| | Enigma machine - Wikipedia, the free encyclopedia |
 | | Replicas of the machine are available in various forms, including an exact reconstructed copy of the Naval M4 model, an Enigma implemented in electronics (Enigma-E), various computer software simulators and paper-and-scissors analogues. | | | Users of Enigma were assured of its security by the large number of possibilities; it was not feasible for an adversary to even begin to try every possible configuration in a brute force attack. | | | Enigma without a plugboard — "unsteckered" Enigma — can be solved relatively straightforwardly using hand methods; these techniques are generally defeated by the addition of a plugboard, and codebreakers resorted to special machines to solve it. |

| | Among the special machines that were invented and further developed over several decades to simplify the routine enciphering and deciphering of code, the Enigma machine is probably the most well known example around the world. | | | From the time of Enigma onwards, the history of computer technology was strongly influenced by enciphering techniques and the efforts expended in breaking unknown codes. | | | Together with other ciphering devices, two of these machines are held by the Computer department (sorry, these informations are only in German). |

| | Hebern's idea was the base for many similar machines, developed in several other countries. | | | In 1939 the Bureau was no longer able to break the codes due to increased sophistication in the design, new procedures and lack of funds for the code breakers. | | | The Wehrmacht revised this machine, adding the plugboard and a different rotor advancing mechanism. |

| | Even with all of this knowledge about the machine, the Polish informed the French that without a key to the correct position of the rotors any decryption would be impossible. | | | Therefore, unless one knew which rotor went where, and what position each rotor started in, the Enigma machine was useless. | | | The documents also described the plug board, which was not present on the commercial version of the machine that the Polish had bought. |

| | For a very beautifully designed Enigma Simulator (that you can download to your computer), I highly recommend this program created by Dirk Rijmenants. | | | That is why, even though the starting position of my sample is "MCK" - the rotors are moved to the "MCL" position while decoding the first letter. | | | One of the benefits of building and using a model like this is that you can gain a deeper understanding of the details of the Enigma machine. |
