The proposed framework aims to resolve the issues of mobile vehicle security, includingthe 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 societylayers, this paper constructs an integrated intelligent safety response strategy for physical equipment informationsecurity, 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 eventprediction before the event, immediate alarm during the event, and replay for evidence forensics after the event.
