specific Embodiment approach

[0053] Specifically, the embodiment of the present invention also provides a specific implementation of a smart card operating system upgrade method, including the following steps:

[0054] A special upgrade interface is added during commercial program development. This interface is required to be the only way for all APDU commands, and can be set to open or close through configuration commands.

[0055] When the commercial program needs to be upgraded, open the upgrade interface. And implement the function of loading different upgrade programs according to different instructions in the interface, compile them into codes, and write them into EEPROM.

[0056] When the commercial program executes to this interface, it will automatically run in the EEPROM, load different upgrade programs according to the instructions, and return to the CODE area of ​​the commercial program to continue to perform subsequent functions after loading.

[0057] When the code executes to the CODE addr...

Abstract

The invention discloses an upgrading method for an intelligent card operation system. The upgrading method includes the steps that upgrading instructions for target programs are obtained, and target instructions are obtained; code-area entry addresses corresponding to the target instructions are saved into all upgrading code detection registers in intelligent cards through preset upgrading interfaces respectively; intelligent-card operation system codes are triggered to be interrupted through the upgrading code detection registers when running to the code-area entry addresses saved into any upgrading code register, and upgrading programs corresponding to the target instructions run in an EEPROM. According to the upgrading method, it is achieved that the code-area entry addresses corresponding to the different instructions can be repeatedly saved into the same upgrading code detection registers, the multiple code-area entries corresponding to the same instructions can be saved into thedifferent upgrading code detection registers, it is more efficiently detected that the entry addresses are upgraded through the operation system codes in the upgrading process of the intelligent cardoperation system, a limit of the number of the upgrading code detection registers is broken accordingly, and upgrading requirements of users are met.

Description

technical field [0001] The invention relates to the field of smart cards, in particular to a smart card operating system upgrade method and system. Background technique [0002] Smart card is the abbreviation of "smart card". It takes IC card technology as the core and uses computer and communication technology as the means to connect various facilities inside the intelligent building into an organic whole. The user can complete the usual key, fund settlement, attendance and some control operations through an IC card, such as using the IC card to open the door, IC card dining, shopping, entertainment, conferences, parking, patrolling, office, charging services and other activities. [0003] The operating system of the smart card will be continuously updated with the development of computer technology. The existing smart card operating system update method is to use the upgrade code detection register and EEPROM (Electrically Erasable Programmable Read and Write Memory, non-...
