Intro

I am Head of Research at PQShield. Before that, I was an engineer at Thales. Still before it, I completed a PhD at the École Normale Supérieure. My main fields of interest are post-quantum cryptography and discrete algorithms, however I am open to most topics related to cryptography.

Before contacting me: Please note I no longer take journal reviews. I take few conference subreviews, but I accept invitations to conference program committees. I have poor facial memory, so apologies if we have met before and I don't recognise you.

Falcon

In 2016, NIST launched a standardization process to replace the current public-key cryptographic algorithms with post-quantum solutions. In July 2022, Falcon was selected as one of the three signature standards. Out of the three standards, Falcon is the one with the lowest communication cost (added sizes of a public key and a signature).

Falcon is a joint work with a team of talented cryptographers, cryptanalysts and implementers: Pierre-Alain Fouque, Jeffrey Hoffstein, Paul Kirchner, Vadim Lyubashevsky, Thomas Pornin, Thomas Ricosset, Gregor Seiler, William Whyte and Zhenfei Zhang.
