As Apple expands its bug bounty, I spoke with VP Ivan Krstić about the significance + recent big swings like Memory Integrity Enforcement. These steps protect all users, but particularly those targeted by spyware: “We feel a great moral obligation to defend those users” www.wired.com/story/apple-...

We've built ML-DSA-B, ML-DSA powered by BLAKE3 instead of SHAKE. Up to 20% faster signing, 30% faster verification, 60x pre-hash. Code & details: github.com/PQC-Suite-B With @zooko.bsky.social @aumasson.jp @conordeegan.bsky.social from Project Eleven

Thanks to the American University of Beirut for inviting me to talk about about quantum. Amazing audience, never had that many question. Even bigger thanks to @nadim.computer for making this happen and showing me great places in Lebanon. Slides: www.aumasson.jp/data/talks/A....

as you cancel disney subscriptions, please remember to support your favorite independent media. there are amazing people doing critical work with very little support, and things are only getting harder. here are some of my favorites: www.citationneeded.news/friends/. feel free to post yours below!

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!

"Cryptography makes everything a key management problem" is actually a profoundly optimistic statement.

One of the best things about Posting is you never know what obscure preoccupations your followers have. There will be a guy who has followed you for years and never said anything but then one day you disparage applesauce and he activates like a sleeper agent and dedicates his life to destroying you

TIL: microSD Express uses PCI Express, and is basically a miniature NVMe SSD in a microSD form factor. Up to 1GB/s speeds. This is really cool tech!

My short story collection 𝐆𝐥𝐢𝐭𝐜𝐡𝐞𝐬 is now available as free EPUB/PDF, and still on Kindle, Apple, etc. Readers said it echoes Borges, Murakami (never read them), and DeLillo (never liked him). You judge. The last story pays homage to David Lynch. www.aumasson.jp/glitches/ind...

There's this joke primality testing library that claims 95% accuracy in O(1) time: github.com/mawerty/Is-P... It does so by always returning false. The density of primes between 1 and n approaches 1/ln(n). For a 32-bit int, 4.6% of values are prime, so the code is right 95.4% of the time. 🡇

As I go through this book I’m trying to keep a list of recommendations for cryptographic engineers. It’s short so far, but I expect it’ll get longer as this goes on. Open to suggestions!
