KU Leuven spin-off creates world's first chip for encrypted data processing

Get your talk proposals in for FHE.org in Taipei next year...

The Call for Presentations for the 5th Annual FHE.org Conference on Fully Homomorphic Encryption, to be held in Taipei in March 2026 is open. Just under 7 weeks left (November 1st) to submit your 2-4 page PDF on your FHE project, use-case, or demo. #FHE #HomomorphicEncryption #FHEorg2026

Over 500 cryptographers warn the EU draft “Chat Control” could weaken end‑to‑end encryption. The EU council votes on the Danish text on Sep 12, 2025. https://getnews.me/eu-chat-control-criticized-by-500-cryptographers-over-privacy-risks/ #euchatcontrol #privacy #cryptography

The EU Parliament has published a new proposal for Chat Control to mass-surveil all digital communication in Europe. The proposal is ineffective, weakens secure communication, and violates basic human privacy. This must be stopped immediately. #ChatControl csa-scientist-open-letter.org/Sep2025

The EU wants to spend your money to assemble a giant mass surveillance machine with little effect on harm against children. Chat Control is not effective, weakens security for all and does not respect privacy. Contact your EU representatives and let them know. csa-scientist-open-letter.org/Sep2025

Check out the new open letter signed by more than 450 scientists who have serious concerns on the latest (July 2025) version of the chat control proposal. csa-scientist-open-letter.org/Sep2025

Officially old. @londmathsoc.bsky.social have sent me an email saying I qualify for senior membership. Down hill from here on in.

Just a flavour: 1) you can’t make a backdoor that only lets goodies in. Baddies will also use it, to devastating effect. 2) Security services, and even Europol- who face the shape end of global gangs and threats- have acknowledged as much.

Another great video from Oxford Maths dept...

Great video from Oxford Maths showing how Uni maths is different from school maths. Basically maths at Uni is a different subject to that at school. You really need to go back to basics to learn what a number is, and then build up from there.

Map of where people come from who submit papers to the IACR eprint archive eprint.iacr.org/geo/index.html Zooming way out what is interesting is that North America (185) is much less represented than Europe (406) and Asia (234). Note this is counting locations/institutes as opposed to papers.

Just a reminder to join us later today at 4PM CEST for FHE.org meetup with Alexandra Henzinger, graduate student at MIT presenting "Somewhat Homomorphic Encryption from Sparse LPN". RSVP at lu.ma/opf2g5sj #FHE #homomorphicencryption

Chatbots — LLMs — do not know facts and are not designed to be able to accurately answer factual questions. They are designed to find and mimic patterns of words, probabilistically. When they’re “right” it’s because correct things are often written down, so those patterns are frequent. That’s all.

British decline in one story. Any state which finds itself incapable of managing a project as basic as rolling out a 20th century tech between its biggest cities needs to ask itself some profound questions about what hope it has of managing the technologies of the 21st.

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

Fitting all (well, most) of COSIC into one picture? Not easy, but we did it! Curious about our research in #cryptography and #security? Check out our work: www.esat.kuleuven.be/cosic/ #choosecosic #COSIC #KULeuven

*Swipes right*

This is how you build secure systems: public source code, solid theoretical foundation, and third-party audits. Impressive. (Note: maybe we'll find flaws in this! And then they'll get fixed, thanks to transparency. That's also how secure systems work.) www.theguardian.com/gnm-press-of...

Wherein even the King doesn't meet the definition of "White British" enough for the Torygraph.

Excited to do more research on the real-world security of MPC with @proofnerd.bsky.social, thanks to this grant. We plan to hire some interns for this next summer. Congrats to all the other recipients so far, and to Zama for a smooth application process, ~1 month from announcement to notification!

Another great article from Lawrence Lundy-Bryan stateofthefuture.substack.com/p/dirty-work...

Eamonn and I received a Zama Cryptanalysis Grant to help with the lattice estimator github.com/malb/lattice.... We hope to hire interns to work on the estimator over two periods over the next 18 months. Zama are still taking applications for this grant, see here: www.zama.ai/post/announc...

Super pleased to see that Zama has just announced the first recipients of the Zama Cryptanalysis Grants. www.zama.ai/post/announc... The projects supported cover security of FHE, MPC, TEEs and ZK. The teams getting the grants represent some of the leading experts in their respective fields.

@cosic.bsky.social newsletter for April and May is now available... www.esat.kuleuven.be/cosic/sites/... New staff members, conferences talks, papers published, and a best paper award.

Super cool description of Diffie-Hellman

I made this diagram for a talk on encrypted messaging I recently gave, and I didn’t get to use it in the talk. I figured I’d share it here because I think it tells a story.

Thanks to our wonderful organization team and to the over 800 participants (including the affiliated events) that helped making Eurocrypt 2025 a success! And now I'll go to sleep for a year or two...

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

God the EU Commission is exhausting. Do these people seriously think they can demand a “lawful access” backdoor in US-hosted messaging apps, and that US intelligence *won’t* use that tool to relentlessly spy on EU interests? www.politico.eu/article/encr...
