katriel cohn-gordon

I'm an applied cryptographer interested in protocol design and analysis, particularly secure messaging. I tweet as @katrielalex. I'm an aspiring feminist, trying to be a better ally, and my pronoun.is/he.

Research   [publications, PhD thesis] My research interests include Signal, TLS 1.3, Certificate and Key Transparency, the Tamarin prover, and WebRTC. My Erdős number is four (one, two, three, four) if you allow conference publications, and infinite otherwise. I guest-reviewed for Black Hat USA and EU this year.

newOur ART paper was accepted to CCS 2018! ART is the starting point for the IETF MLS working group, looking at improving secure messaging. Hooray! As always, some Totally Accurate Register Coverage.

Code   I've been writing code for a while now, including at GSA Capital, Facebook, Google, Red Gate and Cantab Capital. I'm most at home writing data pipelines and scripting, but have turned my hand to all sorts (except assembly. I hate writing assembly).

Misc   You can find me on many other websites. I rarely post long-form and short-form things, and used to spend a lot of time on Stack Overflow but these days it's Github if anything. The usual collection of profiles are where you'd expect them on Facebook, MetaFilter, Twitter and LinkedIn. I listen to music through Spotify and motivate myself with Beeminder. FollowUpThen snoozes my emails, darksky handles weather, and Splitwise organises bills.
