I'm giving a talk today (Weds) about the HOVER McEliece attack ( IACR ePrint 2026/1778 ) at NORDSEC in Aarhus. I have 30 minutes; can even describe McEliece itself! Slides already here: mjos.fi/doc/20261111-nordsec…

Anthropic is releasing an open source library, FlashProve, for provable inference. It was measured on Llama 4 Maverick, a 400B-parameter mixture of experts model. Code: github.com/anthropics/FlashP… Blog post: anthropic.com/research/prova…

My comment to @neilirwin about 20 CEA staff being replaceable by AI generated discussion. My followup essay on the issue & what it means for the future of work, training and the pipeline. We shouldn't avert our gaze from the tough issues we face. econvitals.org/posts/2026-11…

Elliptic curves are not generic. Long time coming. Congrats @crypto_theory and collaborators github.com/bochum-crypto/sub… What I said a week ago: It wouldn't surprise me in the least bit if there were a better factoring or discrete logarithm alg. For factoring: what is the chance that exp(n^1/3) is the right bound? who are we kidding? For discrete log over finite fields: better algorithms over Z_p have followed a decade or so behind those for small-char fields (Coppersmith'84 vs NFS a decade-ish later). Joux gave a quasi-poly alg over small-char fields in the 2010s. Porting to finite fields long overdue. For discrete log over elliptic curves: assuming that elliptic curve groups were "generic" is particularly preposterous given the rich structure they have. All of these ripe for disruption. Unstructured LPN would take me by real surprise, also unstructured LWE to a slightly lesser extent.

My [un]prompted II talk slides: "Math Ability has Consequences – AI Cryptanalysis" available here: mjos.fi/doc/20261028-unp2-ma… (October 28, 2026). Had 20 minutes, so I concentrated on the Classic McEliece story + ngcc.dev stuff.

Nathan: Do you see why this is funny? Elizabeth: Because all these certificates have to be revoked? Nathan: Yes. But do you understand why 4 is a terrible secret key? Elizabeth: Well... it's equally likely as any other value drawn from the uniform distribution.

This P-256 Birthday in mid-August made me crave chocolate-covered strawberries and gave me a hunch. Look who spoke at Crypto’97 within a week of P-256 being generated: iacr.org/conferences/c97/c97…
