Method and device for generating images in batches from network traffic

Abstract

The present invention provides a method and device for generating images in batches from network traffic, which can efficiently generate images in batches from original network traffic data. The method includes: obtaining the original network traffic data set and corresponding category labels; initializing the height H and width W of the image generated by the network traffic, and optimizing H and W according to the requirements of the classification model for the input image; wherein, H It is used to reflect the time and space characteristic information of network traffic, and W is used to reflect the characteristic number of network traffic; according to the optimized H, the window-based data extraction algorithm is used to extract data from the original network traffic data set, and according to the optimized H and W Generate a grayscale image corresponding to the extracted data set to obtain a network traffic image set. The invention is applied in the field of network security.

Description

technical field [0001] The present invention relates to the field of artificial intelligence, in particular to a method and device for generating images in batches from network traffic. Background technique [0002] With the development of artificial intelligence technology, the application of deep learning in the field of network security is also increasing. However, the original network traffic data cannot meet the input requirements of some deep learning models, which limits the further development of deep learning technology in the field of network security. Therefore, the existing technology performs complex calculations such as covariance calculation or Euler transformation through the correlation information between network traffic features, and generates network traffic data as a grayscale image to meet the input requirements of the classification model. However, the existing technology has high complexity and a large amount of calculation, and most methods only gen...
