Computer pioneer Alan Turing is best known for his eponymous experiment to test whether artificial and human intelligence can be distinguished. The test he faced during his lifetime was cracking the Enigma code used by Nazi Germany during World War II.
A pair of cryptanalysts say they’ve cracked two long-unsolved messages encoded by Enigma machines using LLMs built by OpenAI and Anthropic.
While Turing and his team of cryptanalysts built an early computer, dubbed the Bombe, that allowed the United Kingdom to translate Enigma messages during the war, a handful of archival messages remain unbroken – usually due to mistranscription or errors by the original encoders.
Carter Leffen, a developer, told OpenAI’s newest model, Astra, to search a database of Enigma messages for an unbroken message and decode it. The model was able to do just that, after doing its own archival research, finding context clues, building a simulator of the Enigma machine, and recovering the plaintext of a message that had baffled researchers since 2005.
Last week, Weirerud validated Leffen’s solution, which he said left him in “awe.”
On September 21, another cryptanalyst, Jack Willis, reached out to Weirerud.
