Is it possible to write a serious, non-bullshit, paper mentioning crypto, quantum, *and* AI ? We answer this question positively in a joint work with Wessel van Woerden Marc Stevens, solving Darmstadt lattice challenge SVP-180 using AI-purpose hardware.eprint.iacr.org/2021/141.pdf

#ePrint Comparing Lattice Families for Bounded Distance Decoding near Minkowski's Bound.: O Lapiha ia.cr/2021/1052

Update from Léo Ducas @[email protected] and Wessel van Woerden: the special lattice problem considered in the new work can be solved easily and classically (no quantum) using standard tools LLL+Babai. So, no quantum advantage has been shown, nor anything new classically. github.com/lducas/BDD-note

🆕📣Today at #ASIACRYPT21 the paper "NTRU Fatigue: How Stretched is Overstretched?" is presented by Wessel van Woerden. Co-author is Léo Ducas @[email protected] from PROMETHEUS consortium at CWI The presentation is available at: youtube.com/watch?v=Uzw87j…

Registration for the summer school in post-quantum cryptography is open!

The COSIC seminar by Wessel van Woerden (CWI, Amsterdam) on "On the Lattice Isomorphism Problem, Quadratic Forms, Remarkable Lattices, and Cryptography" can now be watched on our YouTube channel: youtube.com/watch?v=QlCSgB…

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…

Announcing the lattice-based cryptography club! Do you want to learn this type of cryptography? Find resources here: thelatticeclub.com Beautifully curated by Octavio Pérez Kempner and me. Thank you Tancrède Lepoint Muhammed Esgin Cecilia Boschini and more for allowing us to put your amazing thesis there!

#ePrint Hawk: Module LIP makes Lattice Signatures Fast, Compact and Simple: L Ducas, EW Postlethwaite, LN Pulles, W van Woerden ia.cr/2022/1155

HAWK : It's kind of like FALCON, but without the Floating-Point hassle. And it signs 5 to 30 time faster. Co-designed with Eamonn Postlethwaite, Ludo Pulles & Wessel van Woerden

Two weeks ago, Koen brilliantly defended his PhD Thesis, offering us fantastic illustrations, and a very approachable introduction to rather non-trivial mathematical objects. A must read to learn about ideal lattices ! …rlypublications.universiteitleiden.nl/access/item%3A… koendeboer.com

It turns out that the task of breaking a cryptographic system can, in some cases, be recast as another problem: finding a relatively short vector in a lattice. A new approach helps researchers do this more efficiently. Maddie Goldberg reports: quantamagazine.org/celebrated-cry…

We are organizing a Spring school on post-quantum cryptography in Porto, March 11-15, 2024. We assembled a great set of speakers covering all areas of post-quantum cryptography. Mark the date, registration will open early 2024. pqc-spring-school.nl

It was a great pleasure to get together and share ideas between two wonderful communities last week at our attacc-workshop on lattice- and code-based cryptanalysis, co-organized with Felicitas Hörmann at DLR - English😀 Thanks for joining us! dlr.de/kn/attacc

Happy to announce an exciting conference in Budapest (5th-9th August) called "Mathematics for post-quantum cryptanalysis" (esat.kuleuven.be/cosic/events/m…) jointly organized with Wouter Castryck and Fre Vercauteren. 1/2
