摘　　要：针对移动用户漫游时的认证问题,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方案,并对该方案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,该方案在保证用户身份不被泄漏的前提下,实现了用户与接入点之间的双向身份,满足无线网络环境的安全需求。此外,与同类方案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。Considered the especial requirements of the authentication scheme among the roaming users and the visited networks, an ID-based wireless authentication scheme with anonymity was proposed by the bilinearity and non-degeneration of pairings. The security of authentication and anonymity was analyzed in detail. Especially, the anonymous security was analyzed by formal approach under the unauthenticated-links adversarial model. It is showed that the proposed scheme not only could achieve authentication securely but also has a secure anonymity , and could achieve the secure requirements of the wireless network. Moreover, the scheme is simple and efficient, and could be applied to the authentication in the wireless network.
