Abstract

The invention discloses a network flow identification method and device. The method comprises the following steps: acquiring a data packet of target network traffic to be identified; enhancing the data packet through wavelet transform and histogram equalization; the enhanced data packet is input into a recognition model, the type of the target network traffic is output by the recognition model, the recognition model comprises a residual module and an attention module, the recognition model is formed by training multiple sets of training data, and each set of training data comprises the input data packet of the network traffic and the type of the network traffic. According to the invention, the technical problem of low identification accuracy of the traditional network flow identification method in the related technology is solved.

Description

technical field [0001] The present invention relates to the field of traffic identification, in particular to a network traffic identification method and device. Background technique [0002] With the popularity of the Internet, the number of Internet users has shown a blowout growth. At present, traffic encryption technology exists in all walks of life in society, bringing practical solutions to various applications with high privacy requirements such as distance education, online consultation, and video calls. Various websites have also generally begun to adopt the HTTPS protocol to ensure that they are not maliciously attacked. In search engines such as Google, websites using the HTTPS encryption protocol will be ranked first. However, technology is a double-edged sword. Traffic encryption technology is also used as a tool to disrupt network security. The abuse of encrypted traffic will bring a lot of hidden dangers to cyberspace security and network operation and main...
