Abstract

The invention relates to the technical field of behavior detection, and provides an abnormal behavior detection method and device and a verification system. The abnormal behavior detection method comprises the following steps: receiving a to-be-detected behavior from a block chain node; using a first detection model and a second detection model to perform detection based on to-be-detected behaviors to obtain a first detection result and a second detection result respectively, wherein the first detection model is obtained after unsupervised learning based on the normal behavior sample set, andthe second detection model is obtained after supervised learning based on the normal behavior sample set and the abnormal behavior sample set; determining a final detection result according to the twodetection results; and sending the final detection result to the block chain node, so that the block chain node forwards the function request sent by the source equipment to the target equipment whenthe final detection result is normal, otherwise, refusing to forward the function request to the target equipment. According to the method, the abnormal linkage behavior of the equipment can be effectively detected, and the safety of the equipment is improved.

Description

technical field [0001] The present application relates to the technical field of behavior detection, and in particular, to a method, device and verification system for abnormal behavior detection. Background technique [0002] Due to the characteristics of de-multiplexing, information sharing, data immutability, and good encryption, blockchain has been applied in the field of Internet of Things in recent years. For example, the problem of mutual trust between devices belonging to different platforms can be solved by establishing a consortium chain, so that these devices can be linked across platforms. However, there is still no effective detection method for abnormal linkage behaviors of devices (including but not limited to malicious behaviors), which leads to potential threats to the security of the devices. SUMMARY OF THE INVENTION [0003] In view of this, the embodiments of the present application provide an abnormal behavior detection method, device, and verificatio...
