Claude AI Just Cracked a Post-Quantum Test Scheme and Found a Faster 7-Round AES Attack
Anthropic's AI model, Claude, has cracked a post-quantum test scheme and found a faster 7-round AES attack. The attack exploits a previously unused symmetry in the lattice behind the signature scheme and is 200 to 800 times faster than previous attacks.

Anthropic's AI model, Claude, has cracked a post-quantum test scheme and found a faster 7-round AES attack. The attack is 200 to 800 times faster than previous attacks and targets HAWK-256, a challenge parameter in the NIST post-quantum standardization process.
Imagine you have a secret code that you want to keep safe. But someone has a powerful computer that can try to guess the code really fast. That's kind of like what happened with Claude AI. It found a way to guess the code much faster than before, but it's still not easy to do. It's like trying to find a needle in a haystack, but the haystack is really, really big.
Analysis
A $60B Vote of Confidence
Anthropic's release of the HAWK-256 key-recovery attack and the 7-round AES-128 attack has significant implications for the security of post-quantum cryptography and the development of new cryptographic protocols. The attack targets HAWK-256, a challenge parameter in the NIST post-quantum standardization process, and is 200 to 800 times faster than previous attacks. This speedup is due to the removal of a 256-way guessing step from an existing meet-in-the-middle attack.
Why Cursor?
Anthropic's AI model, Claude, was used to develop and verify the result over approximately 60 hours in a multi-agent environment. A human researcher provided occasional project-management guidance but was not a lattice-cryptography specialist. The company put the application programming interface (API) cost at about $100,000. The attack remains exponential and does not extend to other NIST signature candidates or lattice cryptography generally.
The Road Ahead
The release of the HAWK-256 key-recovery attack and the 7-round AES-128 attack highlights the potential of AI models in cryptanalysis and the need for further research in this area. It also raises questions about the security of post-quantum cryptography and the development of new cryptographic protocols. As the field continues to evolve, it is essential to consider the potential implications of AI models in cryptanalysis and to develop new cryptographic protocols that are resistant to these types of attacks.
Key points
- Anthropic's AI model, Claude, has cracked a post-quantum test scheme and found a faster 7-round AES attack.
- The attack targets HAWK-256, a challenge parameter in the NIST post-quantum standardization process.
- The attack is 200 to 800 times faster than previous attacks.
- The attack remains exponential and does not extend to other NIST signature candidates or lattice cryptography generally.
The release of the HAWK-256 key-recovery attack and the 7-round AES-128 attack could lead to the development of new cryptographic protocols that are resistant to these types of attacks. This could improve the security of post-quantum cryptography and make it more difficult for attackers to break the code.
The attack could also lead to a decrease in the security of post-quantum cryptography, making it easier for attackers to break the code. This could have significant implications for the security of online transactions and communication.
