[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] A file data importing method provided in an embodiment of the present application can be applied to Figure 1 In the system architecture shown in Figure 1As shown, the system may include: a server and a terminal. The server may be a physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery networks (CDN), and basic cloud computing services such as big data and artificial intelligence platforms. The terminal may be a user equipment (UE) such as a mobile phone, smart phone, laptop, digital broadcast receiver, personal digital assistant (PDA), tablet computer (PAD), handheld device, vehicle-mounted device, wearable device, computing device or other processing device connected to a wireless modem, mobile station (MS), mobile terminal, etc. The terminal and the server may be directly or indirectly connected via wired or wireless communication, which is not limited in this application.

[0039] The terminal (device) is used to receive the import instruction information and send the import instruction information to the server.

[0040] The server is used to obtain import instruction information to execute a file data import method provided by the present application.

[0041] Generally, in actual application, the application of SE device (terminal device carrying smart card) imports file data through APDU instruction in online or offline scenarios. The user may mistakenly click repeatedly or retry due to network reasons. The APDU instruction script will be executed repeatedly, resulting in repeated import of file data into the terminal (hereinafter referred to as device).

[0042] Therefore, the present application provides a method for importing file data to solve the above-mentioned problems existing in the prior art and avoid repeated import of file data into a device.

[0043] The preferred embodiments of the present application are described below in conjunction with the drawings in the specification. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In addition, the embodiments and features in the embodiments of the present application may be combined with each other if there is no conflict.

[0044] Figure 2 A flowchart of a method for importing file data provided in an embodiment of the present application is shown below. Figure 2 As shown, the method may include:

[0045] Step S210: Obtain import instruction information.

[0046] The import instruction information includes the file data to be imported and the file data identifier.

[0047] Scenarios for obtaining import instruction information include:

[0048] After the card reader receives the signal including the initial file data sent by the device carrying the smart card, the card reader processes the initial file data to obtain processed file data, generates APDU instructions (import instruction information) for the processed file data, and sends the APDU instructions to the device that needs to carry the smart card.

[0049] Afterwards, the interface of the device receives the APDU instruction, searches the data field of the locally imported APDU instruction, and determines the position of the counter according to business rules; for example, the first 4 bytes of the data field of the first APDU in the APDU instruction searched for this business import, thereby determining the count value of the imported instruction information.

[0050] Furthermore, the structure of the import instruction corresponding to the import instruction information is: instruction category, instruction code, first instruction parameter (instruction parameter 1), second instruction parameter (instruction parameter 2), the number of bytes in the instruction data field, the data bit string sent by the instruction, and the maximum number of data bytes expected in the response data field.

[0051] The APDU instruction structure is shown in Table 1:

[0052] Table 1

[0053]

[0054]

[0055] Step S220: compare the count value corresponding to the import instruction information with the local count value corresponding to the file data to obtain a comparison result; and determine whether to execute the import instruction information based on the comparison result.

[0056] Before executing step S220, during the process of initializing the application of the device, a local count field is configured in the application smart card data, and the local count value is reflected in the field; the local count field is 4 bytes, and the initial value of the local count value is 00000000.

[0057] It should be noted that, when the file data in the import instruction information is imported into the device for the first time, the count value of the local count field corresponding to the file data is the initial value.

[0058] According to the file data identifier, the count value of the data field of the import instruction information is determined. It should be noted that the count field has a byte data structure in the data field corresponding to the import instruction, and the count value is reflected in the count field.

[0059] Step S220 specifically includes:

[0060] If the comparison result is that the difference between the count value and the local count value is 1, the import instruction information is executed. That is to say, when the count value is greater than the local count value and the difference between the two is 1, it indicates that the import instruction information can be executed. After executing the import instruction information, the local count value is updated to obtain the current local count value so that the current local count value is the same as the count value. In short, the local count value changes with each successful execution of the import instruction information.

[0061] For example, the count value of the local anti-replay count field is 00000000, and the count value of the count field corresponding to the import instruction information is 00000001, indicating that the import instruction information can be successfully executed.

[0062] If the comparison result is that the count value is not greater than the local count value, a response result including a count value error is generated or a response result including a repeated import is returned. In other words, when the count value is less than or equal to the local count value, the import instruction information cannot be successfully executed, and an error response result is returned. The application scenario at this time may be the repeated execution of the import instruction information caused by power outage or network disconnection. Therefore, the import instruction information cannot be successfully executed. This method can avoid the situation where the file data is repeatedly imported in abnormal scenarios, or the situation where the import cannot be normally imported due to errors.

[0063] For example, if the count value of the local count field is 00000002 and the count value of the count field in the import instruction information is 00000001 or 00000002, the import instruction information fails to be executed.

[0064] In some embodiments, if multiple import instruction information is obtained within a preset interval, a data import queue is generated according to the acquisition time of the import instruction information;

[0065] Repetitive file data in the data import queue are eliminated to obtain one or more import instruction information including non-repetitive file data and count values ​​corresponding to the non-repetitive file data;

[0066] According to the acquisition time of each import instruction information, the count value in the import instruction information is compared with the corresponding local count value to obtain a comparison result.

[0067] This method can perform initial screening on the subsequent waiting import instruction information when a large amount of import instruction information appears within a certain time interval, while comparing the count value with the corresponding local count value, so as to delete duplicate files. This can reduce the backlog of import instruction information and the processing time, thereby reducing the waiting time for subsequent import instruction information and improving processing efficiency.

[0068] Furthermore, if the number of repeated file data reaches a preset number within a preset interval, a response result including the number of repeated file data is issued. This method can avoid the increase in the number of repeated files caused by intermittent network, so as to prompt the relevant staff that a fault has occurred.

[0069] In some embodiments, when executing the import instruction information, the integrity of the file data in the import instruction information is checked. If the file data is incomplete data, the import instruction information is returned to the set cache middleware so that the cache middleware resends the import instruction information to the device. The message middleware records this step as a retry operation; this process can be understood as a network failure that may occur during the process of sending the import instruction information, resulting in incomplete file data in the import instruction information. The configured cache middleware does not require the card reader to resend the import instruction information. In another embodiment, if the number of retry operations reaches a preset number, the file data in the import instruction information is incomplete data, and the cache middleware sends a get message so that the card reader resends the import instruction information to the cache middleware. When the cache middleware re-receives the corresponding import instruction information, it sends the import instruction information at this time to the device.

[0070] In some embodiments, the method may further include: under normal circumstances, the import instruction information is used to instruct the smart card to execute the corresponding application, wherein the count field in the data field indicates the count value of the import instruction information, the CLA field indicates the category of the import instruction information, and the INS indicates the instruction code to be executed. In order to use the import instruction information to instruct the execution engine to enter the execution mode, the values ​​of the fields at the corresponding positions of the count field, the CLA field, and the INS field can be specially set, and set to special values ​​agreed with the smart card, that is, the first agreed value, the second agreed value, and the third agreed value.

[0071] For example, in a specific embodiment, the first agreed value, the second agreed value and the third agreed value may all be 01. In other examples, the first agreed value, the second agreed value and the third agreed value are, for example, 00, 01 and 02, respectively. In more embodiments, the first agreed value, the second agreed value and the third agreed value may also be other specific values, and there may be multiple first agreed values ​​and / or second agreed values ​​and / or third agreed values, for example, the first agreed value includes 00 and 01; the second agreed value includes 01 and 02, the third agreed value includes 01 and 02, and so on, and the setting of the agreed values ​​may be set according to the file data to be imported. It should be noted that the field position of the special value in the count field is different from the field position of the specific numerical value of the count value.

[0072] Accordingly, after receiving the import instruction information, the count field, the CLA field value and the INS field value are compared with the preset first agreed value, the second agreed value and the third agreed value respectively. If the field value of the count field is the first agreed value, the field value of the CLA field is the second agreed value, and the field value of the INS field is the third agreed value, it means that the import instruction information can be executed.

[0073] In one embodiment, there is a software tool on a PC. When a user clicks a service button, the server generates file data for a specific service and divides the file data into blocks to form APDU instructions. Since the data field of an APDU is at most 255 bytes, if the file data is greater than 255, it needs to be divided into multiple instructions. After the server organizes the APDU instructions, it will send them to the device (SE device). The application in the SE device receives the APDU instructions of the imported file data and caches them until all APDU instructions are received. At this time, the counter field in the data field corresponding to the APDU instructions is retrieved to compare whether the counter is greater than the local counter stored in the SE device application. The server generates file import data, sends APDU instructions, and the SE device application receives and processes them in sequence after the user clicks the service button.

[0074] The present application provides a method for importing file data, which includes adding an anti-replay count field to the APDU instruction data generated by the imported file data, and storing a local anti-replay count field for comparison and judgment when initializing in the SE device application. Only when the count value in the anti-replay count field corresponding to the APDU instruction is greater than the count value in the local anti-replay count field by 1, the file data import is allowed to execute, otherwise the instruction reports an error. The present application can ensure that the file data imported by the correct import instruction information can only be successfully imported once, avoiding the situation where the file data is repeatedly imported in abnormal scenarios.

[0075] Corresponding to the above method, the present application embodiment also provides a device for importing file data, such as Figure 3 As shown, the device comprises:
