AI Applied to Decrypt Medieval Ciphers

๐Ÿงญ The post considers how historical plaintext-hiding techniques, traditionally done by hand, created patterns such as short key phrases that made ciphers vulnerable to statistical analysis. It argues that modern AI and LLMs, being fundamentally statistical models with some randomness, can exploit ciphertext statistics to reconstruct plaintext. The author notes this capability does not automatically make decryption trivial, but highlights the potential for AI to invert statistical patterns in encrypted text.

US issues voluntary frontier AI pre-release review order

๐Ÿ›ก๏ธ The Trump administration has issued an executive order establishing a voluntary framework for developers of powerful AI models to submit a "covered frontier model" to US agencies for up to 30 days of cybersecurity review before wider release. The order explicitly forbids mandatory licensing or preclearance, tasks NSA, CISA and NIST with creating a classified benchmark to define covered models, and directs agencies to harden federal systems and expand AI-enabled defensive tools for smaller operators. It also creates an AI cybersecurity clearinghouse under the Treasury and leaves effectiveness dependent on possible future congressional action.
