Skype使用强大的加密来保护整个Skype网络内部的通信。客户端随机选择通信端口。因此，传统的基于端口或基于有效载荷的Skype流量识别是不可行的。在本文中，我们介绍了一种新的基于流动力学的识别方法来发现Skype主机和语音呼叫。我们的方法只使用包头和提取的流级信息。整个识别过程在Transact-SQL中编写了脚本，因此可以自动执行。我们还提出了算法的验证与一些识别结果的分析。
Skype uses strong encryption to secure communications inside the whole Skype network. Clients choose communication ports randomly. Therefore traditional port based or payload based identification of Skype traffic is not feasible. In this paper we introduce a novel flow dynamics based identification method to discover Skype host and voice calls as well. Our method uses only packet headers and the extracted flow level information. The whole identification process is scripted in Transact-SQL, thus it can be executed automatically. We also present the validation of the algorithm together with some analysis of the identification results.
