两轮的口令认证的两方密钥交换协议

摘要

For the requirement of key exchange protocol for password authentication,we propose a two-party key exchange protocol for password authentication by using relevant contents of ID-based encryption algorithm,bilinear pairing and hash function,and analyse the protocol from two aspects of security and efficiency.It is showed in the analysis that the protocol has high efficiency,it has also the security property of two-party key exchange protocol as well.%对于口令认证密钥交换协议的要求,利用基于身份加密算法、双线性对与哈希函数的相关内容,提出一种口令认证的两方密钥交换协议,并对该协议进行安全性和效率的两个方面的分析.分析表明,该协议具有较高的效率,并具有两方密钥交换协议的安全属性.
