Abstract: In this course, I will give a basic overview of onion routing, Tor, and onion services—popular means to improving the security and privacy of sites and the users accessing them. I will discuss motivational examples, basic design, and models of adversaries and trust. I will also describe onion services, which are accessible via Tor Browser, and how to extend their self-authenticating features to traditional addresses accessible from ordinary browsers via ordinary internet routing. Lastly I will describe how these self-authenticating traditional addresses offer improvements over both existing systems for usable onion services and the web’s certificate revocation infrastructure.
