Tor
An anonymizing overlay network for TCP
Tor is a free-software anonymizing network for web browsing, instant messaging, etc. Our deployed network has thousands of users. I'll talk about design decisions, some everyday uses for anonymity networks, and where we need to go from here.
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 50 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.
I'll give an overview of the Tor architecture, and talk about why you'd want to use it, what security it provides, and how user applications interface to it. I'll show a working Tor network, and invite the audience to connect to it and use it.
