Welcome

I'm David Llewellyn-Jones and this is my homepage. I'm a researcher in computer security who's also interested in programming and graphics. You might be interested in my research, my software or my random musings.

Want to know more about me? Here's a personality sketch written by a psychologist when I was in school.

“David is of high intelligence, although lacking in true creativity. He has a need for order and clarity, and for neat and tidy systems in which every detail finds its appropriate place. His writing is rather dull and mechanical, occasionally enlivened by somewhat corny puns and by flashes of imagination of the sci-fi type. He has a strong drive for competence. He seems to have little feel and little sympathy for other people and does not enjoy interacting with others. Self-centered, he nonetheless has a deep moral sense.”

Wow. Harsh. But disturbingly accurate.

22 Sep 2016 : ownNotes 1.8.6 for Sailfish OS #
A new version of ownNotes is now available. The main difference is a fix to allow it to work with more ownCloud installations (specifically, it now also works on installations where the domain root requires different credentials than the ownCloud subfolder). As before the source is on GitHub and the RPM on OpenRepos.

18 Jul 2016 : Regrexit Map #
I've added my Regrexit Map to the Web Apps page. It's just my quiet protest at the crazy and saddening referendum result. From a less emotive perspective, I've also posted up a blog entry about my experiences getting the site working with Amazon's CloudFront CDN.
26 Apr 2016 : Explicit Delegation using Configurable Cookies #
My slides from the 2016 Security Protocols Workshop are now available to download from the Presentations page. Ross Anderson wrote a brief but neat summary of the presentation on Light Blue Touchpaper, along with the other presentations from the workshop. This is my first publication working on the Pico project (I'll upload the paper once the post-presentation editing stage is complete).
