Classifying service flows in the encrypted skype traffic
Maciej Korczyński, Andrzej Duda · 2012
In this paper, we consider the problem of detecting Skype traffic and classifying Skype service flows such as voice calls, skypeOut, video conferencing, chat, file upload and download. We propose a classification method for Skype encrypted traffic based on the Statistical Protocol IDentification (SPID) that analyzes statistical values of some traffic attributes. We have evaluated our method on a representative dataset to show excellent performance in terms of Precision and Recall.
