依据车载自组织网络的特点,提出了一种基于椭圆曲线零知识证明的匿名安全认证机制,利用双向匿名认证算法避免消息收发双方交换签名证书,防止节点身份隐私在非安全信道上泄露;利用基于消息认证码的消息聚合算法,通过路边单元协助对消息进行批量认证,提高消息认证速度,避免高交通密度情形下大量消息因得不到及时认证而丢失.分析与仿真实验表明,该机制能实现车辆节点的隐私保护和可追踪性,确保消息的完整性.与已有车载网络匿名安全认证算法相比,该机制具有较小的消息延迟和消息丢失率,且通信开销较低.

A secure anonymous authentication scheme was proposed based on elliptic curve and zero-knowledge proof, which adopts a bidirectional anonymous authentication algorithm to preserve users’ privacy during the certification process. In the case of a high density traffic scenario, a message aggregation technology was proposed to realize fast au-thentication by the assistant of RSU, and to avoid the loss of massive messages unauthenticated promptly. The simulation and analytical results show that the proposed scheme yields a much better performance than previously reported counter-parts with lower communication overhead, message loss rate and message delay.
