The event was admittedly a marketing stunt for the creators of the AI, Enigma Pattern (opens in new tab), and the cloud server unit used, DigitalOcean (opens in new tab), but it does have some real world applications. While a pretty cool bit of trivia, we thought it was interesting that a book full of cautionary tales was used as the training tool for an AI when barely a month goes by without dire warnings about the dangers of AI. The AI was trained in what German looks like using Grimm’s Fairy tales. Unlike the traditional method of cracking the code, the AI was trained to look for German language, and then work out the statistical probability of the sentence decrypted being the accurate original based on how ‘German’ it was, using 2,000 cloud servers to do the calculations. While it worked, we were treated to a lesson on the Enigma machine by best-selling author Simon Singh (pictured). The code was generated from the sentence “German is a beautiful language”, and ended up with over 53 billion different combinations of letters that needed decrypting. The army and Luftwaffe used a three-rotor Enigma, the navy used a four-rotor Enigma, and it was the navy codes that played a pivotal part in preparing for D-day, so the simulation we saw was modelled on a four-rotor system.
All of those different elements combined mean that you quickly get millions, and then hundreds of millions of different possible outcomes.
