Vehicle-mounted quantum communication module safety system and method based on Trustzone

The invention relates to the technical field of vehicle-mounted quantum communication, in particular to a vehicle-mounted quantum communication module safety system and method based on Trustzone. The safety system is divided into a non-safety world and a safety world through the TrustZone technology, a safety protocol integration unit and a central processing unit are further arranged in the safety system, and the safety system is connected with a vehicle machine communication system through the safety protocol integration unit. Real-time data intercommunication is kept between the non-secure world and the secure world through the central processing unit; the non-secure world is used for managing a related interface of an external exposure service and is also used for carrying out key data intercommunication with the secure world. According to the invention, the Trustzone and the quantum communication technology are combined, and a security system which can perform real-time linkage monitoring and encryption
