中文摘要：
针对移动用户漫游时需进行匿名认证问题，利用双线性对和椭圆曲线的相关特性，提出了一种基于身份的匿名无线认证协议．并对该协议的安全性和匿名性进行了详细分析，给出了移动用户匿名性在非认证链路模型下安全的形式化证明．分析表明，该协议实现了用户与接入点的双向身份认证和移动用户身份的匿名性，满足无线网络环境的安全需求．与同类协议相比计算量大幅减少，为匿名无线认证提供了一种较实用的解决方案．
英文摘要：
Considering the special requirements of the authentication protocol between the roaming users and the visited networks, an ID based wireless authentication protocol was proposed. The security of authentication and anonymity was analyzed in detail. Particularly, the anonymous security was analyzed by formal approach under the unauthenticated links adversarial model. It was showed that the proposed protocol could not only achieve authentication securely but also has a secure anonymity, and could satisfy the security requirements of the wireless network.
