Submission + - China blocks VPN connections using machine learning algorithms?

An anonymous reader writes: The internet control in China seems to have been tightened recently, according to the Guardian []. Several VPN providers claimed that the censorship system can "learn, discover and block" encrypted VPN protocols.

Using machine learning algorithms in protocol classification is not exactly a new topic in the field []. And given the fact that even the founding father of the "Great Firewall", Fan Bingxing [] himself has also written a paper about utilizing machine learning algorithm in encrypted traffic analysis [], it would be not suprising at all, if they are now starting to identify suspicious encrypted traffic using numerically efficient classifiers. []

So the arm race between anti-censorship and surveillance technology goes on .
