摘要
为减少车辆自组网中隐私保护过程的通信延迟,提高认证效率,论文在形式化描述车辆之间的通信(V2V)的基础上,设计了一个V2V通信协议,利用Applied Pi演算证明了它的前向安全性和不可跟踪性,并联合Vanet Mobi Sim和NS2平台仿真验证了V2V通信过程的性能,比较了在不同速度下,V2V通信与V2I通信的认证时间与认证效率。
In order to reduce communication latency and improve efficiency certification in privacy protection process of VANET,this paper describe a formal analysis of V2V(Vehicle to Vehicle)communicationwith applied pi calculus,design a simple protocol for the process and prove it meet forward privacy and intractability.And V2 V communicationperformances aresimulated on the platform combining Vanet Mobi Simand NS2.The authentication time and efficiency are comparedbetween V2 V and V2 I communicationat different speeds.
