Matthew Green：AI 冲击下公钥加密或面临信任危机
Quoting Matthew Green
密码学家 Matthew Green 称，有 1% 的概率我们生活在 Minicrypt 世界（公钥加密不可能存在），另有 15% 的概率会实质性地对现有公钥加密算法失去信心。他指出，AI 制造意外发现的速度与人类替换标准的速度相差数个数量级，只有提前做好准备才能从这类冲击中恢复。

Everyone is very concerned about being respectable, so I’m going to be the goofball who raises worst-case possibilities. I think there is a 1% chance we live in Minicrypt, and a 15% chance we functionally lose confidence in our existing public-key encryption algorithms. [...]
The problem here is that the speed of AI producing surprises, and the speed of human beings replacing standards (even with the very best AI assistance) are just orders of magnitude different. You only recover from a surprise like this if you do the preparation in advance.
— Matthew Green, on Twitter. I looked it up and Minicrypt is Russell Impagliazzo’s hypothetical world in which public-key encryption is impossible.
