基于混沌映射的无线网络环境三因子身份认证协议

THREE FACTOR AUTHENTICATION PROTOCOL IN WIRELESS NETWORK ENVIROMENT BASED ON CHAOTIC MAPS

针对无线网络环境当中的身份认证协议易受伪造攻击、重放攻击、用户模仿攻击、计算开销大、不能够提供匿名性等问题,提出一种基于三因子(口令、智能卡、生物特征)的身份认证密钥协商协议。通过BAN逻辑证明了通信实体之间的相互认证,利用AVISPA工具对该方案进行了仿真。安全性分析表明,该认证协议能够实现匿名性、相互认证、会话密钥协商并且能够抵御常见攻击。效率分析表明,该协议通信开销最少,效率更高。

Aimed at the problems that the identity authentication protocol in the wireless network is vulnerable to forgery attack,replay attack,user imitation attack,with high computational overhead,and can not provide anonymity,an identity authentication key agreement protocol based on three factors(password,smart card and biometric)is proposed.The mutual authentication between communication entities was proved by BAN logic,and the scheme was simulated by AVISPA tool.Security analysis shows that the authentication protocol can realize anonymity,mutual authentication,session key negotiation and resist common attacks.Performance analysis shows that the authentication protocol has the lowest communication overhead and higher efficiency.
