We are going to have 4 permanent positions at @Polytechnique this year (in a 4 year plan, leading up to 8 total 2 engineers) in Cybersecurity (both starting and prof level).
It could be the occasion to create a new team and or reinforce the existing ones (Crypto and Networks)

The Smoo.th CryptoLib is the Solidity library with the lowest gas cost for ECDSA verification on non-native Ethereum elliptic curves. We were pleased to audit this nice piece of work. Our audit report is available at github.com/get-smooth/crypto…

🌉 TCitH bridges MPC in the Head, VOLE in the Head and Ligero -type proof systems.
💍 One application: the shortest post-quantum ring signatures in the current state of the art.

Are you curious where cryptographers work around the world? Here is a plot of the affiliations that people have listed in eprint: eprint.iacr.org/geo/index.ht… I'm guessing that Russia is under-represented in this data set.

The WhibOx contest is back in 2024! 🍓⚔️🍌
As usual white-box designers (🍓) and white-box attackers (🍌) will fight a relentless battle.
The battlefield will be AES (as in 2017 and 2019) or ECDSA (as in 2021). Which one should it be?
Please vote!
