Anthropic AI Model Weakens HAWK Minimum Key Strength in 60 Hours

Odaily Odaily Planet Daily News: Anthropic's Claude Mythos Preview model has identified a flaw in the proposed HAWK digital signature scheme, effectively halving its minimum key strength. HAWK is one of the candidate schemes for replacing current network and bank signatures in a post-quantum environment.
This AI-driven attack took approximately 60 hours and cost about $100,000 in computing power, reducing the effort required to crack HAWK's minimum parameter set from approximately 2^64 operations to 2^38 operations, and diminishing the attractiveness of larger compensating key sizes.
Current Bitcoin and Ethereum signatures remain unaffected. These results indicate that classical cryptanalysis attack capabilities are improving, while Bitcoin and other networks continue to discuss the timing and method of migrating to quantum-resistant cryptography.
