Encryption method for whole vehicle control protocol of to-be-open-source vehicle platform

The invention relates to an encryption method for a whole vehicle control protocol of a to-be-open-source vehicle platform, and aims to solve the problem of low safety performance after a whole vehicle platform protocol is opened in the prior art. The method comprises the following steps: adding a private CAN channel for carrying out message interaction with a development control end on a gatewayof a to-be-opened source vehicle platform; routing protocols are established on a gateway and an actuating mechanism of a to-be-opened source vehicle platform respectively; wherein a data segment of amessage interacted between the development control end and the gateway and a data segment of a message interacted between the gateway and the execution mechanism both comprise data parameter bytes used for being filled with data and check code bytes used for being filled with check codes; and respectively solidifying a check code algorithm on the gateway and the execution mechanism, so that checkcode bytes when the same m
