Roger Dingledine

Roger Dingledine is an American computer scientist known for his work on anonymous communication. He studied at MIT, where his master's thesis described the Free Haven anonymous storage project, and began working on onion routing with Paul Syverson of the Naval Research Laboratory in the early 2000s.

Tor

With Nick Mathewson and Syverson he wrote Tor: The Second-Generation Onion Router, presented at USENIX Security in 2004. The paper described a deployed, low-latency anonymity network with directory servers, circuit telescoping, and hidden services. In 2006 Dingledine and Mathewson founded The Tor Project as a non-profit to maintain the software.

Dingledine has spoken widely on censorship circumvention, including the design of bridges and pluggable transports to reach users behind national firewalls. He continues to work at The Tor Project as a director and researcher.
