Abstract

The invention discloses a method and a device for identifying network equipment. The method comprises the following steps: acquiring a target data stream sent by target network equipment in a preset time period; extracting an atomic time field of the target data stream to obtain a target fingerprint of the target network device; classifying the target fingerprint by using a plurality of trained support vector machines to obtain a target classification result of the target network device, the target classification result comprising a multi-bit coded value, the multi-bit coded value being in one-to-one correspondence with the support vector machines; and matching the target classification result with a plurality of preset classification results to obtain an identification result of the target network device, the plurality of preset classification results being in one-to-one correspondence with the plurality of categories, and each preset classification result comprising a multi-bit preset coded value. According to the invention, the technical problem that the efficiency of identifying the network equipment is too low in related technologies is solved.

Description

technical field [0001] The present invention relates to the field of network equipment identification, in particular to a network equipment identification method and device. Background technique [0002] The Internet has penetrated into all aspects of people's lives. Large-scale network coverage inevitably requires a large number of terminal devices. In order to avoid serious consequences caused by maliciously damaged devices illegally accessing the network, it is necessary to effectively identify network terminal devices and ensure network security. Safe and reliable space environment. [0003] The existing device identification method is to identify the fingerprint of the device. The device fingerprint is a device feature or a unique device identifier that can be used to uniquely identify the device. Therefore, it is very important to select the feature that generates the device fingerprint. Taking into account stability, uniqueness and security; the feature fields select...
