一类快速易行的智能卡认证协议

A Fast and Practical Mutal Authentication Protocol for Smart Card

基于单向 Ｈ Ａ Ｓ Ｈ 函数的快速和单向性，构造了一个适合于智能卡实现的认证协议，该协议完全性好，且较之于其定的智能卡认证协议要更快速更快速和便于实现。

Based on the speediness and unidirectional of one\|way hash function,we construct an authentication protocol suitable for smart card which gains high security.This protocol is quicker and easier to actualize than other protocols used in smart card and can achieve duplex authentication.
