【摘要】：为了解决当前车载网隐私保护机制的安全性和效率问题,基于安全多方计算理论和匿名认证协议,提出了一种新的车载网节点隐私保护方案.该方案利用线性方程组的求解理论,采用安全高效的茫然传输机制,避开了传统的计算复杂的公钥密码算法.对方案的安全性和效率分析的结果表明,新方案不仅能够解决车载网中发送者隐私、接收者隐私、匿名性、共谋攻击、重放攻击等多种安全问题,而且认证效率也得到了有效提高,在计算性能受限的物联网环境中,具有理论和应用价值.
[Abstract]:In order to solve the security and efficiency problems of the current privacy protection mechanism of vehicular network, based on the theory of secure multi-party computing and anonymous authentication protocol, In this paper, a new privacy protection scheme for vehicular network nodes is proposed, which utilizes the solution theory of linear equations and adopts a secure and efficient blankly transmission mechanism. The results of security and efficiency analysis show that the new scheme can not only solve the privacy of sender, receiver, anonymity, collusion attack, but also can solve the problem. Replay attacks and other security problems, and the efficiency of authentication has been effectively improved, in the computing performance of the Internet of things environment, has theoretical and application value.
