协议组合逻辑安全的4G无线网络接入认证方案

Secure access authentication scheme for 4G wireless network based on PCL

针对4G无线网络中移动终端的接入认证问题,基于自证实公钥系统设计了新的安全接入认证方案,并运用协议演绎系统演示了该方案形成的过程和步骤,用协议组合逻辑对该方案的安全属性进行了形式化证明。通过安全性证明和综合分析,表明该方案具有会话认证性和密钥机密性,能抵御伪基站攻击和重放攻击,并能提供不可否认服务和身份隐私性,同时提高了移动终端的接入效率。

Considering the access authentication for mobile terminals in the 4G wireless network,a new secure access authentication scheme based on the self-certified public key system was designed.Then the deductive process of the scheme was derived with the protocol derivation system and its security attributes was formally proofed with protocol composition logic.By the security proof and comprehensive analysis,it is showed that the proposed scheme not only has session authentication and key confidentiality,but also can defend pseudo-base station attack and reply attack,provide the undeniable service and identity privacy.Moreover,the scheme can improve the access efficiency of the mobile terminals.
