A vehicle network safety protection method based on Internet of Vehicles and a vehicle network architecture

Abstract

The invention provides a vehicle network safety protection method based on Internet of Vehicles and a vehicle network architecture. The method comprises the following steps: establishing a plurality of security defense layers for a whole vehicle network, wherein the plurality of security defense layers at least comprise an Internet of Vehicles defense layer, a whole vehicle electronic and electrical architecture defense layer, a vehicle-mounted network defense layer and an automobile electronic controller physical defense layer; For each security defense layer, selecting a preset security defense technology corresponding to the security defense layer to realize network security protection of the whole vehicle, wherein a firewall technology is correspondingly adopted by the Internet of Vehicles defense layer, and a central gateway technology is correspondingly adopted by the whole vehicle electronic and electrical architecture defense layer; Wherein the vehicle-mounted network defense layer correspondingly adopts a network message MAC encryption technology, and the automobile electronic controller physical defense layer correspondingly adopts an EVITA-based security hardware moduletechnology. The network attack can be effectively resisted, and the network security of the whole vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle network-based safety protection method and vehicle network architecture. Background technique [0002] At present, the remarkable features of pure electric intelligent networked vehicles are reflected in the high degree of electronic control of the vehicle system, the number of ECUs (Electronic Control Units, electronic controllers) has increased significantly and the number of interactive functions has increased significantly, and the amount of software codes and control algorithms has increased significantly. At the same time, the system The risk of sexual vulnerabilities has also increased, which has also led to an increase in cyber attacks on vehicles by "hacker" organizations or individuals with commercial or other purposes, such as modification of vehicle safety limit parameters, tampering of vehicle odometers, OBD (On- Board Diagnostic, on-board diagnostic sy...
