|---|---|---|
To protect user privacy (e.g., IP address and sensitive data in a packet), many traffic protection methods, like traffic obfuscation and encryption technologies, are introduced. However, these methods have been used by attackers to transmit malicious traffic, posing a serious threat to network security. To enhance network traffic supervision, this paper proposes a new traffic classification model based on Gaussian mixture models and hidden Markov models, named MGHMM. To evaluate the effectiveness of the proposed model, we first classify protocols and identify the obfuscated traffic by experiments. Then, we compare the classification performance of MGHMM with that of the latest Vector Quantiser-based traffic classification algorithm. On the basis of the experiment, the relation between the classification and the number of hidden Markov states, and the number of mixture of Gaussian distributions required to describe the hidden states, are analyzed. |
