This invention discloses an encrypted video recognition method in a Tor environment, comprising four steps: traffic acquisition, ADU-burst length sequence extraction, upstream feature extraction, and downstream task classification. First, real-time Tor traffic is captured from the network information service center at the local area network entry point. Then, based on the characteristics of Tor video traffic, features are extracted using the corresponding TREFS iT segmentation strategy to obtain the encrypted ADU-burst length sequence. Next, a 1DCNN model is used for noise filtering and secondary feature extraction. Finally, random forest is used for classification. This method proposes an encrypted video recognition approach for the complex environment of Tor. It does not require decryption of the encrypted video; it can identify videos played by clients through the Tor network based on video traffic characteristics for the purpose of monitoring harmful videos. It has wide application scenarios and good monitoring effects.
