Tor (second-generation Onion Routing) is a distributed overlay network that anonymizes TCP-based applications like web browsing, secure shell, and instant messaging. We have a deployed network of 30 nodes in the US and Europe, and the code is released unencumbered as free software. Tor's rendezvous point design enables location-hidden services—users can run a standard webserver or other service without revealing its IP.

Roger Dingledine is a security and privacy researcher. While at MIT he developed Free Haven, one of the early peer-to-peer systems that emphasized resource management while retaining anonymity for its users. Currently he consults for the US Navy to design and develop systems for anonymity and traffic analysis resistance. Recent work includes anonymous publishing and communication systems, traffic analysis resistance, censorship resistance, attack resistance for decentralized networks, and reputation.
