Abstract

The present invention provides a keyword-based network trajectory classification method and device. The classification method first obtains the first trajectory cluster by combining the flow statistics feature with the K-means method, and uses each cluster of the first trajectory cluster as the trajectory segmentation method. Input, divided into fixed field IF and variable field VF, and calculate the length of each fixed field and the location information of the fixed field; then use the IF distribution fitting method to perform curve fitting to obtain the IF position distribution curve; then use the IF classification method to obtain The type of IF contained in each extreme value interval and the quantity of various IFs, and then the type of IF contained in each extreme value interval and the quantity of various IFs are input into the trajectory clustering method, and the second trajectory cluster is output, and then The delimiter is inferred by the keyword inference method, and the keyword is separated from the IF according to the delimiter, and finally the signature database is formed. The invention can greatly improve the classification efficiency while improving the classification accuracy.

Description

technical field

[0001] The invention relates to the technical field of information security, in particular to a method and device for classifying network traces based on keywords. Background technique

[0002] Classification of network traffic is the basis for ensuring cyberspace security. Traffic classification identifies different types of network protocol flows, which is of great significance for ensuring communication security, network management, network attack and defense, intrusion detection, and protocol reverse.

[0003] With the development of the Internet, the era of 5G Internet of Everything is about to usher in. Terminals such as computers, mobile phones, and sensors generate a large amount of traffic, and the classification management of a large amount of traffic poses challenges to the existing traffic classification schemes. Traffic classification is crucial to network management, such as monitoring network resources, discovering and handling network faults...
