Message transmission method and device, electronic equipment and storage medium

Abstract

The embodiment of the invention discloses a message transmission method and device, electronic equipment and a storage medium. The method is applied to a CAN node driver in communication connection with a gateway controller. The gateway controller is also in communication connection with at least one Ethernet node. The method comprises the steps of when a to-be-sent message is received, determining whether an identifier of the to-be-sent message belongs to a preset white list or not; and if the identifier of the to-be-sent message belongs to the preset white list, sending the to-be-sent message, otherwise, stopping sending the to-be-sent message. According to the technical scheme of the embodiment of the invention, the safety of message transmission is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of automotive electronics, and in particular, to a message transmission method, device, electronic equipment, and storage medium. Background technique [0002] As an independent functional entity, a traditional car's internal network mostly adopts a closed distributed network. Among them, CAN\LIN bus is the representative. However, with the continuous development of network technology, information technology and controller technology, automobiles are increasingly emphasizing intelligence and interconnection. In recent years, with the rise and development of V2X (vehicle to everything, information exchange between vehicles and the outside world), vehicle Ethernet, as the core of the entire network, has become more and more popular with the traditional CAN distributed network. [0003] In the prior art, since the CAN bus network is an internal closed network, its security is not conside...

AI Technical Summary

Problems solved by technology

However, the addition of vehicle Ethernet makes it possible for the CAN bus to be exposed to the public network, and there is a risk of remote intrusion

However, the existing Ethernet security issues often prevent untrusted network access through the network firewall of the operating system.

However, because most of the network nodes in the car are embedded devices, it is impossible to mount a powerful operating system, and it is impossible to directly borrow traditional network firewalls.

[0004] Therefore, a method is needed to solve the problem of secure transmission of the above-mentioned vehicle-mounted network in the vehicle-mounted embedded environment
