Hey! I'm David, cofounder of zkSecurity and the author of the Real-World Cryptography book. I was previously a crypto architect at O(1) Labs (working on the Mina cryptocurrency), before that I was the security lead for Diem (formerly Libra) at Novi (Facebook), and a security consultant for the Cryptography Services of NCC Group. This is my blog about cryptography and security and other related topics that I find interesting.

Permutation-Based Crypto 2023 posted January 2023

I'm pleased to announce that I'm part of the steering committee of the Permutation-Based Crypto 2023 one-day workshop which will take place in Lyon, France (my hometown) colocated with Eurocrypt.

Things have changed a lot since the previous one took place (pre-covid!) so I expect some new developments to join the party (wink wink SNARK-friendly sponges).

If you're interested in presenting some research, check the call for contributions!

Well done! You've reached the end of my post. Now you can leave a comment or read something else.
