摘要
电动汽车的无线充换电通信系统中,信道的开放性带来了安全问题。车辆用户真实身份的隐私保护和非法用户的可追踪性是两个互相矛盾的要求,安全认证技术的复杂度和时延要求也相互制约。围绕这两方面的需求,基于LTE-V2X车联网体系架构,设计一种具备强隐私保护能力的匿名认证机制。该机制同时满足V2X(Vehicle to Everything)通信的隐私性、匿名性、可鉴别、可追踪、完整性保护等多方面安全需求。基于NS-3网络仿真平台,对认证机制进行仿真实现,仿真结果满足安全需求,并证明了该机制具有实际部署能力和可扩展性,时延在毫秒量级,满足时延敏感的车联网环境下充换电通信业务的需求。
In the wireless charging communication system of electric vehicle, the openness of channel brings security problems. The privacy protection of vehicle users’ real identity and the traceability of illegal users are two conflicting requirements. The complexity and delay requirements of security authentication technology are also mutually restrictive. Based on the LTE-V2 X networking architecture, an anonymous authentication mechanism with strong privacy protection capability is proposed. This mechanism meets the security requirements of V2 X communication, such as privacy, anonymity, identifiability, traceability, integrity protection and so on. Based on NS-3 network simulation platform, the authentication mechanism was simulated and realized. The simulation results meet the security requirements, and prove that the mechanism has the actual deployment ability and scalability. The authentication delay is in milliseconds, which meets the demand of charging and switching communication service in the time-sensitive vehicle network environment.
