Very excited about the International Workshop on Foundations and Applications of Privacy-Enhancing Cryptography (PrivCrypt) that I am co-organizing with @drl3c7er.bsky.social and Lucjan Hanzlik as an affiliated event to IACR Eurocrypt in Rome this Sunday: privcryptworkshop.github.io/program.html

There are no technical or compliance reasons to double the size of symmetric keys in response to the threat of quantum computers. This common misunderstanding of Grover's algorithm risks wasting limited resources that should go towards deploying actually urgent post-quantum algorithms.

Objects in the quantum mirror are closer than they appear. https://blog.google/innovation-and-ai/technology/safety-security/cryptography-migration-timeline/

Two papers came out last week that suggest classical asymmetric cryptography might indeed be broken by quantum computers in just a few years. That means we need to ship post-quantum crypto now, with the tools we have: ML-KEM and ML-DSA. I didn't think PQ auth was so urgent until recently.

Overdue quantum landscape update: sam-jaques.appspot.com/quantum_land... A 2d chart can only say so much. tl;dr new results are still overhyped, but definitely worth taking seriously. This chart is based on surface codes and a big question now is whether new codes can be practical (=>useless chart)

The EU seems to be going in the right direction when it comes to mass message scanning. Unfortunately, the fact that this vote was necessary proves that we’re still in the dark timeline. cyberinsider.com/eu-votes-to-...

Governments worldwide turn to age-based access control to Internet services to protect children. More than 370 scientists call for a moratorium until there is a good understanding of their feasibility, effectiveness, and societal impact: csa-scientist-open-letter.org/ageverif-Feb...

Har vært på leting etter snill, trygg og ikke-amerikansk telefon. Jeg fant ut to ting: 1) At det er umulig å komme helt i mål, og hvorfor 2) Hvorfor det likevel er verdt å forsøke Håper du vil lese! Artikkelen er også blitt en slags podkast i lydutgaven, et eksperiment, om du heller vil lytte

Published an opinion piece (in Norwegian) about PQC (yay) vs QKD (buu) in @digi.no today, together with @jonathan.isogeny.club, Kristian Gjøsteen (NTNU), Øyvind Ytrehus (UiB), and Morten Øygarden (UiB): www.digi.no/artikler/deb...

I am very happy to announce that thanks to the hard work of many people (The "MIKE Team"), we now have a working implementation in SageMath of MIKE (Module Isogeny Key Exchange).

A team of computer scientists from the Applied Cryptography Group, including Matteo Scarlata, Professor Kenny Paterson, Giovanni Torrisi and Matilda Backendal, have discovered serious security vulnerabilities in three popular cloud-based password managers. Read more ⬇️

Germany has agreed to stop ChatControl for now, due to huge amounts of public pressure. Good job! The bad news is that it could come back as soon as December, and the German government has interpreted the feedback as a need to “moderate” the proposal.

Discord user IDs getting leaked is the entirely predictable consequence of requiring platforms to do age verification. That data never goes away, it spreads. In this case, into appeals in a breached customer support database. And predictably, it can get worse. www.404media.co/the-discord-...

Someone please make me understand how Denmark can be at the same time freaking out about hybrid war with Russia AND pushing for government-mandated spyware as Chat Control.

What is chat control? Good video explainer developed by @carmelatroncoso.bsky.social and team at Max Planck Institute for Security and Privacy #chatcontrol www.youtube.com/watch?v=-y2O...

We are alarmed by reports that Germany is on the verge of a catastrophic about-face, reversing its longstanding and principled opposition to the EU’s Chat Control proposal which, if passed, could spell the end of the right to privacy in Europe. signal.org/blog/pdfs/ge...

In 2023, Signal was the first mainstream messenger to enable post-quantum cryptography. We’re still ahead of the (elliptical) curve, implementing a new hybrid PQ ratchet ensuring Forward Secrecy & Post-Compromise Security even in a post-quantum world. signal.org/blog/spqr/

More than 500 researchers have signed an open letter against the dangerous EU proposal on chat control. The proposal remains ineffective, undoes decades of results in E2E encryption, and threatens the privacy of half a billion citizens. csa-scientist-open-letter.org/Sep2025

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

EU is demanding that every site use age verification technology, while insisting it do things it cannot do, and behave in a manner it cannot behave. This is not policy making. This is wishful thinking, with a side of "we'll just blame the tech companies for not waving their magic wand."

We've published Volume 2, Issue 2 of IACR Communications in Cryptology. This now brings us over 200 articles published in six issues. cic.iacr.org/i/2/2 It may be time to overhaul the rest of IACR publishing. 🤔

This battle will keep playing out over and over again until they achieve something that their own citizens have made it clear they don’t want. www.techradar.com/vpn/vpn-priv...

Well, this horrible idea refuses to die so we should refuse to let it pass and start organizing again. ec.europa.eu/commission/p...

An out-of-schedule update to my quantum landscape chart: sam-jaques.appspot.com/quantum_land..., prompted by @craiggidney.bsky.social 's new paper: arxiv.org/abs/2505.15917. A startling jump (20x) in how easy quantum factoring can be! Also: much improved web design!

The problem with most machine-based random number generators is that they’re not TRULY random, so if you need genuine randomness it is sometimes necessary to link your code to an external random process like a physical noise source or the current rate of US tariffs on a given country.
