摘要
V2X(vehicle to everything)车联网是借助新一代信息通信技术将车辆与其他车辆、路侧基础设施以及其他道路使用者相连接进行信息交互的新型网络,有助于提高交通运输效率,减少环境污染,节约能源资源,降低事故发生率,改进交通管理.V2X车联网安全是其健康运行和发展的关键.分析了V2X车联网需要关注的重点安全需求,结合电子认证技术、V2X车联网公钥基础设施和各种V2X证书的应用,从车辆到车辆(V2V)、车辆到路侧设施(V2I)、路侧设施到车辆(I2V)3个应用场景论述了电子认证在车联网中的安全实现和应用效果.
Vehicle-to-everything(V2X)gets help from the new generation of information and communication technology,which lets vehicles exchange information with vehicles,roadside units,and other road users,thereby improving traffic efficiency,saving resources,reducing pollution and accident rates,and improving traffic management.The security of V2Xis the key to its normal operation and development.The article analyzes the key security requirements of V2X,as well as the combination of electronic authentication technology,V2Xpublic key infrastructure,and various V2Xcertificate applications.The three application scenarios,Vehicle-to-Vehicle(V2V),Vehicle-to-Infrastructure(V2I),and Infrastructure-to-Vehicle(I2V),are used to discourse the secure implementation and application effects of electronic authentication in V2X.
