Example 1
Fig. 1 shows a schematic flow chart of a data calling method provided by the application, which can be applied to a security chip by way of example and not limitation.
S101, receiving a call command sent by an application chip, wherein the call command comprises a function name and parameters of a target call function;
In a specific application, a call command sent by an application chip (Application processor, AP) is received. The call command is sent by the application chip and is used for controlling the security chip (Security processor, SP) to call the system according to the target call function. The call command should include, but is not limited to, a function name and parameters of the target call function. The function name may be a character string, for example, the function name of the target call function may be rpc _open, rpc_ioctl, rpc_close, or read.
For example, if a call of the data reading function is required, the call command sent by the application chip should include the name read of the data reading function and the parameter of the data reading function.
S102, analyzing the call command to obtain the function name included in the call command;
In a specific application, analyzing the received call command to obtain the function name of the target call function contained in the call command so as to determine the target call function.
S103, performing system call through the target call function to obtain a call result, and feeding back the call result to the application chip, wherein the call result comprises a function call result and an error code.
In a specific application, further analyzing to obtain parameters of a target calling function in a calling command, transmitting the parameters into the target calling function to realize system calling through the target calling function, obtaining a function calling result corresponding to the target calling function, packaging the function calling result and an error code, generating a calling result and transmitting the calling result to an application chip. It is understood that call results include, but are not limited to, function call results and error codes.
For example, if the target calling function is a data reading function (read), the data reading function performs a data reading operation, packages the read data and the error code, generates a calling result, and sends the calling result to the application chip.
Wherein the error code is a code generated when a system call is made through the target call function with errors. It can be appreciated that if the system call is successful by the target call function, the corresponding error code is 0 or null. If the system call fails through the target call function, the corresponding function call result is null.
In one embodiment, before the step S101, the method includes:
and presetting a communication protocol between the application chip and the communication protocol, wherein the communication protocol is used for setting the format of the calling command.
In a specific application, before the system call is performed, a communication protocol between the security chip and the application chip can be preset, and the communication protocol is used for setting a format of the application chip for sending the call command.
In this embodiment, the communication protocol specifies that the call command transmitted from the application chip must include a protocol header, a function name (in the form of a string) of the target call function, and parameters of the target call function. For example, the call command is in the format of a protocol header, a function name, and parameters.
In one embodiment, the communication protocol is also used to format the call results sent by the secure chip. For example, the call result sent by the communication protocol to the security chip must include a protocol header, a function call result and an error code, for example, the call result is in the format of the protocol header, the function call result and the error code. After the system call is performed through the target call function, the security chip needs to package the protocol header, the function call result and the error code to generate the call result.
In one embodiment, before the step S101, the method further includes:
When receiving a registration notification instruction sent by the application chip, completing registration notification according to the registration notification instruction;
when the trigger data is detected, generating a notification according to the trigger data, and sending the notification to the application chip, wherein the notification is used for notifying the application chip that the trigger data is detected at the security chip end.
In a specific application, when a registration notification instruction sent by an application chip is received, registration notification is performed according to the registration passing instruction, and when trigger data is detected, a corresponding notification is generated according to the trigger data and sent to the application chip. The registration notification refers to a mode of generating a corresponding notification according to the trigger data when the trigger data is received, and the notification is used for notifying an application chip that the trigger data is detected at a security chip end. The trigger data may be key information detected at the security chip, data triggering operations of different functions such as IC card insertion or IC card extraction, and the like.
For example, if the security chip detects an IC card insertion, an IC card insertion notification is generated from the data of the IC card insertion, and the IC card insertion notification is sent to the application chip to notify the application chip that the insertion of the IC card is detected at the security chip side. The IC card insertion data may include information such as a time of IC card insertion, an ID of the IC card, and the like.
According to the call instruction carrying the function name of the target function, the system call is carried out in the target function, so that the application chip can directly obtain the data call result of the security chip, the inter-chip system call is realized, and the data processing efficiency of the system is improved.
Example two
Fig. 2 shows another schematic flow chart of the data calling method provided by the present application, which can be applied to an application chip by way of example and not limitation.
S201, sending a calling command to a security chip so that the security chip can carry out system call according to the protocol data, wherein the calling command comprises a function name and parameters of a target calling function;
In a specific application, when an application chip generates a call command, firstly, a preset interface of unified encapsulation in a POS SDK library call library is used for encapsulating a protocol header, a function name and parameters of a target call function through the interface, so as to generate a corresponding call command, and the call command is sent to a security chip, so that the security chip can perform system call of the target call function according to protocol data. The preset interface of the unified package may be specifically set according to actual requirements, for example, the preset interface of the unified package is any one of open interfaces (for example, xxx_open () interface).
S202, receiving and analyzing a calling result returned by the security chip to obtain an analyzed function calling result, wherein the calling result comprises a function calling result and an error code.
In a specific application, a call result returned by the security chip is received, the call result is analyzed, and an analyzed function call result is obtained, wherein the call result comprises, but is not limited to, a function call result and an error code. The error code is a code generated when a system call is made through the target call function with errors. It can be appreciated that if the system call is successful by the target call function, the corresponding error code is 0 or null. If the system call fails through the target call function, the function call result is null.
For example, if the target calling function is a data reading function read, the calling result includes the read data and the error code.
In one embodiment, before the step 201, the method includes:
Sending a registration notification instruction to the security chip so that the security chip carries out registration notification according to the registration notification instruction;
And starting a monitoring mode, and generating a corresponding calling command according to the notification when the notification sent by the security chip is monitored.
In a specific application, a registration notification instruction is sent to the security chip, so that the security chip carries out registration notification according to the registration notification instruction when receiving the registration notification instruction, when the security chip detects trigger data, corresponding notification is generated and fed back, a select monitoring mode is started, and when the notification sent by the security chip is monitored, a corresponding calling command is generated according to the notification.
For example, if the IC card insertion is detected in the security chip, a data read call command (which includes the name read of the data read function and the parameter of the data read function) is generated and sent to the security chip to control the security chip to perform the data read operation according to the data read function (read) included in the data read call command.
In one embodiment, before the step 201, the method further includes:
and creating a socket interface, wherein the socket interface is used for receiving the calling result and the notification.
In a specific application, a socket interface is created in advance, and the socket interface is used for receiving a calling result and a notification sent by the security chip.
As shown in fig. 3, a schematic diagram of a data transmission software framework between an application chip and a security chip is provided.
As shown in fig. 3, an inter-process communication layer based on SOCKET (SOCKET) is added between the POS SDK and the universal asynchronous receiver Transmitter (Universal Asynchronous Receiver/Transmitter, UART) to implement multi-client connection and data transmission.
Before the application chip sends the registration notification, an open function (open) call command can be sent to the security chip, wherein the open interface (for example, xxx_open interface) preset in the POS SDK is called through the application program layer, the open function (open) call command is sent to the security chip through the preset open interface, the security chip executes system call in the open function rpc _open, and after the security chip executes the open function system call, sp_fd is returned to the preset open interface, so that the open function system call is successful, and the open access function is realized.
After the open function system call is successful, the application chip can create a pair of interconnected sockets (the sockets can be nameless sockets, which are convenient for transmitting data), and the sockets comprise a read handle sv [0] and a write handle sv [1]. When the application chip sends a registration notification command to the security chip, a monitoring thread is created, a write handle sv [1] is used as a parameter to be transmitted into the thread, meanwhile, a read-write handle of a select monitoring socket client is called, and a read handle sv [0] is sent to the application program layer, so that the application program layer adds the read handle sv [0] into the select monitoring;
When the application chip side monitors that the socket receives the notification sent by the security chip through the selection, the application chip side reads data in the notification, and writes 1 byte of data in the write handle sv [1] to wake up the selection monitoring of the application program layer. When the application program monitors the notification received by the socket read handle sv [0] through the select, any data read interface (for example, xxx_read) of the POS SDK is called to read the data in the write handle sv [1], a corresponding data read call command is generated according to the data contained in the notification, and the data read call command is sent to the security chip to carry out system call. And meanwhile, the socket service is connected, when the UART receives a call result fed back by the SP, the call result is sent to a corresponding socket client and is sent to the POS SDK, the POS SDK analyzes the call result, and the function call result and the error code obtained after analysis are returned to the application program layer, so that the function of the double-processor compatible single-processor selection is realized, and the data transmission efficiency between the double chips is improved.
According to the call instruction carrying the function name of the target function, the system call is carried out in the target function, so that the application chip can directly obtain the data call result of the security chip, the inter-chip system call is realized, and the data processing efficiency of the system is improved.
It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic, and should not limit the implementation process of the embodiment of the present application.
