Anonymity loves Diversity: The Case of Tor

Lecture by Alexander Færøy, and Georg Koppen at FOSS North in Cyberspace on November 1, 2020.

Tor is an anonymity network consisting of relays run by thousands of volunteers around the world aiming at giving back privacy on the Internet. The network carries around 200 Gbit/s of traffic and helps somewhere between 2,000,000 and 8,000,000 users every day.

In this talk, we will explain why diversity is essential for reaching the desired security and anonymity properties. Both for the Tor Project organization itself, but also for our community, as well as in our daily work with creating privacy-enhancing tools such as the Tor Browser or safeguarding the network itself against attackers.
