Cryptographer Matthew Green: 15% Chance AI Breaks Trust in Public-Key Crypto
Simon Willison · rss · 2026-10-09
Simon Willison quotes Johns Hopkins cryptographer Matthew Green: a 1% chance we live in "Minicrypt" (public-key encryption is impossible) and a 15% chance we functionally lose confidence in existing public-key algorithms. His core argument: AI's surprise rate vs. the pace of replacing cryptographic standards differ by orders of magnitude — recovery requires preparing in advance.
