Description

technical field

[0001] The invention relates to the technical field, in particular to a Sybil attack detection method with traceable identity in the Internet of Vehicles environment. Background technique

[0002] As an important part of the modern intelligent transportation system, the Internet of Vehicles (VANET) mainly obtains vehicle, vehicle owner, road attribute information, and dynamic and static information during vehicle driving through various vehicle sensors, and realizes the connection between people and vehicles through various communication technologies. , Vehicle-to-vehicle, vehicle-to-roadside infrastructure information exchange and sharing, thereby improving road safety and traffic operation efficiency.

[0003] The basic structure of the VANET system is mainly composed of three main parts: trusted center (TA), roadside unit (RSU), and on-board unit (OBU):

[0004] (1) The Trusted Center (TA) is the highest authority in VANET, connected with the Roadside Uni...
