In-vehicle heterogeneous network security communication control method, computer equipment and storage medium

Abstract

The invention belongs to the technical field of communication network security, and discloses an in-vehicle heterogeneous network security communication control method, computer equipment and a storage medium, a node participating in in-vehicle network data transmission completes node identity registration of in-vehicle heterogeneous network security communication control under the assistance of an in-vehicle gateway; and the nodes participating in the in-vehicle network data transmission complete in-vehicle network node identity authentication. The invention provides an in-vehicle network node identity registration method and an in-vehicle network node identity authentication method in combination with the characteristics of complex isomerization, multiple network node types, missing of identities, multiple authentication scenes, serious limitation of resources such as computing bandwidth and the like of intelligent vehicle-mounted software and a network architecture. The mutual authentication between the vehicle internal network entities is realized, the problem of node authentication of the vehicle internal network in a resource limited scene is solved, and the legality of the external access entity and the internal network node is ensured.

Description

technical field [0001] The invention belongs to the technical field of communication network security, and in particular relates to an in-vehicle heterogeneous network security communication control method, computer equipment and storage medium. Background technique [0002] At present, with the rapid development of intelligent networked vehicles, the number of new-generation intelligent networked vehicles represented by new energy vehicles has increased sharply, and the security protection of heterogeneous networks inside vehicles has also become a major problem that cannot be ignored. Due to the diverse types of network nodes, the lack of identity identifiers, the diverse authentication scenarios, and the severe limitation of computing bandwidth and other resources, the secure communication of the vehicle's internal network is under great threat, which seriously affects the driving safety of the car and brings people's lives and property. security poses a potential threat....

AI Technical Summary

Problems solved by technology

[0004] Through the above analysis, the existing problems and defects of the existing technology are: the existing technology does not fully consider the characteristics of the internal network heterogeneity, interface openness, and ECU variety of intelligent driving vehicles, and cannot perform a unified identity for multiple types of network nodes. Management, lack of comprehensive and multi-level entity identity authentication protocol and network node key agreement mechanism
