Help Break Original Enigma Messages 272

Stereo writes "The Enigma Machine was cracked in Poland in 1932, but three messages remain unbroken, despite having been intercepted in the North Atlantic in 1942. The M4 Project, named after the four rotor Enigma M4 used for encryption, is a distributed computing effort to break them. One message has already been deciphered successfully!"

    While it is true what you say, I will point out that "enigma" messages originated from a lot of different networks, all with their own codebooks, eg. Luftwaffe (airforce), Abwher (intelligence), and Hehr (army) messages etc, where all encoded with different keys. These different networks where further segmented into theater of operations, meaning that breaking Hehr enigma messages from North Africa, would not yield the key for reading Hehr messages originating from France. Further more, all keys would changed daily, meaning that the British would have to start all over every day.

    So getting the daily subkey from a bungled weather report, would only help the British to read messages from a particular branch, in a limited area, for a period of just 24 hours.
