A simulation experiment platform for research on privacy protection of Internet of Vehicles

Abstract

The invention discloses a simulation experiment platform oriented to research on privacy protection of the Internet of Vehicles. The platform includes a synthetic traffic data set, a SUMO vehicle movement simulator, a vehicle communication simulation module, a privacy protection algorithm module and a traffic state visualization module. The synthetic traffic data set is composed of real traffic data, vehicle simulation data and road network structure data, providing road and vehicle information; SUMO vehicle movement simulator is used to simulate the movement of microscopic vehicles, including vehicle following and lane changing models, and for each vehicle Set an independent driving route; the vehicle communication simulation module is used to simulate the communication process of sending and receiving beacon signals between vehicles and the interaction between vehicles and service centers; the privacy protection algorithm module is sensitive to vehicle ID, location, speed, etc. by implementing typical privacy protection algorithms The information is protected; the traffic status visualization module is used to display the traffic status before and after privacy protection, and then show the impact of privacy protection on traffic.

Description

technical field [0001] The invention relates to the field of vehicle networking technology communication and security, especially for the privacy protection of vehicle ID, position, speed and other sensitive information in vehicle-vehicle and vehicle-cloud communication and the construction of an experimental platform. Background technique [0002] In recent years, the Internet of Vehicles technology has been greatly promoted under the development of the Internet of Things and the new generation of communication technology. The Internet of Vehicles organically connects "people, vehicles, roads, and clouds", which can not only obtain more perceptual information than a single vehicle, enhance safe driving, and promote the innovation and application of autonomous driving; it is also conducive to the construction of an intelligent transportation system , which is of great significance to improving traffic efficiency, improving driving experience, energy saving and emission reduc...

AI Technical Summary

Problems solved by technology

[0006] (1) Lack of large-scale simulation experiment verification, usually only to verify the performance of the implemented algorithm, and cannot prove that it can be extended to actual vehicles and traffic;

[0007] (2) The uncertainty of traffic makes it difficult to model, and it is impossible to directly analyze the impact of privacy protection algorithms on traffic flow and data fusion from a theoretical level, as well as the impact of different road network structures or traffic flow on privacy protection effects;

[0008] (3) Lack of improvement and promotion of privacy protection algorithms from the experimental point of view, such as analyzing which pseudonym switching can provide the best privacy protection effect from the experimental point of view
