摘要
针对通勤车辆在车联网中向路边单元(RSU)获取服务的安全与效率问题,提出了一种双阶段的认证密钥协商协议.在初始认证阶段,利用车辆、RSU和可信机构(TA)间协商的3个独立会话密钥,保障2个实体间传输的隐私不被第三方实体窃取.在快速认证阶段,车辆和RSU间利用车辆旅行时间表高效地完成相互认证.协议支持车辆匿名与匿名追溯,且能防止通勤路线等隐私泄露.此外,通过随机预言机证明了协议的安全性.仿真结果表明,在典型通勤场景下,所提方案比同类方案降低了59.35%的计算开销和44.21%的通信开销.
Abstract
Aiming at the security and efficiency of commuter vehicles accessing services from road side unit(RSU)in In-ternet of vehicles(IoV),a two-stage authentication and key agreement protocol was proposed.In the initial authentica-tion phase,the three independent session keys,negotiated among the vehicle,the RSU,and the trusted authority(TA),were utilized to safeguard the privacy of transmitted data between two entities from interception by third-party entities.In the fast authentication phase,the vehicle and RSU utilized the vehicle's travel schedule to reach the high-efficiency mutual-authentication.The vehicle anonymity and anonymous traceability were supported by the protocol,and the pri-vacy leakage such as commuting routes was prevented.Additionally,the security of the protocol was proven by a random oracle.In a typical commuting scenario,the simulation results show that the protocol outcomes a reduction in computa-tion overhead by 59.35% and communication overhead by 44.21%,compared to existing similar literature.
