Problems solved by technology

At present, most communication security mechanisms are only XOR check or CRC check. Although fake or wrong messages can be detected, since all data is transmitted in plain text, the check algorithm is easily reversed, which leads to the safety of automobile use. question

Abstract

The invention discloses an encryption communication method and device for algorithm verification and a vehicle. The encryption communication method comprises the steps that a first data packet is generated; algorithm verification is carried out according to the first data packet and a security identification code to generate a second data packet, a message is generated from the first data packet and the second data packet to be transmitted, wherein the security identification code is preset; and algorithm verification is conducted according to the received first data packet and the security identification code to generate a third data packet, and the third data packet is compared with the received second data packet to judge whether the message is discarded or not.

Description

Technical field [0001] The present invention relates to the field of secure vehicle communication, and particularly relates to an encryption communication method, encryption communication device and the vehicle. Background technique [0002] With the rapid development of intelligent network linking and automatic driving, the message generated by the car more and more interactive, using the communication security-related messages more and more. Most communications security mechanisms just XOR checksum or CRC check, although you can detect camouflage or error message, but because all the data is transmitted in clear text, checksum algorithm is very easy to reverse out, resulting in the use of car safety problem. Inventive content [0003] Embodiment of the present invention provides a method of encrypted communication, the encryption communications device and the vehicle. [0004] Embodiments of the invention provides a method of encrypted communication for verification algorithm,...
