说明：  本文利用椭圆曲线上的双线性映射的特性, 提出了一种基于身份的双向认证及密钥协商协议, 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, 让通信双方能公平的协商会话密钥, 经过分析, 该协议能够抵抗重放攻击、中间人攻击和拒绝服务攻击, 具有较高的安全性, 此外, 协议还具有较高的效率。关键词: 双线性对; 双向认证; 密钥协商
(In this paper, an identity-based two-way authentication and key agreement protocol based on bilinear mapping on elliptic curve is proposed. This protocol realizes the mutual identity authentication function between the two sides of communication, enables the two sides of communication to confirm the identity of the other side, and also provides the function of key agreement, so that the two sides of communication can fairly negotiate session keys. After analysis, the protocol can resist heavy traffic. Play attack, man-in-the-middle attack and denial-of-service attack have high security. In addition, the protocol has high efficiency. Key words: bilinear pairing; bidirectional authentication; key agreement)
