[https://link.springer.com/article/10.1007/s11227-018-2268-y Real-time
identification of three Tor pluggable transports using machine learning
techniques]
> We report an empirical study on detection of three widely used Tor
pluggable transports, namely Obfs3, Obfs4, and ScrambleSuit using four
learning algorithms. We investigate the performance of Adaboost and Random
Forests as two ensemble methods. In addition, we study the effectiveness
of SVM and C4.5 as well-known parametric and nonparametric classifiers.
These algorithms use general statistics of first few packets of the
inspected flows. Experimental results conducted on real traffics show that
all the adopted algorithms can perfectly detect the desired traffics by
only inspecting first 10–50 packets. The trained classifiers can readily
be employed in modern network switches and intelligent traffic monitoring
systems.
