Abstract
The present disclosure belongs to the technical field of security of the Internet of vehicles, and discloses an intrusion detection method and device for an in-vehicle controller area network. The method of the present disclosure includes: digitizing and normalizing collected original data, obtaining preprocessed data, and dividing the preprocessed data into a training set and a test set; conducting feature selection on the preprocessed data through a particle swarm optimization (PSO)-light gradient boosting machine (GBM) bidirectional feature selection method; and classifying test set data subjected to the feature selection with a stacking integrated model, and obtaining an intrusion detection result. The present disclosure is configured to efficiently and accurately detect intrusion information appearing in the in-vehicle controller area network, and prevent security incidents of the Internet of vehicles caused by intrusion into the in-vehicle controller area network.
