Embodiment 1

[0069] figure 1 It is a schematic flowchart of a storage file and network data stream encrypted communication detection method provided by the embodiment of the present invention. The method is implemented based on a deep convolutional neural network (CNN), and is suitable for detecting whether data is encrypted. Such as figure 1 As shown, the method may specifically include the following steps:

[0070] Step 110: Convert each byte of the data in the data set into a pixel value to obtain a grayscale image corresponding to each data.

[0071] In this embodiment, the file type corresponding to the data in the data set is at least one of storage files and network data stream files; the data type of storage files is at least one of video data, audio data and text data; network data stream The data type of the file is at least one of network browsing traffic data and FTP transmission traffic data. Optionally, after acquiring the data set, convert the data in the data set into a ...

Abstract

The invention discloses a storage file and network data flow encryption communication detection method and system, and the method comprises the steps: carrying out the byte conversion of to-be-detected data, and obtaining a two-dimensional gray image corresponding to the to-be-detected data, wherein the to-be-detected data is storage file data or network data stream data; inputting the two-dimensional grayscale picture into a pre-trained encrypted communication detection model, and outputting a result of whether the to-be-detected data is encrypted or not, wherein the encrypted communication detection model comprises a feature extraction module and a feature mapping module, the feature extraction module is used for carrying out feature extraction on a two-dimensional grayscale image to obtain an information correlation feature map of the two-dimensional grayscale image, and the feature mapping module is used for carrying out feature mapping on the information correlation feature map toobtain a result of whether the to-be-detected data is encrypted or not. According to the method, the network input problem can be solved, automatic feature extraction is realized, whether the data isencrypted or not is judged, the classification precision is improved while complex feature extraction is avoided, and the method and system are suitable for various types of data.

Description

technical field [0001] The invention relates to the field of information security, in particular to a storage file and network data flow encrypted communication detection method and system. Background technique [0002] In the era of computer and network communication, information is easily obtained, copied and disseminated. Therefore, encrypted communication technology has gained a wide range of applications in the information age. In fact, in recent years, with the increase of Internet penetration rate and the improvement of people's awareness of privacy protection and information security, encrypted communication technology has been widely and deeply used in all aspects of people's daily life. [0003] Encrypted communication technology can provide legal users with data security protection, for example, encrypt important files stored in their own computers to prevent browsing and theft, and encrypt files before transmitting them through communication tools, etc. However,...
