Anthropic：Claude Mythos Preview 发现两种密码算法的弱点

(Getty Images) Anthropic researchers used Claude Mythos Preview to find new weaknesses in two cryptographic methods, the company said Tuesday, including one that is being considered by the National Institute of Standards and Technology for both traditional and quantum computing. In a blog post detailing the work, the frontier AI company called it a “substantial” research advancement, but also emphasized that neither flaw affects software now in use. “The attacks described in these two papers are the strongest attacks we have found to date,” the company wrote in the post. [...] Advertisement The other flaw was found in a weakened version of the Advanced Encryption Standard, or AES, the cipher NIST adopted in 2001 and the most widely used method for scrambling data in transit. Working largely on its own, Mythos invented a mathematical shortcut dubbed the “Möbius Bridge.” While real-world encryption scrambles data through 10 sequential layers, or “rounds,” researchers regularly st

# Discovering cryptographic weaknesses with Claude Discovering cryptographic weaknesses with Claude ## Summary Using Claude Mythos Preview, researchers at Anthropic have discovered improved ways to attack cryptographic algorithms (the mathematical methods used to keep online data private). The first attack significantly weakens HAWK, a digital signature scheme that was built for a post-quantum world. The second identifies a new way to attack round-reduced AES, the most widely used symmetric cipher. These are substantial research advances, but they do not currently affect any production systems. This post describes both findings in more detail and discusses the implications for cryptography in an age of powerful AI models. ## Introduction [...] ## Introduction When we launched Claude Mythos Preview, we showed it was able to autonomously find and exploit vulnerabilities in almost every piece of software we pointed it at. This included several major cryptographic libraries—shared col

Anthropic says its unreleased AI model Claude Mythos Preview has discovered hidden mathematical weaknesses in cryptographic algorithms that researchers had missed for years. The findings were detailed in two research papers focused on improving future cybersecurity. In one study the AI uncovered a flaw in HAWK a post quantum cryptography candidate leading to its withdrawal from consideration as a future security standard. In another the model developed a new mathematical shortcut that speeds up analysis of simplified versions of the Advanced Encryption Standard (AES) by 200 to 800 times.
