A method for safe communication of Internet of Vehicles

Abstract

The invention relates to a secure communication method for the V2X network of vehicles that can realize secure encrypted communication in the V2X network of vehicles. Through an identity-based public key cryptography system, a safe and efficient group session key negotiation protocol is proposed to establish a protocol between parties involved in V2X communication. The group session key used for secure communication solves the problem of secure communication between V2X communication parties in the V2X Internet of Vehicles environment; through ultra-high reliability and ultra-low latency communication during the group session key negotiation process The 5G network generates the system parameters required for negotiation by the cloud, and provides the required relevant data for each participant, and assists all parties to solve the problem of identity authentication in the process of group session key negotiation. The present invention is based on 5G and V2X The characteristics of the Internet of Vehicles realize the V2X Internet of Vehicles identity authentication and group security encrypted communication, which effectively solves the problem of insufficient security in the existing technology, making the V2X Internet of Vehicles identity authentication and group security encrypted communication safe, reliable, simple and efficient.

Description

technical field [0001] The invention belongs to the technical field of Internet of Vehicles communication, and in particular relates to a secure communication method for the Internet of Vehicles 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 entertainment inform...

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
