Authentication and key agreement protocol in mobile communication system
移动通信系统中的认证与密钥协商协议

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.
