Happy to be publishing with Agathe Houzelot at the 20th edition of #FDTC which will occur tomorrow. Having published at the first and tenth editions, makes me feel old 😄 #fault #cryptography #fdtc2023

WhibOx is back for its 4th edition! This year, the focus is on ECDSA. Submit your implementations and accumulate 🍓s by August 8th to see if they can withstand scrutiny of 🍌s until the opening of CHES 2024. Most importantly, have fun! Learn more at whibox.io/contests/2024.

We are thrilled to announce that we won the WhibOx Contest Organizing Committee competition in the developer category and we finished in second place in the attacker category! It was an exciting CTF and we truly enjoyed competing against the other participants, especially BSI. #Whitebox #CHES2024

This week the Donjon brought its transportable laser bench to the jaif.io/2024 conference in Rennes by train 🚄. A proof that a functional Laser Fault Injection bench is not that impossible to see anywhere. Next step in the Village hardwear.io NL 2024 conference!

Nous avons également un nouveau poste d'évaluateur d'implémentations cryptographiques qui vient d'ouvrir sur Pessac à côté de Bordeaux !
