身份基认证密钥协商协议

摘要

安全有效地传递信息是计算机安全通信研究领域的主要目标.为了使得用户间能在公开网络进行安全通信,文中提出了一种新的两轮双方认证密钥协商协议,通过分析新协议的安全属性指出了构造双方认证密钥协商的一些原则.该协议实现了通信双方的相互身份认证功能,使通信双方能确认对方的身份,同时还提供了密钥协商的功能.%Secure and efficient message delivery is one of the major aims of computer and communication security research. Aiming to solve the communication security problems which in a public network. An ID- based mutual authentication and key agreement scheme is proposed in this paper, in which some characteristics of bilinear map are used. The authors propose a new 2 rounds two party authenticated key agreement protocol and point out some principles to construct a secure protocol by analyzing the security properties of the protocol. The functions implemented by this protocolinclude authentication, guaranteed the ingegrity and agree the session key fairly between two communications.
