Denmark is best in EU in getting workers back into jobs (twice the average rate). They also do tons of RCTs to find out what works and apply behavior science. Can’t say it’s causal, but it’s an interesting correlation at least.

The 7th workshop on Privacy Preserving Machine Learning will take place on August 17, 2025 (Sunday), as an affiliated event of the 45th CRYPTO 2025 conference.

Ahem.

Save the date! The next NordiCrypt will take place on Monday June 30th in Aarhus. We will start around 10:00. More details soon at sites.google.com/view/nordicr...

Oh wow, this is really great work. Recent results on PCGs allowed much more efficient MPC preprocessing (among other things) using somewhat new assumptions. Apparently, these assumptions are too strong. Congratulations to the authors on their IACR grant slam of breaks :)

This is cool heimberger.xyz/oprfs.html

Never thought I'd participate in making a whole scientific conference dance the Macarena. Yet here we are.

Oops :)

Our paper on attacking concurrent MPC implementations is finally on eprint 🎉 (And @schollster.bsky.social will present it at S&P 2025!) A summary 🧵

It takes a certain academic age and amount of accomplishments that allows you to use Comic Sans AND get away with it.

Don't forget to submit your most hilarious talk, musical performance, general announcement or recent result to the Eurocrypt 2025 Rump Session!

Next week I'll be at IACR Eurocrypt in Madrid. Let's have a chat if you're also around!

ZK deployed in get another use case. Yay!

"To help foster a safer, more secure environment for everyone, we will also open source our ZKP technology to other wallets and online services."

Given the behavior of the current US administration, it will be very hard to tell truth from joke news this April 1st.

Sure. Great idea. Planning conferences in the US. So, who despite US Americans and Russians do you think will go at this point?

I guess we need to update our security games?

The Trump admin communicates on Signal and added a journalist to a war planning chat group. Despite the obvious trainwreck that this news is (but not surprising), I'd like to thank them all for some extra material I'll teach tomorrow in a course about private communication :)

Update on crypto.iacr.org/2025/

Today's Nordicrypt is going poetic :)

Martin and Kenny are organizing a meeting to discuss the impact of recent political events on both our research and our community. If you're at Eurocrypt this year, consider attending!

There has been a lot of chatter today about Zelenskyy's meeting with Trump, some regarding this moment when White House correspondent Brian Glenn asked if the Ukrainian president plans to wear a suit. I want to address idea in this thread. 🧵

I'm happy to share some updates on the FAEST round 2 digital signature algorithm: - we have achieved substantially smaller signatures - at the same time, the new sign/verify algorithms achieve more competitive performance

Don't forget to sign up for the next NordiCrypt on March 21st at ITU in Copenhagen, and submit your exciting recent research results as a talk! More info on sites.google.com/view/nordicr... See you there!

Great news from the cryptography team at DTU Compute: we managed to get 4 paper accepted at this year's IACR Eurocrypt conference. I'm very happy to see how our footprint in the research community grows :)

I thought cryptocurrency was supposed to be a hedge against inflation and weird government screwups.

I just want to tell every researcher in the US: if you want to get out of this misery, come to Europe. Plenty of research funding, good universities, you have rights under labor laws and most countries don't have sh*theads running the show.

If you’re part of a major company that’s advising your employees to use Signal after this Salt Typhoon thing, consider donating to Signal Foundation.

With the year almost finished, I'm on my way to the last big professional event for me: I've been invited by the cryptography research group at NTT Japan to give a lecture series on (V)OLE and it's use cases. Looking forward to spread the word about FAEST, Mac'n'Cheese and all the good stuff :)

Ever wondered how to implement loops in MPC? My latest paper has an answer: it's all about finding the right balance.
