Abstract

The present invention provides a method and device for acquiring information of Internet of Things equipment. The method includes: acquiring device information of some IoT devices according to the acquired traffic data sequence and its corresponding relationship with the IoT devices, dividing the device information into a preset number of traffic patterns with known traffic characteristics of the IoT devices, and Obtain the device information respectively the traffic characteristics of the known IoT devices and the device information The traffic characteristics of the unknown IoT devices are the mode distribution vectors on these traffic patterns, according to the device information unknown IoT devices and device information The mode distribution of known IoT devices Vector similarity, the device information of the known IoT device corresponding to the maximum similarity value is used as the device information of the unknown IoT device, so that the device information of the IoT device can be obtained efficiently and the traffic to the cloud platform can be overcome. It is a time-consuming and labor-intensive problem to analyze the rules to obtain the device information of the corresponding IoT devices.

Description

technical field [0001] The present invention relates to the field of Internet technology, and more specifically, to a method and device for acquiring information of Internet of Things equipment. Background technique [0002] The Internet of Things, that is, the Internet where things are connected, can connect different Internet of Things devices for information exchange to achieve specific functions. When the IoT devices in the Internet of Things are connected to the cloud platform, the interaction with cloud applications and the interaction between IoT devices can be realized. Due to potential attacks in the network, IoT devices connected to the cloud platform have security risks. To this end, each cloud platform usually uses a traffic security analysis system to detect potential network security risks based on data analysis. In view of the large differences in the specific technical means adopted by each cloud platform and the uneven traffic security analysis capabilitie...
