Abstract: According to anonymous request of mobile internet security.An identity-based cryptography mutual authentication protocol is proposed to resolve the problem of identity authentication and key agreement in mobile communication，It can provide anonymous service that guarantees the confidentiality of the mobile users’ identity.The research results reveal that the protocol has a good anonymous property，and is efficient and feasible and achieves the ideal security requirements of anonymity for Wireless Mobile Internet.

Key words: anonymit, identity authentication, key agreemet

摘要： 针对移动互联网络安全性的匿名需求，论文在基于身份的公钥系统的基础上，设计了一个双向匿名认证协议，该协议提出移动互联网络通信中的匿名身份认证和密钥协商方案，实现了通信双方的相互认证，并使移动网络向移动用户提供匿名服务，保护用户身份信息，分析表明协议具有很强的匿名性，而且高效可行，满足移动互联网络匿名性的安全需求。
