Bitcoin Developers Face New Questions After Anthropic AI Breaks HAWK-256
An unreleased Anthropic AI model has broken a post-quantum signature scheme in about 60 hours, raising concerns about Bitcoin's future. The finding poses no immediate threat to Bitcoin because it uses different cryptographic systems and HAWK-256 was never implemented by the network.
The attack on HAWK-256, which took place after the AI discovered a concealed symmetry in the design of the algorithm, reduced its effectiveness by 50%. This breakthrough illustrates how AI can accelerate cryptanalysis and make it faster and cheaper to test advanced cryptographic systems. The cost of this specific test was around $100,000.
The cryptography community has reacted quickly, with some experts declaring HAWK-256 dead. Bitcoin developers are concerned about the potential impact on post-quantum cryptography, as AI-assisted cryptanalysis can now be performed in a relatively short period. The economics of this type of testing are changing, making it more feasible for researchers to test and potentially break advanced cryptographic systems.
