中文摘要：

在Waters的基于身份加密方案的基础上提出了一种高效的基于身份认证密钥协商协议，并在标准模型下证明了该协议的安全性．与目前已有的同类协议相比，该协议具有更高的效率和更弱的安全假设，并具有已知密钥安全和前向安全性等安全性质，同时能够抵抗未知密钥共享和密钥泄露伪装攻击.在该协议基础上，构造了防止用户密钥生成中心获取会话密钥的协议，以满足需要防止密钥托管的应用需求，并采用安全的消息认证码算法为该协议增加了密钥确认过程．

英文摘要：

This paper proposes an efficient Identity-Based authenticated key agreement protocol based on Waters＇ Identity-Based Encryption scheme and gives a detail security analysis with provable security techniques in the standard model, It is more efficient than other similar protocols, and provides known-key security and forward secrecy. And it also resists key-compromise impersonation and unknown key share attacks. Moreover, this protocol is extended to satisfy the requirement that the session key should be escrowed by the Private Key Generation （PKG） center, and is given a key confirmation property with a secure message authentication code algorithm.
