Claude finds mathematical flaws in post-quantum cryptography and AES
Anthropic researchers using Claude Mythos Preview have discovered improved attacks against two widely studied cryptographic algorithms, demonstrating that frontier AI models can find mathematical weaknesses in encryption schemes, not just bugs in their implementations. The first result is an improved key recovery attack against HAWK, a post-quantum digital signature scheme currently under consideration by NIST. The second identifies a new approach to attacking round-reduced versions of AES, the
