There are speakers from Nokia, Bosch, Cybernetica, Roseman Labs, Lattica AI, ST Microelectronics (and me)

Logic and trust: Constructive reasoning | Cybernetica Explore how constructive logic and formal reasoning build trust in security systems. Learn the difference from classical logic and why context matters for trust.

Cybersecurity protip from Digital Tech Summit in Copenhagen.

We are looking for a cybersecurity professor to strengthen Estonia's existing expertise. We are looking for an ambitious researcher (with a steady presence at big four security conferences) with demonstrated leadership skills who can build a larger team. iacr.org/jobs/item/4075

Travelling to Copenhagen this week to constructively rain on peoples' AI parades at the Digital Tech Summit.

Constructively, I promise. Can't have economic weakness in Europe this time around, or you know, ever.

At least in Estonia, the story of "digital signatures and Smart-ID could be broken by a quantum computer" still raises eyebrows.

If I get cryptographic agility in systems *and* get rid of MD5, I would totally have no cryptographically relevant quantum computer ever. May it do computational chemistry and cold fusion for all I care.

Might be it won't do that either.

Getting rid of MD5 is still a trip to Awesome Town.

So about that Quantum Lattice Thing: Rebuttal to "Exact Coset Sampling for Quantum Lattice Algorithms" In this note we identify major issues with “Exact Coset Sampling for Quantum Lattice Algorithms” by Zhang. The issues include: • in the first version, the proposed algorithm requires foreknowledge of...

Looks like cryptographers can still safely fall asleep again....

Lattice crypto is still a go for the post-quantum transition.

Picard technology tip: Sometimes your chief engineer can build new systems that are better than your existing enterprise software.

Yesterday, news broke that Dominion Voting Systems was sold to a new company, Liberty Vote. Dominion, the second-largest voting systems vendor in the US that currently tabulates 1 in 5 American votes, is no more.

The Discord Hack is Every User’s Worst Nightmare A hack impacting Discord’s age verification process shows in stark terms the risk of tech companies collecting users’ ID documents. Now the hackers are posting peoples’ IDs and other sensitive informa...

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-...

The next COED Industry Day is going to be held in Milan....

Going to be a super cool mix of speakers, from Bosch, Nokia Bell Labs, Cybernetica, Roseman Labs and Zama

My colleagues from Cybernetica and I decided to make another variant of Smart-ID / SplitKey protocol. Coppercloud is a two-party blind RSA signing with private key being split between a user and a server.
Perfect for the future of privacy-preserving digital wallets! 🌐✨

Jokes aside, this really is a risk analysis maturity thing. Right now, looking around in the world, it is rather easy to see how infrastructure, once built, will be repurposed.

You had a typo in there, meaning to write "idealistic" or "naive"?

Hypothesis: their risk model does not look look ahead more than a few years.

A lot of generally principled people have been riding the “I do this because I believe in the mission of stopping bad guys” and I think those principles are going to be tested soon.

Our privacy/ML/EXAI team would love to be on board with the synthetic data side. That part would be big.

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

I'm sympathetic, but I do think it is charming how teh lawyerz believe that you can legislate your way out of a threat model.

"No one would ever do that, it's illegal."

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

Meer dan vierhonderd experts waarschuwen voor EU-voorstel ‘chat control’: ‘We beseffen onvoldoende wat voor gevolgen dat zou hebben’ Onhaalbaar, duur en gevaarlijk voor alle burgers.

Bart Preneel warns EU’s #chatcontrol is dangerous & ineffective: criminals will evade scanners, millions of false positives expected, and end-to-end encryption for all could collapse, threatening privacy, journalists & activists.
