The limits of zero-knowledge for age-verification | Brave
ZKPs are often advanced as a technical remedy, promising privacy-preserving attestations of age or eligibility. Yet their deployment in practice exposes both conceptual and practical limits.

Anonymous credentials are going to have a big year. In the realm of "fancy" cryptography, they're perhaps the most important primitive we'll need to make PQ. Where do we stand? Lena Heimberger spent part of the summer finding out.

Improving the trustworthiness of Javascript on the Web
Today, there's no way to audit a site’s client-side code as it changes, making it hard to trust sites that use cryptography. We preview a specification we coauthored that adds auditability to the web.

The bad guy's plan falls apart because it relies on tricking the crew to fire on a helpless ship. Picard may not have memories, but he still has morals. "I do not fire on defenseless people" should be the absolute floor for ethics in military leadership, but the 1990's were a different time

You don’t need quantum hardware for post-quantum security
Post-quantum cryptography protects against quantum threats using today’s hardware. Quantum tech like QKD may sound appealing, but it isn’t necessary or sufficient to secure organizations.

Even the strongest among us feel weak at times. Even the smartest of us feel stupid at times. Even the most confident feel doubt. There is no shame in feeling that you are not always at your best. A true warrior feels these things, but strives for better. That way lies glory.

I don't do plugs often, but if your company relies on work like this being done professionally, Geomys (

Exactly the same as the first time. People with prior orders of removal, that were allowed to stay for humanitarian or diplomatic reasons, and have been checking in with ICE for years, are the low hanging fruit and so get grabbed at check-ins and detained and deported.

A just heard that a colleague who researches anti-censorship tools (the kind that let you use the Internet in hostile regimes where the Internet is filtered) just got his NSF CAREER grant pulled. Presumably because the political commissars grepped “censorship”.

1. LLM-generated code tries to run code from online software packages. Which is normal but 2. The packages don’t exist. Which would normally cause an error but 3. Nefarious people have made malware under the package names that LLMs make up most often. So 4. Now the LLM code points to malware.
