Method and device for generating images in batches through network traffic

Abstract

The invention provides a method and a device for generating images in batches by network traffic, which can efficiently generate images in batches from original network traffic data. The method comprises the following steps: acquiring an original network traffic data set and a corresponding category label; initializing the height H and the width W of the network flow generation image, and optimizing the H and the W according to the requirements of the classification model on the input image, wherein H is used for reflecting network flow time and space characteristic information, and W is usedfor reflecting a network flow characteristic number; and performing data extraction on the original network traffic data set by adopting a window-based data extraction algorithm according to the optimized H, and generating a grayscale image corresponding to the extracted data set according to the optimized H and W to obtain a network traffic image set. The method is applied to the field of networksecurity.

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...
