A Conditional Privacy-preserving Message Authentication Algorithm in VANET
-
摘要: 提出了一种VANET条件隐私保护消息认证(CPMA)的方法,采用分级认证技术,使用加密的Hash消息认证码(HMAC)进行证书吊销检查,减少了计算量,在保证安全性的前提下可以显著地减少消息认证延迟.仿真实验结果和分析表明了方法的有效性.Abstract: This paper proposed a Conditional Privacy-preserving Message Authentication (CPMA) algorithm.CPMA adopted hierarchical authentication technology and encryption Hash Message Authentication Code (HMAC) to check revocation certification.This algorithm reduce calculating complexity and the message authentication delay without compromising security.Simulation analysis and results show the effectiveness of CPMA algorithm.
