Sybil attack detection method and system based on ADAS of Internet of Vehicles

The invention discloses a Sybil attack detection method and system based on an ADAS of the Internet of Vehicles. A receiver vehicle and a sender vehicle collect data in the driving process and generate data packets containing snapshots at three different moments respectively; performing timestamp verification on the snapshots at the same moment in the receiver vehicle data packet and the sender vehicle data packet, performing method position verification on the snapshots at the same moment, and performing surrounding environment object verification on the snapshots at the same moment to respectively obtain a timestamp verification result, the actual position of the sender vehicle and surrounding environment objects of the two vehicles; and after verification, detecting whether a Sybil attack exists. According to the method, extra hardware support is not used, the effect of detecting whether the vehicle initiating communication has the Sybil attack or not is ensured based on ADAS sensors equipped on most of th
