Improved remote authentication scheme with smart card
一种增强的基于智能卡的远程身份鉴别方案

This paper firstly analyzed some security problems in Lee-Chiu's remote authentication scheme with smart cards, and proposed an improved scheme. Compared with Lee-Chiu's scheme, this scheme can not only provide mutual authentication between clients and sever, but also avoid replay attack, guessing attack and forgery attack, so it can improve the security of the application systems.
