A presentation on Tor software was scheduled to be held at the Black Hat security conference next month. The talk was canceled at the request of the legal counsel of the university’s Software Engineering Institute. Tor project leader Roger Dingledine says the issue affects Tor relays, the Tor network nodes that route user connections in a way that’s meant to hide the traffic’s origin and destination from potential network eavesdroppers. The software allows users to access resources on the Internet without revealing their real IP (Internet Protocol) addresses.”]
