Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.
In the embodiment of the present invention, it should be noted that the post-COS download of the smart card refers to a download update after the smart card is issued.
Referring to fig. 1, the main method steps of the embodiment of the invention are: s100, powering on reset of the intelligent card COS, checking state configuration, and entering a post-download mode; s200, remotely downloading a corresponding update data packet to update, wherein the data source of the update data packet is an engineering hex file; s300, after updating is completed, switching to a normal working mode.
In some embodiments of the invention, referring to fig. 2, the state configuration includes: a status flag bit indicating that there is updated content and status flag content indicating whether the present smart card has completed updating. After the COS of the smart card is powered on and reset, the status flag bit is checked first to judge whether the update content exists. In this embodiment, the status flag is not null, indicating that there is updated content. If the update content exists, the status flag content is further checked to determine whether the smart card has completed updating, and in this embodiment, the status flag content is not the initial default value, which indicates that the update has been completed. And when the update content exists and the smart card does not complete the update, the COS of the smart card enters a post-download mode, otherwise, the COS of the smart card enters a normal working mode, and a normal working flow is started. It will be appreciated that the enabling of the update download after the smart card COS may also be done in other ways, such as a non-repeating sequence of numbers, only if the number of the present smart card is not equal to the remotely acquired number, indicating that there is an update.
In some embodiments of the present invention, referring to fig. 3, S200 includes: s210, remotely downloading a corresponding update data packet, and performing data inspection on the update data packet to judge whether the update data packet is normally downloaded; s220, deleting the updated data packet if the downloading is wrong, and entering a normal working mode in a downloading mode after exiting; s230, if the downloaded data packet is normal, the corresponding content is more relevant. In the embodiment of the invention, whether the downloaded data is correct is judged by CRC check, and it is understood that whether the downloaded data is correct can also be judged by other check modes. In the updating process, if abnormality occurs, the system returns to the post-download state mode, so that the updated functions can be ensured to be normally used. And when the updating is normal, the corresponding state mark content is modified, the updating is completed, and the normal working mode is switched to prevent repeated updating.
In some embodiments of the present invention, the update package construction process is described with reference to fig. 4 and 5. Firstly, the intelligent card COS acquires an engineering hex file, and interprets the content of the file. If the interpretation is wrong, stopping the construction; and if the interpretation is normal, performing data normalization on the interpretation content. And (5) completing the construction after successful standardization, and stopping the construction after failure. It will be appreciated that for a build that stops after failure, the problem is left to be verified and modified and then the build is performed again until the build is successful. The detailed process of data standardization is shown in fig. 5, firstly, counting the number of lines of the interpretation content, packaging each line of data by taking a fixed size of 10K as a block, and filling 0 into the last block of data to keep the size of the last block of data as a multiple of a preset value of 8. In this embodiment, after all the data are processed, the calculation of the CRC check value is also included. When other verification methods are adopted for the correct detection of the downloaded update package data, it can be understood that the construction of the update package also includes calculation of corresponding contents.
In some embodiments of the invention, the system includes 3 modules: the data packet construction module 100, the status checking module 200 and the post download updating module 300. The data packet construction module 100 is configured to construct an update data packet according to the engineering hex file; a status checking module 200, configured to check the status configuration, and determine whether a post download mode needs to be entered; the post-download updating module 300 is used for downloading and updating the update data packet.
In an embodiment of the present invention, the post-download update module 300 includes a download module 310 and an update module 320. A download module 310, configured to download a corresponding update data packet, and check whether the downloaded data is normal; the updating module 320 is configured to update the content of the update data packet and check whether the update is normal.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present invention.
