Internet of Vehicles Sybil attack detection method, device and apparatus and storage medium

Abstract

The invention relates to the technical field of Internet of Vehicles, and discloses an Internet of Vehicles Sybil attack detection method, device and apparatus and a storage medium, and the method comprises the steps: obtaining the state information of a target vehicle, building a physical feature model according to the state information, obtaining the movement track of the target vehicle, carrying out the similarity analysis according to the movement track of the target vehicle, obtaining similarity feature vectors according to a preset similarity detection model, inputting the similarity feature vectors into a movement behavior detection model obtained through training to obtain similarity feature vectors with close distances, and taking vehicles corresponding to the similarity feature vectors with close distances as malicious vehicles attacked by Sybil. The physical feature model completely records the driving track of the target vehicle, the similarity feature vectors with close distances are obtained through the moving behavior detection model, the detection accuracy is improved, malicious vehicles with Sybil attacks are detected, the technical problem that whether Sybil attacks exist in Internet of Vehicles applications or not cannot be detected in the prior art is solved, and the security of Internet of Vehicles is improved.

Description

technical field [0001] The present invention relates to the technical field of the Internet of Vehicles, in particular to a method, device, device and storage medium for detecting Sybil attacks in the Internet of Vehicles. Background technique [0002] With the development of autonomous driving technology, car networking technology has become an important part of people's transportation. The Internet of Vehicles communication enables vehicles to share road traffic information through mutual communication, and then automatically make driving decisions based on the information provided by all parties, thereby further ensuring traffic safety and travel efficiency. While the Internet of Vehicles provides convenience for people, there are also some security risks. In the online car-hailing application, since the user's choice of vehicle often needs to be carried out on the network, it is difficult to judge whether the vehicle displayed on the network is real or fabricated by the...
