一种新的基于智能卡的双向身份认证方案设计

A New Mutual User Authentication Scheme Using Smart Card

身份认证问题是网络安全中的重要研究课题。最近,Chien等人提出了一种有效的基于智能卡的身份认证方案,但从文献[8]及本文的分析看,该方案容易遭受Reflection Attack,ParallelAttack、重传攻击等。在分析其方案漏洞的基础上,提出了一种新的双向身份认证方案。

User authentication is the important problem in network security. Recently, Chien et al proposed an efficient user authentication scheme using smart card, however,it can see that their scheme is vulnerable to a Reflection Attack,Parallel Attack, Replay Attack and so on. Herein, this paper first shows the weakness of Chien et al＇s scheme, and then proposes a new improved scheme with better security.
