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.

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...

Ja det høres plausibelt ut

Tjerand Silde @tjesi.bsky.social · 9d

Det burde det ja. Åpenbart eksempel på såkalt "freemium", hvor ting testes gratis, samler inn mye info, og lærer om bruken nå, og så vil det bli big business etterhvert for å beholde tilgang og få benytte avanserte funksjonaliteter.

Olingo: Threshold Lattice Signatures with DKG and Identifiable Abort (Kamil Doruk Gur, Patrick Hough, Jonathan Katz, Caroline Sandsbråten, Tjerand Silde) ia.cr/2025/1789

Abstract. We present Olingo, a framework for threshold lattice signatures that is the first to offer all desired properties for real-world implementations of quantum-secure threshold signatures: small keys and signatures, low communication and round complexity, non-interactive online signing, distributed key generation (DKG), and identifiable abort.

Our starting point is the framework of Gur, Katz, and Silde (PQCrypto 2024). We change the underlying signature scheme to Raccoon (Katsumata et al., Crypto 2024), remove the trapdoor commitments, and apply numerous improvements and optimizations to achieve all the above properties. We provide detailed proofs of security for our new framework and present concrete parameters and benchmarks.

At the 128-bit security level, for up to 1024 parties and supporting 2⁶⁰ signatures, our scheme has 2.6 KB public keys and 9.7 KB signatures; while signing requires communication of 953 KB per party. Using the LaBRADOR proof system (Beullens and Seiler, Crypto 2023), this can be further reduced to 596 KB. An optimistic non-interactive version of our scheme requires only 83 KB communication per party.

Nå må vi ikke være utelukkende negative her, det finnes mange nyttige bruksområder som for eksempel å lage vittige akronymer som tittel på forskningsprosjekter. Slikt kan ikke måles i penger.

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.

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

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."

At the same time, a Commission press release said it expects any age assurance method that's used for child protection purposes to be accurate, reliable, robust, non-intrusive and non-discriminatory.
