面向车联网通勤的双阶段认证密钥协商协议
Two-stage authentication and key agreement protocol for commuting in Internet of vehicles
摘要
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.关键词
