Excited for our new paper on distributed proof generation of FRI-based SNARKs! We believe this is the first horizontally scalable SNARK for general circuits that is both transparent and plausibly post-quantum (PQ) secure.

A: "We have too many meetings. We can't get anything done." B: "You are right. Let's discuss this tomorrow. Does 10am work for you? " A: 😐

Double-blind peer review is such a bullshit process in the cryptography community. Papers are all on eprint.

Our work on multi-message multi-recipient public key encryption is out! We build on Kyber (ML-KEM) and get great efficiency. Kudos to Hongxiao Wang for leading this work!

Matt Blaze's recent Congressional testimony on the prodigious attack surface of modern telecoms, and the role of end-to-end encryption in mitigating creaky infrastructure is REQUIRED READING oversight.house.gov/wp-content/u...

FHE.org have a great virtual MeetUp tomorrow with one of the OG's of lattice based crypto: Daniele Micciancio. He will talk about "Bit Security: Optimal Adversaries, Equivalence Results, and a Toolbox for Computational-statistical Security Analysis" lu.ma/sahiap4q?tk=... #cryptography

Emad Heydari Beni from COSIC presented "Emad Heydari BeniQRYPT: End-to-End Encrypted Audio Calls via Blind Audio Mixing" at RWC 2025 in Sofia last week. Here's a nice picture of (ex)cosix at #rwc2025. rwc.iacr.org/2025/program...

After a week of ZK, FHE, audio mixing and applied crypto, it's good to be back home and play with my little girls.

Embrace for impact!! #RealWorldCrypto

Paper submitted to ePrint

The GSMA RCS E2EE spec using MLS is only 90 pages! light reading 😁 www.gsma.com/solutions-an...

Robin Geelen presents GBFV at FHE.org. GBFV is a SNARK friendly FHE scheme that supports the Goldilocks prime. We use it in our Blind zkSNARKs.

Me presenting about The Fellowship of the Galois Rings at Real World Multi-Party Computation in Sofia

At #RealWorldCrypto2025, we plan to present how we do end-to-end encrypted audio calls. Things we build at Nokia Bell Labs.

Now Jannik is presenting our paper at @zkproof.org @cosic.bsky.social

For some ZK folks, ZKProof is the event and RWC the side event. Learning new perspectives!

The list of accepted talk at @rwc.iacr.org is now available: rwc.iacr.org/2025/accepte... Early registration ends 26 February. CC: programme co-chair @nicksullivan.org

Things have been relatively quiet on the “crypto wars” front, which makes me think we’re going to see something dramatic soon. Maybe not here in the US, but probably from another US-allied country.

The amount of ZKP cryptography being designed and deployed in the last few years is exciting and at the same time terrifying. These protocols are currently supposed to secure our financial infrastructure.

68 (UK affiliated) researchers working on security and privacy have raised alarms about provisions in the UK #OnlineSafetyBill: "our concern is that surveillance technologies are deployed in the spirit of providing online safety." Read our letter here: https://haddadi.github.io/UKOSBOpenletter.pdf

Have a FAEST on post-quantum digital signatures based on the security of the AES function... https://faest.info/ Great work from a team of Aalto, Aarhus, AIT, Bocconi, DTU, KU Leuven, and TU Graz authors.
