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.
利用雙線性對理論,提齣一種三方密鑰交換協議,併對協議的正確性和安全性進行瞭分析.所提齣的協議中,用戶的公鑰由其身份信息經過哈希計算而得,私鑰生成中心PKG生成用戶的私鑰,三箇用戶間的會話密鑰由雙線性對計算齣.分析錶明,所提齣的協議是正確的,也是安全的.

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 the information of users’ identities ,the private keys generated by the private key generator PKG ,and the session key among three users’ com-puted by the content of bilinear pairing .The analysis shows that the proposed protocol is correct and secure .
