Abstract

The invention discloses a vehicle-mounted Ethernet firewall system and a communication delay determination method and device, and the system comprises at least one terminal firewall, wherein one side of each terminal firewall is connected with a corresponding vehicle-mounted subsystem controller, and the terminal firewalls are used for filtering the data entering / exiting from the vehicle-mounted subsystem controller; and a switch firewall which is connected with the other side of the corresponding terminal firewall and is used for filtering data transmitted between the vehicle-mounted subsystem controllers, wherein the switch firewall is connected with an automobile electronic control unit and is used for filtering data of the in / out electronic control unit. According to the invention, the firewall is deployed according to the network architecture of the vehicle-mounted Ethernet, the protection requirement of communication data is realized in parts, the automobile attack defense effect is improved, and the safety of data transmission of the vehicle-mounted Ethernet is ensured.

Description

technical field [0001] The invention relates to the technical field of automotive communication security, in particular to a vehicle-mounted Ethernet firewall system, a method and a device for determining communication delay. Background technique [0002] The development of networking has made more and more cars connected to the Internet, especially after the emergence of vehicle Ethernet, which provides convenience for enriching vehicle functions and is also more and more affected by network security attacks. For example, in some attack cases, it is possible to interfere with the normal driving of the car, control the car from the inside, and even connect the car through remote services and take control away from the driver. If such a thing happens on a large scale, it will be a threat to the entire The disaster of the automobile industry, therefore, network security protection is particularly important for today's automobiles. [0003] In the related technology, the on-bo...
