Efficient condition privacy protection and security authentication method in internet of vehicles

Abstract

The invention discloses an efficient condition privacy protection and security authentication method in an internet of vehicles. The efficient condition privacy protection and security authentication method comprises the following steps of: system initialization, generation of pseudonym identities and signature private keys of vehicles, signing and authentication of a message and tracing of real identities of the vehicles. The vehicles carry out cooperative communication with surrounding vehicles and roadside units deployed at both sides of a road by on-board units assembled on the vehicles, driving security of the vehicles can be effectively improved, and vehicle users can more conveniently and rapidly acquire related traffic services. The efficient condition privacy protection and security authentication method disclosed by the invention not only can meet security requirements in the internet of vehicles, but also optimizes the computing process of signature generation and verification in the communication. The efficient condition privacy protection and security authentication method is greatly improved on the aspect of efficiency of computing cost, communication cost and the like, and is more applicable to communication and application in the internet of vehicles.

Description

technical field [0001] The invention relates to the Internet of Vehicles and wireless communication technology, in particular to an efficient conditional privacy protection and security authentication method in the Internet of Vehicles. Background technique [0002] Vehicles have become a means of transportation that almost every family will use, and in all walks of life, such as police cars, ambulances, large trucks and other different types of large or small vehicles are all over the city's traffic roads. The rapid increase in the number of vehicles has brought many problems, such as more and more frequent traffic accidents, traffic congestion during the rush hour in big cities, traffic management by the Vehicle Supervision Bureau and the traffic department, etc. To solve these problems, research on vehicle networks and intelligent transportation systems is becoming more and more extensive. By equipping each vehicle with an on-board unit (OBU) that can communicate wireles...

Second, the scheme cannot satisfy undeniable

[0007] In 2015, Horng et al found some security loopholes in Lee and Lai's scheme

Recently, Bayat et al. and He et al. also proposed their own improved security authentication schemes based on Lee and Lai's scheme, but the cryptographic related operations required for the signature and authentication processes in the schemes are complex and require too much computing overhead.

In the case of high vehicle density, traffic congestion, and large amount of communication information on the roads in the city center, it is easy to become the bottleneck of network communication
