| 摘 要： | 利用双线性对理论，提出一种三方密钥交换协议，并对协议的正确性和安全性进行了分析。所提出的协议中，用户的公钥由其身份信息经过哈希计算而得，私钥生成中心PKG生成用户的私钥，三个用户间的会话密钥由双线性对计算出。分析表明，所提出的协议是正确的，也是安全的。

| Abstract: | Using the content of bilinear pairing, a two- party key exchange protocol was proposed, and the correctness and the security of the proposed protocol were analyzed. In the proposed protocol, the public keys of users＇ are computed through the hash functions with theinformation of users＇ identities, the private keys generated by the private key generator PKG, and the session key among three users＇ computed by the content of bilinear pairing. The analysis shows that the proposed protocol is correct and secure. |
