2007年，Xiao等人提出了一种新的基于混沌映射的密钥协议。然而，最近，Han等人指出，Xiao等人的协议对于他们开发的新攻击是不安全的，这些攻击可能会阻碍用户和服务器完成共享的秘密会话密钥。除了Han等人的攻击外，本文还证明了Xiao等人的协议容易受到离线密码猜测攻击。在此基础上，本文提出了一种新的基于混沌映射的密钥协商协议，以隔离此类安全问题。与Xiao等人的协议相比，所提出的协议更安全，并且可以减少通信轮数。
In 2007, Xiao et al.’s proposed a novel key agreement protocol based on chaotic maps. Recently, Han et al., however, pointed out that Xiao et al.’s protocol is not secure against their developed new attacks which can hinder the user and the server from accomplishing a shared secret session key. In addition Han et al.’s attack, the current paper demonstrates that Xiao et al.’s protocol is vulnerable to off-line password guessing attack. Furthermore, the current paper presents a new key agreement protocol based on chaotic maps in order to isolate such security problems. In contrast with Xiao et al.’s protocol, the proposed protocol is more secure and can be reduced the numbers of communication rounds.
