为解决下一代高速铁路下5G-R无线通信系统切换认证协议中切换密钥不具有前向安全性和认证效率低的问题，提出了一种新的5G-R切换认证和密钥协商算法。第一，用认证信息代替切换请求消息中的身份信息，克服了身份信息明文传输的缺点。其次，设计了一种基于格理论的切换密钥更新策略。利用格上的特征函数和辅助模函数实现了切换密钥的动态更新和前向、后向安全性。第三，增加消息认证码，实现通信双方的相互认证，可以有效防止重放、中间人等恶意攻击。最后，串空间形式化方法用于安全性验证。结果表明，该方法不仅具有较高的安全性和效率，而且能够满足下一代5G-R切换认证的高安全性要求。
In order to solve the problems that the handover key in the handover authentication protocol of 5 G-R wireless communication system under the next-generation high-speed railway does not have forward security and authentication efficiency is low, a novel 5 G-R handover authentication and key agreement algorithm is proposed. First, the authentication information is used to replace the identity information in the handover request message, which overcomes the shortcomings of the clear text transmission of the identity information. Second, a handover key update strategy based on lattice theory is designed. The dynamic update and forward and backward security of the handover key are realized by using the feature function and the auxiliary module function on the lattice. Third, the message authentication code is added to realize mutual authentication between communication parties, which can effectively prevent replay, the man in the middle, and other malicious attacks. Finally, the strand space formalization method is used for security verification. The results show that the proposed method not only has higher security and efficiency than other comparison methods but also can meet the high-security requirements of the next-generation 5 G-R handover authentication.
