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

[Christophe Giraud @Kristophe24]

Hello à tous! Un poste vient de s'ouvrir au sein de notre Cryptography & Security Lab pour un développeur en crypto embarquée (3 à 5 ans d’expérience) sur La Défense.

[Christophe Giraud @Kristophe24]

Côté algo, on couvre large, du 3DES (oui, encore lui 😄) jusqu’au ML-KEM.

20 % du temps sera dédié à la recherche avancée (publications, brevets, etc).

Si tu veux bosser sur des technos de pointe dans une super équipe, contacte moi en DM!

Hello à tous! Un poste vient de s'ouvrir au sein de notre Cryptography & Security Lab pour un développeur en crypto embarquée (3 à 5 ans d’expérience) sur La Défense.

[Christophe Giraud @Kristophe24]

La mission principale sera de contribuer au développement de nos librairies cryptographiques sécurisées contre les attaques embarquées (side-channel, injection de faute…), tout en gardant un haut niveau de performance.

This week the Donjon brought its transportable laser bench to the https://t.co/xrCRQEAv2a 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!

@NinjaLabFr That's bloody nice! Well done Thomas 👍

[Christophe Giraud @Kristophe24]

We are thrilled to announce that we won the @WhiboxC 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_Bund. #Whitebox #CHES2024

We are very excited to share our last research work: 𝐄𝐔𝐂𝐋𝐄𝐀𝐊, authored by Thomas Roche.

An electromagnetic Side-Channel Vulnerability in the ECDSA implementation of all Infineon security microcontrollers, notably impacting all YubiKey 5 Series.

Quantum computers could imperil the security of confidential electronic information, such as emails. To counter this threat, NIST has finalized its set of three encryption algorithms designed to withstand a future quantum computer’s cyberattacks: https://t.co/WYNO9j7Owz
