Method for IC card and security information interaction terminal authentication, IC card and security information interaction terminal

Abstract

The invention provides a method for IC card and security information interaction terminal off-line authentication and an IC card and a security information interaction terminal which are capable of using the method. According to the method, after a data communication link is established between the IC card and the security information interaction terminal, the security information interaction terminal sends an authentication instruction to the IC card to execute the authentication of the security information interaction terminal, wherein the authentication is conducted off-line. According to the method for IC card and the security information interaction terminal off-line authentication and the IC card and the security information interaction terminal which are capable of using the method, safety performance is enhanced.

Description

technical field [0001] The present invention relates to an authentication method, an IC card and an information interaction terminal, more specifically, an off-line authentication method for an IC card and a security information interaction terminal, and an IC card and a security information interaction terminal. Background technique [0002] At present, with the increasingly widespread application of IC cards and the increasing variety of services in different fields, through the security information between IC cards (such as traffic cards) and security information interaction terminals (such as POS machines) (that is, security It is becoming more and more common to implement different applications (such as traffic card top-up) by requiring high-level information (such as password) interaction (especially security information interaction in offline situations). [0003] However, in the existing security information interaction system, the IC card and the security informatio...

AI Technical Summary

Problems solved by technology

The PSAM card is exposed on the terminal and is extremely vulnerable to attacks. At the same time, the key management (such as transmission, distribution, update, recycling, etc.) is complicated, which limits the cross-regional use of the card), resulting in the following potential security risks: counterfeit Unauthorized terminals (such as POS machines) can interact with IC cards (such as traffic cards) for offline security information (such as performing offline recharge operations for traffic cards)
