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

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 cyber-physical 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.
