Abstract

The invention provides a V2X communication method and device and a vehicle. TEE and REE are simultaneously operated in an AP processor of the V2X communication device, V2X application programs used for carrying out V2X communication in the AP processor all run in the TEE; therefore, the V2X application program is isolated from other application programs, the V2X application program can independently process the V2X data in the TEE; through the TEE, the V2X application program is ensured not to be influenced or attacked by other application programs when the V2X application program processes the V2X data; therefore, the safety of the V2X application program running in the TEE in receiving and sending V2X data is ensured. According to the V2X communication device provided by the invention, the TEE running on one AP processor can improve the safety performance of the V2X application program during V2X communication, and an independent processor does not need to be arranged, so that the structure of the V2X communication device is simplified, and the hardware cost can also be reduced.

Description

Technical field [0001] This application relates to the field of vehicle network technology, and in particular to a vehicle to everything (V2X) communication method, device and vehicle. Background technique [0002] With the development of network technology and intelligent vehicle technology, the Internet of Vehicles has received more and more attention. At present, in the vehicle networking communication system, the vehicle to everything (V2X) communication device (or called the vehicle networking terminal) is installed inside the vehicle, and V (car) and X (car, car, People, traffic roadside infrastructure and network) intelligent information interaction. [0003] Since the V2X communication data is closely related to the safety of the vehicle, it is also necessary to ensure the safety of the data when the V2X communication device performs V2X communication. In one technology, the V2X communication device that sends the data can use the key to encrypt the V2X data and then send...
