V2X Internet-of-vehicles safety communication system and method based on 5G

Abstract

The invention relates to a V2X Internet-of-vehicles safety communication system and method based on 5G. The V2X Internet-of-vehicles safety communication system comprises a cloud terminal, a vehicle terminal, a road side terminal and at least two pedestrian terminals, wherein the sum of the number of the road side terminals and the number of the pedestrian terminals is at least two; the cloud terminal comprises a certificate server, a cloud security module and an Internet-of-vehicle server; the vehicle end comprises a vehicle end short-distance direct communication module, a vehicle end 5G communication module, a vehicle terminal safety module and a vehicle terminal control module; the roadside end comprises a roadside end short-distance direct communication module, a roadside end 5G communication module, a roadside terminal safety module and a roadside terminal control module; the pedestrian terminal comprises a pedestrian end short-distance direct communication module, a pedestrian end 5G communication module, a pedestrian end safety module and a pedestrian end control module; V2X Internet-of-vehicles identity authentication and group security encryption communication are realized according to the characteristics of 5G and V2X Internet-of-vehicles, so that the V2X Internet-of-vehicles identity authentication and group security encryption communication are safe, reliable, simple and efficient.

Description

technical field [0001] The invention belongs to the technical field of V2X Internet of Vehicles communication, and in particular relates to a 5G-based V2X Internet of Vehicles secure communication system and method that can realize secure encrypted communication of the V2X Internet of Vehicles. Background technique [0002] Vehicle to Everything (V2X) is a new generation of information and communication technology that connects vehicles to everything. It is a general term for a series of vehicle communication technologies. V2X mainly includes Vehicle to Vehicle (V2V), Vehicle to Infrastructure (V2I), Vehicle to Pedestrian (V2P), Vehicle to Network (V2N). ) and other modes. V2X is a key technology for future intelligent transportation. It can obtain a series of traffic information such as real-time road conditions, road information, and pedestrian information through communication, improve driving safety, reduce congestion, improve traffic efficiency, and provide in-vehicle ...

AI Technical Summary

Problems solved by technology

[0003] However, while V2X brings convenience, quickness and practicality to the communication among vehicles, traffic roadside infrastructure and pedestrians (hereafter, vehicles, traffic roadside infrastructure and pedestrians are referred to as V2X communication parties for short), there are also disadvantages that cannot be ignored. security risks

For example, the identities of all parties in V2X communication are counterfeited, and the information transmitted between parties is eavesdropped, tampered with, replayed, etc. These security threats are likely to cause major accidents, serious economic losses or other adverse effects, and damage the lives and properties of relevant users. Security and Privacy Poses Serious Threats

At the same time, in the V2X Internet of Vehicles environment, the storage resources and processing capabilities of the V2X communication parties themselves are limited (such as data and communication processing capabilities, storage capabilities, etc.), and it is impossible to predict and pre-set the use of Public key certificates or public keys of all possible (possibly infinite) other parties to the authentication
