Abstract

The invention discloses a lightweight anonymity authentication method with privacy protection and based on Internet of Vehicles. The method comprises the steps of initialization, generation of a private key of a vehicle-mounted communication unit, generation of secrecy information capable of anonymity authentication, information decryption and verification, and tracking of anonymous identity. A trustable center generates an anonymous identity for an intelligent vehicle as well as the private key of the anonymous identity, an ElGamaL encryption algorithm and a modified Schnorr signature algorithm are combined to generate the information capable of anonymity, transmission information is transmitted in an encrypted way in authentication protocols, and the information cannot be decrypted unless using the secret key of a roadside base station unit; when a dispute of a traffic accident occurs, the anonymous identity can be tracked; and the method has prospects in practical application.

Description

technical field [0001] The invention relates to the technical field of wireless communication of the Internet of Vehicles, in particular to a lightweight anonymous authentication method with privacy protection based on the Internet of Vehicles. Background technique [0002] Intelligent vehicle networking is composed of fixed network facilities, network management centers, roadside network access points, mobile nodes (such as vehicles equipped with communication equipment and sensors) and wireless network connections between them. The most important and important service of smart car networking is to provide smart driving and traffic safety. However, there are a large number of problems and hidden dangers in the intelligent vehicle network. Before these problems are not resolved, it is difficult to really deploy the intelligent vehicle network. Since the intelligent vehicle network is a mobile vehicle self-organizing network, and most of the groups are ordinary vehicle users...
