Abstract

The invention discloses a lightweight anonymous authentication method with privacy protection based on the Internet of Vehicles, which includes: an initialization step, a private key generation step for a vehicle communication unit, a confidential information generation step that can be anonymously authenticated, an information decryption and verification step, and an anonymous authentication step. Identity Tracing Steps. The invention generates anonymous identity and private key of anonymous identity for intelligent vehicles through trusted center, combines ElGamal encryption algorithm and modified Schnorr signature algorithm to generate anonymous information, and realizes encrypted transmission of transmitted information in authentication protocol , only the private key of the roadside base station unit can be decrypted; when a dispute arises, the anonymous identity can also be tracked, which has important practical application prospects.

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...
