V2I Internet-of-Vehicles identity authentication system and method

Abstract

The invention provides a V2I Internet-of-Vehicles identity authentication system and method. The V2I Internet-of-Vehicles identity authentication system comprises a cloud end, at least one roadside end and at least one vehicle end, the cloud comprises a traffic management cloud server, a certificate server and a third security module; each roadside end comprises a roadside server, a roadside unitand a second security module; the vehicle terminal comprises a vehicle-mounted unit and a first safety module. The traffic management cloud server is connected with the certificate server and the third security module. When identity authentication is carried out on the cloud, the roadside end and the vehicle end, identity authentication is carried out. According to the embodiment of the invention,the cloud is adopted to respectively carry out identity authentication on the roadside end and the vehicle end, and then the roadside end and the vehicle end respectively carry out identity authentication on the cloud, so that direct mutual authentication between the vehicle end and the roadside end is avoided, and the consumption of vehicle end resources and the burden of processing related information by the vehicle end are reduced.

Description

technical field [0001] The present invention relates to the technical field of V2I Internet of Vehicles communication, in particular to a V2I Internet of Vehicles identity authentication system and method. Background technique [0002] Vehicle to Everything (V2X) is a new generation of information and communication technology that connects vehicles with everything, and 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 several 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 information. [0003] Among them, V2I refers to the communication...

AI Technical Summary

Problems solved by technology

[0004] However, while V2I brings convenience, quickness and practicality to the communication between vehicles and roadside infrastructure, there are also potential safety hazards that cannot be ignored.

For example, the identity of the V2I vehicle end and / or roadside end is counterfeited, and the information transmitted between the vehicle end and the roadside end is intercepted, tampered with, replayed, etc., which is likely to cause major accidents to V2I vehicles or roadside infrastructure , serious economic loss or other adverse effects, and a serious threat to the life, property safety and privacy of relevant users

At the same time, in the V2I Internet of Vehicles environment, a vehicle may pass through multiple roadside infrastructures in a period of time, the vehicle has high mobility, and the relationship between the vehicle and the roadside infrastructure has high Dynamic, and the vehicle itself has limited processing capabilities and resources (such as data and communication processing capabilities, storage capabilities, etc.), it is impossible to pre-set all the (possibly infinite) procedures that will be passed through the vehicle for authentication. The public key certificate of the roadside infrastructure, and because the driving of the vehicle is dynamic, the driving direction and path may change at any time, so in fact it is impossible to completely predict which roadside infrastructure the vehicle needs to pass through, and it is even more impossible to predict If the vehicle temporarily downloads the public key certificate of the roadside infrastructure every time it passes through a roadside infrastructure and then performs authentication, it will not only give the vehicle It will cause pressure on communication and calculation, and will also cause delays in authentication, affect the effect of authentication, and even cause authentication failure, and make subsequent secure encrypted communications impossible
