A method of dissemination of malicious information in automobile network based on infectious disease model

Abstract

The application discloses a vehicle network malicious information transmission method based on an epidemic model, comprising: a first step of building an ICV (Intelligent Connected Vehicle) model structure, wherein the ICV model structure comprises a physical layer used for describing physical features of a vehicle and a network layer used for describing information transmission features; a secondstep of introducing a vehicle dynamic model, and for the physical layer, using an IDM (Intelligent Driver Model) to describe movement of the vehicle; and a third step of introducing an epidemic transmission model, and for the network layer, using an epidemic model SIR (Susceptible-Infected-Recovered) to describe transmission of in-vehicle network malicious information. The vehicle network malicious information transmission method of the invention has the beneficial effects that: a two-layer structure model is provided for the ICV, dynamics behaviors of the vehicle are studied at the physicallayer, information infection and transmission behaviors of the vehicle are studied at the network layer, and description is performed on transmission behaviors of in-vehicle network malicious information or threat information at present, thereby solving the problem that there is no research on transmission of the in-vehicle network malicious information at present.

Description

technical field [0001] The invention relates to the technical field of automobile network security, in particular to a method for disseminating malicious information on automobile networks based on an infectious disease model. Background technique [0002] At present, a new round of technological change represented by the Internet of Everything, big data and artificial intelligence is in the ascendant, leading the overall transformation and upgrading of traditional industries and promoting the restructuring of the industrial structure. Smart cars and smart transportation are the products of this change. Different from traditional cars, mobile Internet cars not only include the traditional internal network for maintaining the basic functions of the car, but also include the off-vehicle communication system for mobile communication, which is used to provide the car with the vehicle, the vehicle and the infrastructure, and the vehicle and the vehicle.
