Worm hole attack detection method and device based on Internet of Things

The invention relates to a wormhole attack detection method and device based on the Internet of Things, and belongs to the field of Internet of Things security, and the method comprises the steps: judging whether an equipment end is in an abnormal state or not, and recognizing the equipment end which is potentially attacked by a wormhole, thereby facilitating the accurate obtaining of data used for constructing a wormhole detection model, and improving the detection accuracy. A wormhole detection model is established to ensure that the model is matched with an equipment end. By updating the wormhole detection model, the updated model can be suitable for all the equipment ends of the Internet of Things, the wormhole attack detection efficiency and reliability of all the equipment ends of the Internet of Things are improved, and the data independence and privacy among different equipment ends are ensured. And the wormhole detection model is issued to each device end to realize real-time wormhole attack detectio
