| Abstract: | Enigma messages can be solved by recovering the message key settings, the ring settings, and the plug settings individually. Recovery of the message key setting is sensitive enough to distinguish the correct rotor order. The method is demonstrated on a 647-letter message, and its performance is estimated for different message lengths and numbers of plugs used. |
