We will Make this deadline, very strongly, because we are WINNERS—but Europe and the Rest of the world will have to pay up BIGLY with the strongest and Most polished Best Paper awards! That is the least these low IQ individuals can do to Pay back what we Americans so richly deserve!

Other countries in Europe are LAUGHING at us, with their “Midnight Anywhere on Earth” conference submission Deadlines!! They’re finishing their papers and taking off for the Weekend at 2pm Friday, while we Americans have to pull ALL-NIGHTERS! Not on my (your favorite PC chair) watch—MAGTBAARHA!

The call for papers for PKC 2026 is out: pkc.iacr.org/2026/callfor...

Hot on the heels of this week's invited talk, I'm pleased to announce that we will soon be following up with a fantastic upcoming talk by the inimitable @kennyog.bsky.social!

The Isogeny Club Season 7 starts today! At 5pm CEST, Bruno Sterner will talk about finding large smooth twins from short lattice vectors. More details at isogeny.club

And so it ends where it all started (well, some 50km upstream of that first picture). Thanks for following and see you at the next #IsogenyCycle! #LID6

BREAKING: The U.K., Canada and Australia officially recognize a Palestinian state, a significant shift away from alignment with the U.S.

You never know when you'll make it #LID6 #IsogenyCycle

Alsace welcomed me with some of the most spectacular views! #LID6 #IsogenyCycle

Last leg of the trip. The sun is back and it's even too hot! Here's the Château de Lunéville this morning. Now finishing a siesta before crossing the Vosges. #LID6 #IsogenyCycle

The impact of Alfred Menezes in cryptography is profound. Francisco RH and I are organizing an afternoon session in Latincrypt to celebrate Alfred's career: menezesfest.info If you're coming to Medellín, consider attending!

Announcing The Isogeny Problems! A curated list of the seven foremost unsolved problems in isogeny-based cryptography. Solving one of these profound questions would mark a monumental advance, and as a resolver you'd get eternal honor and epic rewards! Full list: isogeni.es/problems

Found a bunch of researchers at the French border, they dragged me to Nancy 🇫🇷 #LID6 #IsogenyCycle

I have plenty of questions... #LID6 #IsogenyCycle

Thought for a moment of swapping the bike for a canoe, but I finally reached my first destination yesterday! Next chapter coming this weekend... #LID6 #IsogenyCycle

Weather's still crap this morning, so... #LID6 #IsogenyCycle

It's been that kind of day: drizzly morning, lead skies all day and the floodgates of heaven broke open just after I arrived in Luxembourg. All my pictures look dull when they're not just botched, so enjoy this half-decent view of the Mosel vineyards in Perl! #LID6 #IsogenyCycle

Guten Morgen von Gengenbach #LID6 #IsogenyCycle

That's where most of my conferences have been starting, lately. See you in Leuven! #LID6 #IsogenyCycle

Anyone who has been an IACR member in 2023-2026 should have received a link to respond to a survey about conferences and publishing. So far over 500 people have responded, but it will remain open for responses until Sept 12, 2025. I would also encourage people to use their forum invitations.

A horrifying statement published today by the Editorial Committee of the Agence France-Presse (AFP) news agency. "Without immediate intervention, the last reporters in Gaza will die" Translation from French to English by @cnorristrent.bsky.social:

Replication of Quantum Factorisation Records with an 8-bit Home Computer, an Abacus, and a Dog (Peter Gutmann, Stephan Neuhaus) ia.cr/2025/1237

Registration for the Leuven Isogeny Days 6 is now open! 📅 10–12 Sept 2025 @ KU Leuven Morning: research talks Afternoon: brainstorming sessions More info: www.esat.kuleuven.be/cosic/projec... #isogeny #isocrypt #erc #postquantum

We (finally) published all the material from this course on SQIsign, including lecture slides and exercise sheets for the Sage laboratory. Available here: github.com/andreavico/S...

AFRICACRYPT'25 accepted papers (africacrypt2025.sciencesconf.org/resource/page/…) & invited speakers (https://africacrypt2025.sciencesconf.org/resource/page/id/11) are online. Early registration deadline is May 30th (africacrypt2025.sciencesconf.org/resource/page/���). See you in Rabat 🇲🇦 in July! 😉

«[Nicușor Dan] part en 1992 en France poursuivre ses études à l’École normale supérieure de la rue d’Ulm. Il y obtient un DEA puis soutient en 1998 un doctorat en mathématiques à l’Université Paris XIII […] sous la direction de Christophe Soulé.» → Je me demande si je l'ai croisé, du coup. 🤔

Isogeny-based signatures have consistently had a breakthrough every two years! Let's see what 2026 will bring... (Well, except for SQIsignHD that came a year too late, but that's probably because of Covid)

Next week @lucianomaino.bsky.social and I will teach a week-long course on SQIsign at the University of Trento. The course will be both in-person and online: if you're interested, you can tune in Monday morning at 10:30 at unitn.zoom.us/j/88902079708 (details and full schedule in the image below)

Famous last words... There's still no power in most of Spain, diesel generators are buzzing on campus, we only have occasional access to the internet. We're having the best isogeny time of our lives here in Lleida, but none of it will be televised! See you tomorrow for the second day, hopefully!

The SQIparty starts on Monday, but it's still time to register! We prepared an exciting program for you with a balanced mix of talks, coding sprints, skillshares and other activities! www.cig.udl.cat/SQIparty2025... See you in Lleida!

The Isogeny Club - Brainstorm Days! - This event is a two-day affiliated event at Eurocrypt 2025, hosted in Madrid, Spain, and will take place on Saturday, May 3, and Sunday, May 4. Registration via the Eurocrypt 2025 registration process. isogeny.club/eurocrypt

Good news is that we're still accepting brainstorm topics!! If you have a brainstorm idea, send us a short description by email !

Season 6 of the Isogeny Club is officially done! You can catch up with all the talks here: isogeny.club If, like us, you haven't had enough isogenies for the term, be sure to join us at the Brainstorm Sessions affiliated with Eurocrypt: isogeny.club/eurocrypt

New work: we explain cubical arithmetic in simple terms to show you how easy it is to compute pairings. Essentially, you only need to know the Montgomery ladder! As a bonus, pairings from cubical arithmetic are faster than those from Miller's loop for applications in isogeny-based cryptography.

Deadline to submit to this conference is today!

Yes! RWC ❤️ Number Theory. Congrats to the CADO-NFS team!

Registration to the SQIparty is open, free, and we have a first sketch of a program! www.cig.udl.cat/SQIparty2025... Register and plan your travel quickly: the rooms are reserved only until Thursday! See you in Lleida!

Is this what it feels like to have a baby? (Defense is May 12th, be there or be square!)

Apply for SandboxAQ Scholarships! 10K USD for research, 5K USD for travel! Submission deadline is May 16th 2025! www.sandboxaq.com/scholarships

If you are visiting the United States, having a negative view of Trump is enough to get you denied entry. If this was coming out of Russia or China, we would deplore such an authoritarian attack on freedom of expression.

> claims no new results > adds in a tiny new result anyway > ??? anyway, enjoy the read!

Looking forward to speaking at this event. Come and enjoy an autumn day in Rome talking #cryptography.... www.decifris.it/fcir25

Registration for Eurocrypt 2025 is open!! Register at eurocrypt.iacr.org/2025/registr... Early bird registration deadline is 4th of April. Note that registration will be temporarily closed between the 29th and the 31st of March, and we'll have to cancel previous invoices left unpaid by March 30th.

Fancy some isogeny crypto? Join us for a 3-day workshop on isogeny-based cryptography in Lleida, Catalonia, April 28-30 www.cig.udl.cat/icrypto2025_... Brought to you by ULleida's Cryptography+Graphs group, the SQIsign team and friends! Registration and program coming soon Registration is free!

Second dumbest thing this morning: Trump bashing the CHiPs Act solely because it happened under Biden. CHIPS has wide bipartisan support and is designed to do what Trump thinks tariffs on China will. www.nytimes.com/2025/03/10/t...

What happens when two young, boutique wineries from #Austria host a pop-up #wine bar in #Paris for 28 days with 500 bottles of wine?
