✨ It’s been two months since Mélissa Rossi joined CryptoExperts as a Cryptography Expert, and we’re thrilled to have her on board! 🔐 Her expertise in post-quantum cryptography strengthens our team, and we look forward to achieving great things together. 🚀
These candidates -MQOM, SDitH, Mirath, and RYDE- are among the 14 chosen for this next phase. Each leverages the MPC-in-the-Head paradigm applied to a different problem and is further enhanced by recent advancements in the field. Stay tuned for our upcoming submission updates!
We're excited to share that NIST has selected the four post-quantum signature candidates co-submitted by CryptoExperts to advance to Round 2 in their call for additional post-quantum signatures.
🚀 Great news!
We’re thrilled to welcome Gaëtan to the CryptoExperts team as a post-doc researcher! 🎉 His expertise will be a valuable asset for our work on the ERC project AMAskZONE. Looking forward to groundbreaking collaboration ahead! #ERCStG
🎓 A warm welcome to Auguste, who joins us as a PhD student at CryptoExperts! After completing his internship with us, Auguste will be working on post-quantum cryptographic techniques for verifiable computation. Great to have you back, Auguste! 🚀
🎓 We’re excited to welcome Victor, our new PhD student at CryptoExperts! After completing an internship with us on the same topic, he is now continuing his work on the generation of masking countermeasures against side-channel attacks. Welcome back, Victor! 🚀
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…

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?

(5/6) The performances are not as good as for schemes based on structured lattice problems (such as Dilithium or Falcon) but they are better than hash-based signatures (such as SPHINCS+). These schemes can hence be considered as conservative alternatives to lattice-based schemes.
(4/6) These 4 schemes apply the MPCitH paradigm to different hard problems from coding theory and multivariate cryptography. These problems are unstructured which make them particularly conservative in terms of security.
(3/6) These signature schemes are based on the MPC in the Head (MPCitH) paradigm which turns an MPC protocol into a zero-knowledge proof, the latter being then turned into a signature scheme thanks to the standard Fiat-Shamir transform.
🧵 (1/6) We are pleased to share that our teammates @tfeneuil and @mrivain with further collaborators from academia and industry have co-designed 4 submissions to the NIST call for additional post-quantum signatures (csrc.nist.gov/projects/pqc-d…), selected for Round 1: ...
