More about me

I'm also an advisor at Archetype. I was previously a cryptography architect of Mina at O(1) Labs, the security lead for Libra/Diem at Facebook, and a security engineer at the Cryptography Services of NCC Group. Welcome to my blog about cryptography, security, and other related topics.

“Cryptologie” is the French spelling of “cryptology.”

    Permutation-Based Crypto 2023

    blog

    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!
