Academic I study security protocols, particularly definitions and formal analysis (in the sense of formal mathematics, not that of formal methods). I'm interested in Certificate Transparency, TextSecure/Axolotl, TLS 1.3, the TAMARIN prover, WebRTC, and other such things. I'm an Oxford Cyber Security CDT student, supervised by Cas Cremers.newLuke, Cas and I recently published the paper On Post-Compromise Security.
Internet You can find me on many other websites. I 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, and LinkedIn. I listen to music through Spotify and motivate myself with Beeminder. FollowUpThen snoozes my emails, forecast.io handles weather, and Splitwise organises bills.
