I have some personal news 👀 Today is my last day at Google! 🛫🏝🌅 I am leaving to take a long break from full-time employment and explore different ways Open Source maintainers can get paid. I want to make words.filippo.io/professional-m… a thing, starting with Go cryptography!

We found a way to mount *remote timing* attacks on *constant-time* cryptographic code running on modern x86 processors. How is that possible? With #hertzbleed! Here is how it works (with yingchen wang). hertzbleed.com

As we prepare for the possible assault of a future quantum computer, NIST has chosen the first group of tools for our post-quantum cryptographic standard: 🔒 CRYSTALS-Kyber 🔒 CRYSTALS-Dilithium 🔒 FALCON 🔒 Sphincs+ Learn more: nist.gov/news-events/ne…

#ePrint An efficient key recovery attack on SIDH (preliminary version): W Castryck, T Decru ia.cr/2022/975

In this preprint, in order to counter the Castryck-Decru attack (and derivatives), we suggest to use a fixed degree, but then mask only the torsion point information. How do we do that and why is this worth exploring? A thread! 1/n

Officially, now the announcement is out! Calling for new signature algorithms for the NIST PQC standardisation effort.

In this year’s magistrale, different awards were given ✨ First for professors: 🏅 Award for excellence in computer science education : Prof. Rachid Guerraoui 🏅 IC Faculty Polysphere : Prof. Emre Telatar

Finally, some students were awarded special prizes: 🏅 Commune de Chavannes-près-Renens price for an outstanding student: Tom Demont 🏅Kudelski price for a significant project in cybersecurity: Guilhem Niot (IN)

We are very proud to announce that our colleague, Guilhem Niot, has been awarded the prestigious Kudelski Award from the École Polytechnique Fédérale de Lausanne @epfl_en) for his outstanding Master's thesis project he conducted at PQShield. hubs.li/Q02Sv-bp0

Very excited to share our first exploration of threshold MAYO (yes, the PQC algorithm)! 🎉 Joint work with the amazing Daniel Escudero and Guilhem N. The ideas extend to UOV as well—let’s have MV-based threshold cryptography! 📄 eprint.iacr.org/2024/1960.pdf

'Share the MAYO' (with Daniel Escudero and Guilhem N) about thresholdising MAYO and UOV goes to Taiwan at PQCrypto2025! eprint.iacr.org/2024/1960

Our previous microgrants have gone to: * 2025, D. Carnemolla: On the unbiasability of existing Verifiable Random Functions * 2025, G. Niot, R. del Pino: Distributing the Dilithium digital signature * 2025, C. Ganesh, B. Kanukurthi: Cryptographic Protocols for Rational Parties

Our Cryptography Researcher Guilhem Niot will be speaking at the Crypto Day, Telecom Paris on the 18th September 2026. Guilhem will be speaking on - "PQC + Threshold: State of the Art in Threshold Quantum-Resistant Signatures". We hope to see you too in Paris!
