Title:
V2X COMMUNICATION METHOD AND DEVICE, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2021/135999
Kind Code:
A1
Abstract:
The present application provides a V2X communication method and device, and a vehicle. TEE and REE are simultaneously run in an AP processor of a V2X communication device; all V2X applications used for V2X communication in the AP processor run in the TEE so as to isolate the V2X applications from other applications, such that the V2X applications are able to independently process V2X data in the TEE. The use of TEE prevents the V2X applications from being affected or attacked by other applications when processing V2X data, thus ensuring the security of the V2X applications running in the TEE when transmitting and receiving the V2X data. The TEE that can run in an AP processor of the V2X communication device provided by the present application improves the security performance of V2X applications during V2X communication, and there is no need to provide an individual processor, so that the structure of the V2X communication device is simplified, and hardware costs can also be reduced.
