A quantum-resistant cryptography algorithm that was under consideration as an official US standard has been taken out of the running after an Anthropic security model helped find a flaw that rendered it broken. HAWK was in a third round of testing designed to catch precisely the kinds of flaws Mythos helped uncover. Even before the development, Anthropic was hailing the results of the two cryptographic problems it threw at its Mythos AI security model. Second, the cryptosystems tested were weakened versions of the ones defined in their formal specifications. It’s standard to use the weakened versions in testing, but the real ones are considerably more robust in production settings.
