摘要
基于身份的密钥交换协议通过协议参与者的身份信息来建立会话密钥。文章基于计算离散对数困难问题,提出一种基于身份的两方密钥交换协议,并对协议的效率和安全性进行了分析。分析表明,所提出的协议具有较好的运行效率,能满足两方密钥交换协议的安全属性要求。
ID-based protocols are used to establish session keys with identity information of principals.An ID-based key exchange protocol was proposed based on the difficulty of computing a discrete logarithm problem,and the performance and security of the proposed protocol were analyzed.The analysis shows that the proposed protocol has better performance and it can satisfy the security requirements of the two-party key exchange protocol.
