Safety protection architecture for vehicle-mounted Ethernet

Abstract

The invention relates to the field of communication safety of an electric vehicle, and particularly relates to a four-layer network safety protection architecture for vehicle-mounted Ethernet, which comprises external interface safety, gateway safety, network safety and access safety. The external interface safety comprises a vehicle-mounted OBD diagnose interface and a remote service informationinterface; the gateway safety comprises safety-authentication gateway safety in a vehicle-mounted Ethernet structure, which takes charge of isolating external data from in-vehicle data; the access safety comprises software safety and data storage safety of a control system connected with the vehicle-mounted Ethernet; the network safety comprises safety of a vehicle-mounted Ethernet link and carries out packaging isolation on a line of the vehicle-mounted Ethernet; and the access safety comprises the software safety and the data storage safety of the control system connected with the vehicle-mounted Ethernet. The four-layer network safety protection architecture is simple in structure, high in implementation, stable, reliable and wide in adaptability.

Description

technical field [0001] The invention relates to the field of electric vehicle communication security, in particular to a four-layer network security protection framework for vehicle Ethernet. Background technique [0002] The emergence and popularization of electric vehicles and the Internet of Vehicles has greatly increased the demand for information circulation in today's society. Most of the structures in electric vehicles use electronic control structures to replace the original mechanical structures. Coordinated control between vehicles needs to be supported by a highly reliable and stable in-vehicle communication network. [0003] CAN bus is of epoch-making significance as a common vehicle internal communication network in the automotive industry. Its appearance makes more and more mechanical conduction structures that have always existed in the car no longer exist, and the vehicle control structure gradually turns to electronic control. Since the development of the I...

[0004] The reliability of network communication is always related to network security, but in the field of automobiles, since the emergence of in-vehicle communication networks, manufacturers have never considered the issue of network security. Individuals, this kind of communication strategy that does not consider network security is still feasible. Now that the development of networking has made more and more cars connected to the Internet, network security attacks have an increasing impact on cars.
