在2009年,Tseng等人提出了一种基于密码共享和混沌映射的密钥协商协议(Tseng et al. s协议)。他们声称该协议提供了服务器和用户之间的相互认证,并允许用户匿名与服务器交互以建立共享会话密钥。然而,在2011年,Niu等人已经证明Tseng等人'当存在合法用户的内部攻击者时,协议不能保证用户的匿名性和协议的安全性。它也不能提供完美的前向保密性。然后,Niu等人在他们的协议设计中引入了信任第三方(TTP)(Niu等人,s协议)。但根据我们的研究,Niu et al.的协议被发现有几个不令人满意的缺点。基于对Tseng et al.的协议,并给出了一些改进,以满足原来的安全性和性能要求。同时,我们提出的协议克服了Tseng等人的安全缺陷。的协议。
In 2009, Tseng et al. proposed a password sharing and chaotic map based key agreement protocol (Tseng et al.’s protocol). They claimed that the protocol provided mutual authentication between a server and a user, and allowed the user to anonymously interact with the server to establish a shared session key. However, in 2011, Niu et al. have proved that Tseng et al.’s protocol cannot guarantee user anonymity and protocol security when there is an internal adversary who is a legitimate user. Also it cannot provide perfect forward secrecy. Then Niu et al. introduced a trust third party (TTP) into their protocol designing (Niu et al.’s protocol). But according to our research, Niu et al.’s protocol is found to have several unsatisfactory drawbacks. Based on reconsidering Tseng et al.’s protocol without introducing TTP, we give some improvements to meet the original security and performance requirements. Meanwhile our proposed protocol overcomes the security flaws of Tseng et al.’s protocol.
