Vehicle networking authentication method facing vehicle differentiation

Abstract

The invention discloses a vehicle networking authentication method facing vehicle differentiation. In the method, a secret key management center gives a unique identifier to a public vehicle and gives a digital certificate to a private vehicle so that the vehicles with different privacy requirements are separated. After a running vehicle passes through first identity authentication and enters into a new RSU communication scope, through extracting information of a speed and the like recorded in a vehicle-mounted OBU memory module and sending to an RSU communication module, an RSU calculating module verifies a relation among a geographic position, the speed and current traffic density so as to determine that a vehicle running process possesses consistency, a vehicle identity is recorded and verified and authentication is completed again. In the invention, based on a dedicated short range communication technology (DSRC), a digital certificate and a certificateless aggregation scheme, authentication efficiency is effectively increased, forgery attack difficulty is enhanced and a certificate management burden is reduced.

Description

technical field [0001] The invention relates to the field of vehicle networking technology and wireless communication technology, in particular to a vehicle networking authentication method oriented to vehicle differentiation. Background technique [0002] Among the 100 major projects drafted in the "Thirteenth Five-Year Plan", the 54th item is "accelerating the construction of the Internet of Vehicles and the Internet of Ships". It can be seen that the Internet of Vehicles has been regarded as a major development goal at the government level, and security is particularly important based on the Internet of Vehicles technology. In recent years, various Internet of Vehicles security issues have become increasingly exposed. For example, in 2011, a research report by computer experts from the University of California and the University of Washington pointed out that hackers can remotely control the engine, brakes and even other functions of the car. In July 2015, two well-know...

AI Technical Summary

Problems solved by technology

In the IoV based on DSRC communication technology, the vehicle is connected through the on-board OBU and the drive test system RSU, but the connection cannot be maintained all the time, and the connection is intermittent, because the RSU is a single device and its communication range is short

And every time information exchange with RSU, identity authentication is required, which obviously reduces the quality of communication

In terms of authentication methods, digital certificates are also used for identity authentication, but the current number of cars in my country is 140 million, which will undoubtedly greatly increase the burden of key management and certificate management, and also reduce the efficiency of authentication
