摘要
针对车载自组织网(VANET)身份认证中的隐私信息保护问题,提出了一种新的基于线性方程组理论的匿名认证方案。该方案不使用传统的任何对称或非对称加密算法,而是利用线性方程组的求解理论,构建了一种匿名身份认证模型,在保证节点身份可认证的同时又防止了节点身份信息在非安全传输信道上泄露。此外,方案不仅满足了车辆单元节点(OBU)与路边单元节点(RSU)间的身份认证的需求,而且确保了车辆节点之间的身份认证。安全性和复杂性分析结果表明,所提方案安全可靠,且有较低的计算和通信开销。
Concerning to the problem of preserving users＇ identity privacy during the process of authentication in Vehicular Ad Hoc NETwork （ VANET）, a novel anonymous authentication scheme without cryptography based on the theory of linear equation was proposed. The scheme constructed an anonymous authentication model based on the basic theory of solving linear equations without employing any symmetric or asymmetric cryptosystem, which avoided disclosure of the identity information during the process of anonymous authentication. Besides, the proposed scheme not only satisfied the requirement of anonymous authentication between On Board Unit （OBU） and Road Side Unit （ RSU）, but also ensured the anonymous authentication among OBU. The results of the security and complexity analysis show that the proposed scheme is secure and efficient, and it needs low costs of computation and communication.
