Signal has just rolled out its quantum-safe cryptographic implementation. Ars Technica has a really good article with details: Ultimately, the architects settled on a creative solution. Rather than bolt KEM onto the existing double ratchet, they allowed it to remain more or less the same as it had been …

Peter Gutmann and Stephan Neuhaus have a new paper —I think it’s new, even though it has a March 2025 date—that makes the argument that we shouldn’t trust any of the quantum factorization benchmarks, because everyone has been cooking the books: Similarly, quantum factorisation is performed …

Cybersecurity practitioners are voicing concerns over a recent executive order issued by the White House that guts requirements for: securing software the government uses, punishing people who compromise sensitive networks, preparing new encryption schemes that will withstand attacks from quantum computers, and other existing controls. The executive order (EO …

Microsoft is updating Windows 11 with a set of new encryption algorithms that can withstand future attacks from quantum computers in a move aimed at jump-starting what’s likely to be the most formidable and important technology transition in modern history. Computers that are based on the physics of …
