Details

We are very excited to announce that the 12th Athenian Papers We Love meetup will feature George Kadianakis presenting on his work on Tor. This is a bit of a departure from our usual meetups since it won't focus on a single paper. Rather, the talk will cover various cutting-edge areas of research and engineering.

• George Kadianakis on Onions Everyday: Food? Medicine? Protocol?

Onions have many uses! Most people know Tor as a browser that provides a private web browsing experience. However, Tor can also provide privacy and anonymity to websites and other servers using "onion services". This talk is gonna give a high-level overview of how modern onion services work, shed some light to the crypto tricks used to make service-side anonymity happen and show people various improvements and behind-the-scenes developments that have happened in this space over the past year.
