Safety guarantee method and system for ECU replacement of intelligent networked automobile

Abstract

The invention provides a safety guarantee method and system for ECU replacement of an intelligent networked automobile. The method comprises the steps of sending a communication request to a remote service provider TSP by special equipment SE, and establishing a secure communication channel; carrying out bidirectional identity authentication between the SE and the TSP; receiving identity identification information of an operator, and verifying the operator; receiving identity identification information of a vehicle owner, verifying the vehicle owner, and receiving first verification information of a vehicle associated with the TSP and the vehicle owner; connecting with the vehicle through an OBD interface based on the received vehicle information, acquiring second verification informationof the vehicle, and comparing the second verification information with the first verification information to verify the vehicle; receiving identity recognition information of a new ECU, sending the identity recognition information of the new ECU to the TSP for verification, and generating a new ECU digital certificate file and new ECU public key information by the TSP after the verification is successful; and flashing the digital certificate file to the new ECU, and sending the public key information of the new ECU to an AECU. By introducing the special equipment SE, the normal operation of the vehicle after the ECU is replaced is ensured.

Description

technical field [0001] The present invention relates to the field of information security of intelligent networked automobiles, in particular to a method and system for ensuring safety of replacing an ECU (Electronic Control Unit, electronic control unit) for intelligent networked automobiles. Background technique [0002] With the continuous improvement of the intelligence and networking of automobiles, the information security of intelligent networked vehicles has become increasingly serious. Hacking of intelligent networked vehicles has occurred from time to time, and car manufacturers have frequently recalled vehicles due to information security issues. Privacy protection, driving safety, traffic management, etc. have all caused serious threats, and the information security of connected vehicles has become the focus of attention of the automobile industry and even the whole society. figure 1 It is a schematic diagram of the internal network structure of the existing ICV,...
