Encryption processing method and system for automobile remote control message

Abstract

The invention discloses an encryption processing method and system for automobile remote control messages. The method includes: a central gateway broadcasts its own VIN code to the first CAN bus and the second CAN bus; The first encryption algorithm calculates the first-level dynamic rolling code, and then inputs the first-level dynamic rolling code to the second encryption algorithm to calculate the second-level dynamic rolling code and stores it, and at the same time, the first-level dynamic rolling code is sent to the central through the second CAN bus Gateway; the central gateway forwards the first-level dynamic rolling code to the remote control module through the first CAN bus; the remote control module inputs the first-level dynamic rolling code to the second encryption algorithm to calculate and execute the rolling code; the remote control module executor judges and executes the rolling code The code matches the second-level dynamic rolling code, and decides whether to respond to the control command sent by the user terminal according to the match. The invention can reduce the risk of communication messages being attacked and improve security.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an encryption processing method and system for automobile remote control messages. Background technique [0002] With the advent of intelligent automobiles, users' demand for intelligent products is constantly increasing. Remote control has become an intelligent product service and is favored by more and more users. Therefore, major OEMs use remote control services as a whole The main intelligent configuration improvement item created by the car invention. [0003] At present, there are many cars with remote control service on the market, but the remote control service increases the risk of the vehicle being attacked, especially the communication messages between the remote control module and other modules of the vehicle are at high risk of being attacked, which is prone to CAN data playback The attack situation affects security. [0004] Therefore, when the whole vehicle i...
