近年来，基于混沌理论的密码学得到了迅速的发展，但大多数的研究都集中在密钥密码学上。基于混沌的公钥加密算法和密码协议还不多见，而混沌对网络安全也具有重要意义。提出了一种基于Chebyshev混沌映射的增强型密钥协商协议。利用Chebyshev多项式的半群性质，所提出的密钥交换算法类似于Diffie-Hellman算法。改进后的协议克服了几个以前提出的混沌密钥协商协议的缺点。分析和实验结果表明，该方法是有效的和安全的. (C)2010 Elsevier B. V.保留所有权利。
Cryptography based on chaos theory has developed fast in the past few years, but most of the researches focus on secret key cryptography. There are few public key encryption algorithms and cryptographic protocols based on chaos, which are also of great importance for network security. We introduce an enhanced key agreement protocol based on Chebyshev chaotic map. Utilizing the semi-group property of Chebyshev polynomials, the proposed key exchange algorithm works like Diffie-Hellman algorithm. The improved protocol overcomes the drawbacks of several previously proposed chaotic key agreement protocols. Both analytical and experimental results show that it is effective and secure.
