Abstract : 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.
