Overview of clustering analysis algorithms in unknown protocol recognition

Abstract

In the process of identifying unknown protocol of bit stream, the clustering of data sets of bit stream in the protocol is the basis of further identifying unknown protocol. Therefore, on the one hand, this paper analyses the classical clustering algorithms used in unknown protocol recognition from three perspectives: the whole process of clustering analysis, similarity measurement and clustering result evaluation. On the other hand, the development trend of clustering algorithm in unknown protocol recognition is summarized, and other problems in unknown protocol recognition can be solved by clustering algorithm according to the characteristics of bit stream data set, which can provide reference for future research work. Finally, the challenges faced by the Research Institute and the prospects for future work are given.
