Configurable financial smart card operation system architecture

Abstract

The invention discloses a configurable financial smart card operation system architecture, which comprises a transmission management module, a safety system module, an order processing module, a file management module, a user configuration module and a bottom driving module. The transmission management module is used for implementation of communication between a smart card and a peripheral terminal and guaranteeing accuracy of data transmission. The safety system module is used for implementation of data transmission and deciphering, card identification and verification and control of file access control permission. The order processing module is used for judging financial orders, calling the file management module and the safety system module for order processing according to parameters configured by users, and transmitting processing results and data to the transmission management module. The file management module is used for implementation of EEPROM (electrically erasable programmable read-only memory) file resource management and file setup, reading and writing. The user configuration module is used for implementation of individual configuration of user applications. The bottom driving module is used for controlling the bottom of a smart card chip.

Description

technical field [0001] The invention relates to a smart card operating system architecture, in particular to a configurable financial smart card operating system architecture with stronger practicability and wider application range in the financial field. Background technique [0002] Smart Card (Smart Card) is a general term for a plastic card embedded with an integrated circuit chip. According to the type of embedded chip, IC card can be divided into three categories: memory card, logic encryption card and CPU card, but only CPU The card is the real smart card. The integrated circuit in the smart card (CPU card) includes a central processing unit (CPU), a programmable read-only memory EEPROM, a random access memory RAM, and a card operating system COS (Chip Operating System) solidified in the read-only memory ROM. A microcontroller (MCU) with CPU, memory and peripherals acts as the overall control unit of the smart card. [0003] The operating system (Chip Operation Syst...

Problems solved by technology

Then, due to the rapid development of smart card technology, the formulation of international standards is relatively lagging behind. Although the financial field is generally based on the PBOC2.0 standard, there are still differences between applications due to different application scenarios and different system operators. One card for multiple purposes cannot be implemented between operating systems

[0007] 2. The cost of dedicated financial intelligence system is too high and the cycle is long

Due to the need to modify the smart card system, re-seal the card and the sales volume is small, the cost of the smart card system is high and the cycle is long
