Development of smart card operating system

Abstract

The project divide in two parts, the first part is to develop a smart card operating system and the second part is to write an application interface. First, write a smart card operating system to control the read, write of the EEPROM area of the smart card. In my operating system, there are totally 2 modes, issuer mode and user mode. These two modes define two different ways of protecting the card. The issuer mode can have higher privilege than the user mode. It is used to initialize and personalized of the card. After the card release to user, it will change to user mode, this mode cannot change to issuer mode because a logical fuse is ¡§blown¡¨ and it is irreversible. The user mode has more limits to access the read write of EEPROM area of smart card. Second, the application interface is used to communicate with the smart card through a suitable card reader. It is used to write the data to, to get the data from the smart card. The interface sends the suitable command (APDU commands) to the smart card, and then the operating system gives back reply and the interface receives it.
