Embodiment Construction

[0033] In the following, only certain exemplary embodiments are briefly described. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present application. Accordingly, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0034] The embodiment of the present application provides a communication method, figure 1 A flowchart showing a communication method according to an embodiment of the present application. The communication method can be applied to an electronic control unit (Electronic Control Unit, ECU) in a vehicle. The structure of the electronic control unit in the vehicle may include: a central gateway (Central gateway, CGW) is connected to multiple buses, and each bus is connected with one or more electronic control units.

[0035] For example, the bus may include a Controller Area Network (CAN) bus or a CANFD ...

Abstract

The present application proposes a communication method, device, electronic device and readable storage medium. A central gateway is connected to multiple buses, and each bus is connected to one or more electronic control units. The communication method is applied to electronic control units, including: receiving The synchronization message sent by the central gateway; among them, the current fresh value of the central gateway contained in the synchronization message; the synchronization message is verified; in the case of passing the verification synchronization message, according to the freshness in the synchronization message value updates the current fresh value of the electronic control unit. The present application can realize the synchronization of the fresh value of each electronic control unit, and avoid communication verification failure.

Description

technical field [0001] The present application relates to the technical field of vehicles, and in particular, to a communication method, apparatus, electronic device and readable storage medium. Background technique [0002] The communication security of in-vehicle network has been paid more and more attention. Because the electronic control unit (ECU) firmware in the car is refreshed, the parts are replaced, or the bus is attacked by a third-party device, the bus messages are tampered, replayed and counterfeited, and the vehicle ECU receives incorrect signals. The vehicle drives normally. Among them, the replay attack means that the attacker sends a packet that the target has received to achieve the purpose of deceiving the target. [0003] In order to reduce the risk of repeated attacks, the freshness value can be added to the message of the vehicle bus, but if the consistency of the freshness value of the electronic control unit on the bus is poor, it will cause the com...
