Abstract

The invention aims to disclose a smart card security session system. The system comprises a smart card, wherein the smart card consists of a security session manager, a transmission manager, a command analyzer and an encryption and decryption module; the security session manager, the transmission manager and the command analyzer are connected one another; the encryption and decryption module is connected with the command analyzer; in the conventional smart card security system, the concept of security session is introduced, and the application program is associated with a request initiated per se by adopting a semi-permanent interactive information switching method with automatic recovery mechanism, which is established between the smart card and a terminal application program in a certain period, so as to ensure that the security sessions of different application programs are independent from one another; and in addition, once established, the security session exists all the time until the operation of the application program is finished or other conditions for stopping the security session occur; and the security of the session is protected by security session symmetric keys and a security session public and private key pair.
