Submission + - Inside the Great Firewall of China's Tor Blocking (

Trailrunner7 writes: The much-discussed Great Firewall of China is meant to prevent Chinese citizens from getting to Web sites and content that the country's government doesn't approve of, and it's been endowed with some near-mythical powers by observers over the years. But it's somewhat rare to get a look at the way that the system actually works in practice. Researchers at Team Cymru got just that recently when they were asked by the folks at the Tor Project to help investigate why a user in China was having his connections to a bridge relay outside of China terminated so quickly.

Not only is China able to identify Tor sessions, it can do so in near real-time and then probe the Tor bridge relay and then terminate the session within a couple of minutes.
