| 摘 要： | 提出了一种新的身份认证与密钥协商协议，该协议可以实现通信双方的相互认证，并通过协商产生安全的会话密钥。协议将对称密码体制和非对称密码体制有机地结合起来，非对称密码体制采用密钥比特少且安全性高的椭圆曲线密码体制。经过性能分析，该协议安全、有效，比较适合在移动通信系统中使用。

| Abstract: | This paper proposed a new authentication and key agreement protocol which can realize mutual authentication and generate a secure session key agreed by both sides of communication. The protocol combines the symmetric with non-symmetric cryptography. Non-symmetric cryptography adopts Elliptic Curve Cryptosystem with greater security and shorter keys. Performance analysis shows this protocol is more secure and efficient. Therefore, it is suitable for mobile communication system. |
