摘要
针对传统认证存在身份信息破解风险、物理层认证无法实现初始认证的问题,提出一种结合身份信息和物理层位置信息的跨层双向认证方案。利用物理层提供的熵增加认证系统的共享随机性,在防止身份信息破解条件下实现认证。首先提出一种跨层认证信息生成方案,随后分析认证性能。仿真结果表明,该方案有望实现信息论安全双向认证,且增加认证信息长度或者提高信噪比可以显著提升认证性能。
In order to solve the problem of identity information cracking in traditional authentication and the initial authentication failure of the physical layer authentication, this paper proposes a cross-layer mutual authentication scheme, combining the identity information and the physical layer loca-tion information. Specifically, we use the entropy supplied by the physical layer to increase the common randomness of the authentication system to achieve authentication while preventing the identity information cracking. We first introduce a generalized cross-layer authentication message generation scheme. Then, the authentication performance of the proposed scheme is analyzed. Simulation resuits show that this scheme is expected to achieve information theoretic security mutual authentication. Furthermore, authentication performance increases significantly with the growth of authentication message length and the signal to noise ratios （SNR）.
