol type, the multi-application device further determines an instruction type corresponding to the application program instruction according to byte 5 x83 in the application program instruction, and determines the instruction type to be an instruction type corresponding to an MSG instruction, where in this embodiment, the MSG instruction is 00000001 83 0004 80010000.
In step S404, the multi-application device determines that the application instruction is a PIV selection instruction.
Optionally, upon determining that the instruction type is an MSG instruction, the multi-application device further determines that the application instruction is a PIV select instruction 00a404000CA00000030800001000010000.
In step S405, the multi-application device extracts the identification information in the PIV selection instruction.
Optionally, after the multi-application device determines that the application program instruction is a PIV selection instruction, according to PIV selection instruction 00a404000CA00000030800001000010000, the identification information of the application program in the PIV selection instruction may be obtained as a00000030800001000010000.
