Have a look into the arms race between the Tor project and the Great Firewall of China.
- yoran 9y agoRelated to this, this an interesting paper that clarifies how the Great Firewall discovers Tor nodes by doing active probing: https://nymity.ch/active-probing/imc2015.pdf https://nymity.ch/active-probing/imc2015.pdf. No deep packet inspection is necessary when you pretend to be a Tor user and can identify the typical response for a Tor node.
- swiley 9y agoPerhaps this could be defended against by probabilistic connection rejection?
- ethbro 9y agoFor anyone in on this, would be absolutely fascinated by any good, recent(ish) links where this is documented or discussed. And hats off to the Tor people and all the good work they're doing there.
