5G时代车联网信息物理融合系统综合安全研究

Integrated security of cyber-physical vehicle networked systems in the age of 5G

近年来,重庆公交坠江、无锡重型卡车超载致高架坍塌等一系列重特大灾难性事故的发生暴露了信息化时代交通工具运行中安全防范与应急处置机制的严重缺失. 5G通信时代的来临,无疑为这一问题的解决带来了巨大历史机遇.本文针对交通工具运行中预防重特大事故及取证分析的需求,基于5G通信技术,提出基于事件的交通工具运行中信息物理融合安全治理框架.该框架围绕交通工具运行安全问题的特性——"高速运动状态下网络资源的可用性、信息物理融合下安全目标的复杂性",通过精准感知物理层、通信层、社会层3个层面的不安全事件,综合利用泛在智能感知、边缘–云计算等技术,从交通工具的物理设备信息安全、车辆状态安全、车辆环境安全、网络安全4个维度,构建一体化的交通工具智能安全应对方案,服务于"事前全时预判、事中即时报警、事后回放取证"的安全目标.

In recent years, a series of serious catastrophic traffic accidents, such as the Chongqing bus crash and Wuxi Road bridge collapse, revealed some serious issues in the mobile vehicle safety and emergency response mechanisms. The advent of 5G communication has undoubtedly created some great opportunities for solving these issues. In order to fulfill the requirements of serious traffic accident prevention and forensic analysis,this paper proposes an event-based mobile vehicle cyber-physical security governance framework based on 5G communication technology. The proposed framework aims to resolve the issues of mobile vehicle security, including the availability of network resources in high-speed motion and the complexity of security objectives within cyberphysical systems. Relying on precise perception of insecure events at the physical, communication, and society layers, this paper constructs an integrated intelligent safety response strategy for physical equipment information security, state vehicle security, environmental vehicle security, and network security by intelligent perception,edge-cloud computing, and other technologies. The proposed framework achieves the goals of real-time event prediction before the event, immediate alarm during the event, and replay for evidence forensics after the event.
