Sounds just like the Justice Minister of Denmark, who is pushing Chat Control with a crime-free society narrative. bsky.app/profile/robe...

<<“brain gain” is exactly what we have experienced. As Danish companies have succeeded globally, they have sought out the best and brightest in their respective fields from across the world. The number of foreign workers in Copenhagen has more than doubled in the last decade.>> @madshvid.bsky.social

"Bad news: The proposal is going forward to be voted on on October 14th, and there's still no blocking minority achieved, as Germany reverted its position to undecided. Good news: There is still time to fight back!" Shut this monstrosity down NOW

Earlier this week, CDT joined civil society orgs, companies, & cybersecurity experts, including members of the @globalencryption.org, to urge the Canadian government to withdraw Bill C-2, the so-called Strong Borders Act.

The impact of Alfred Menezes in cryptography is profound. Francisco RH and I are organizing an afternoon session in Latincrypt to celebrate Alfred's career: menezesfest.info If you're coming to Medellín, consider attending!

If ChatControl needs national security exemptions to *not* weaken the security of the state, what makes one believe that it will *not* weaken the security of everyone else? bsky.app/profile/matt...

I know it’s been said again and again, but what does it say about ChatControl that its backers keep explicitly *exempting* law enforcement and national security accounts from content scanning?

Burn it with fire

Brazil bluesky today:

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."

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

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

It was too late when I figured out this was not about cryptography. bsky.app/profile/arju...

I'm here for @dangoodin.bsky.social debunking some wild claims about apparent passkey insecurity made from the Defcon stage, the TL;DR of which is that if your endpoint is compromised, all bets are off arstechnica.com/security/202...

Computer security research is about discovering what someone else out there does not want discovered; everything else is compliance.

The attempts to defend Chat Control (chatcontrol.dk) as "not mass surveillance" are really puzzling to read, because I don't think I've ever come across a better textbook example of mass surveillance, dressed as think-of-the-children legislation.

Proud moment at #CRYPTO 2025! “KLPT²: Algebraic Pathfinding in Dimension Two and Applications” received the Best Paper Award. 🏆 Co-authored by COSIC’s Wouter Castryck & Thomas Decru (presenter). Read it here: eprint.iacr.org/2025/372

We've been using Ed25519 in browsers for over 10 years now (every identity and writer is an Ed25519 pair in Peergos), so we really appreciate this and how much work it has been. The size of nacl.js is 30KB so not a significant benefit, but the web-crypto version is 10x faster!

We are pleased to announce the final* schedule of talks for the 2025 Symposium on Election Security at the DEF CON Voting Village, August 8-10, in quiet, sleepy Las Vegas. Hope to see you there! www.mattblaze.org/papers/VV202... * -subject to change

Something that I have been thinking about with attribution of "PhD level intelligence" or "PhD level expertise" to a machine is that it reflects an increasing trend among these AI bros and their sycophants to want the products of highly skilled training without actually doing any of the work.

I just learned that Claus Schnorr passed away last June, aged 81 — a significant loss for the cryptographic community: mittelhessen-gedenkt.de/traueranzeig...

More than 8,100 people have been expelled to a "third country" since January 20.

Terminei o livro anteontem e gostei MUITO. Assim que puder, vou fazer um fio só sobre ele, mas, para quem lê em inglês, recomendo bastante. É um exposed do grande embuste que Altman e sua empresa são e, com isso, de todo esse projeto trambiqueiro de "gen AI". Seria muito bom que traduzissem para PT.

Nimona is amazing. So many layers about privilege, propaganda, human rights; and a beautiful message about acceptance and second chances. Go watch it!

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

I don’t think anyone is prepared for what they just did w/ ICE. This is not a simple budget increase. It is an explosion - making ICE bigger than the FBI, US Bureau of Prisons, DEA,& others combined. It is setting up to make what’s happening now look like child’s play. And people are disappearing.

The administrations of several American universities are committing acts that will tarnish their image for years.

NEW: The death shadow cast by Musk. “When U.S.-supported soup kitchens were forced to close, babies starved quietly, their mothers said, while older siblings died begging for food.” The world’s richest man did this to the world’s poorest children. Don’t ever forget.

The last point is spot on. The world has been systemically lied about what quantum computers will solve. I understand, why. And - the things a QC can do are pretty impressive. But do have a look at the rest of Scott's slides, linked in the original thread.

I encourage everyone to actually read the dissent. The description of what this government is doing should shock anyone with a conscience. It is unfathomably cruel, indeed sadistic. And yes, *this* is being enabled by the highest court in the nation.

I'm not happy about how the NIST PQC process has somewhat distorted peer review at the IACR conferences. Evaluating the potential impact of contributions based on whatever NIST is doing seems unfair.

the chatbots are fucking so many people up. it’s treated as funny or cringe in most cases now, but we’re going to look back in a few years and ask how we it happen — again. we never learn from past mistakes of buying into hype when the harms are right in front of our eyes if we care to see them.

Super excited that CSF 2025 invited me as one of their keynote speakers! I got to talk about the tension between theory and practice when studying the security of MPC protocols. (Thanks to @owenarden.bsky.social for the photo!)

This is 100% true. And almost every single one stems not from purely technical failures, but failures in the human chain of command declaring that the risk of not mitigating the attack vector was acceptable.

This is the week of Systems Security exams! It is a Spring course at Aarhus University where students dissect a mobile application as part of their final project. kursuskatalog.au.dk/en/course/13...

Ok here's one for the real haters: C is virtually impossible to make memory-safe, but C++ genuinely isn't, and the STL is sufficiently badly designed that it makes that transition /harder/ rather than easier
