Research On Identification Protocol In Smart Card

Identity authentication protocol is a part of cryptography protocol and play a important role in protecting information from unauthorized access. Identity authentication is the first defence for system ,thus it is necessary to strength the research for identity authentication.Recently,more and more applications are based on smart card,so this paper mainly pay attention to identification protocol in smart card.In the former part of this paper.we analyse some identity identification schemes used for smart: card field and introduce some identification protocols suitable for smart card. Then a efficient protocol is proposed which based on a known identification protocol and proved by constructive reduction methods.Subsequently,a ID-based interactive identity authentication scheme with shared verification scheme is proposed.This scheme combine a identification protocol with a secret sharing scheme with access structure and improve known authentiation scheme with shared verfication and resolve the situation in which n verifiers have different right. Every verifier holds only one subsecret and everyone's subsecret can be used repeatedly.
