Enigma Machine for Sale on eBay

Posted by samzenpus on from the break-your-own-codes dept.

RagingMaxx writes "An Italian antiques dealer has recently put to auction a mint condition, fully operational Enigma machine on eBay. The machine, dated circa 1938, will be sold to the highest bidder in just over a week, but after 30 hours of bidding the price has already surpassed $12,000 US. For those of you who can't afford the real thing, why not make your own?"

    I hear that the MPAA is interested in purchasing the machine - as they've heard that it has unbreakable encryption.

    Looks like it's only the 3 gear model. If it was the four gear model, I surely would have purchased it :P.

      When thinking of answers to questions like that I find it impossible to separate cryptomonicon from reality.

      True, but at least a half dozen of them were successfully recovered by the Allies during the war. The movie U-571 is a dramatization of one of these successes, and the credits at the end of the movie list a number of other incidents where Enigmas were captured. No idea what happened to all of these though. My bet would be that either they ended up in museums or were destroyed after the war.

      While your post is correct about the film being a 'dramatisation', that film was some serious fiction. The Americans weren't even in the war when the first Enigmas were captured. The first capture of note [not an Enigma machine itself but something more vital] was grabbed from U110 by Sub-Lieutenant David Balme, aboard HMS Bulldog on the 9th May 1941 who was subsequently awarded a DSC for his actions. Before leaving the submarine, he grabbed a sealed envelope that contained the hyper-secret starting positions used by the Kriegsmarine.

      This one looks like an Enigma 1 [Wermacht or Services Enigma]. They were also used by government and banks so this one could have been ex-government etc.

      The important of cracking Enigma cannot ever be overstated. There is a general agreement amongst historians that the Allies ability to read the German's encrypted traffic shaved a couple of years off the war. I would encourage our American brethren to read the book 'Enigma:The Battle for the Code' by Simon Sebag-Montefiore. Its an exceptionally good and instructive read about the whole Enigma issue.

      I would go as far and say that cracking Enigma prevented nuclear bombs over Europe. Nevertheless, the names of Rejewski, Turing and others have been forgotten or never known by the public. It's a shame.

      The important of cracking Enigma cannot ever be overstated.

      Actually, it can be (and often is) overstated. The fascination with Enigma, among both the general public and the historians, often obscures (or fails to mention at all) the fact that the codebreaking effort was but one portion of the overall electronic intelligence effort. Especially in the Battle of the Atlantic where Huff-Duff and more conventional technques (like traffic analysis) yielded vast amounts of vital intelligence data.
       
      Even with decrypted ciphertext, it always took considerable analysis to break the code(s) the messages used in the text for further security. (In the Atlantic the Allies, for example, never got a break like 'AF is short of fresh water'.)

    this page claims modern computers can crack an Enigma message in "a few minutes".
    But a recent effort to crack some M4 messages using distributed computing estimated some 10,000 PC-hours to break a message.

      In theory there were a astronomically large number of possible combinations (3 x 10^114) of rotor wirings, pluggable wirings, and rotor positions in a three-rotor Enigma machine. That key space is incredibly far beyond the capabilities of modern computers to search. However, in reality there were only three rotors implemented at first (later there were five, from which three were chosen for each day). The allies knew the wiring of the three rotors before the war began, and deduced the other two. So instead of having to try all the theoretical combinations of rotors, they only had to try the combinations of the ones that actually were implemented.

      The subs had a four-rotor machine, but the operators made a fatal mistake. In order for messages to be read on three-rotor machines, an operator encrypted the same message twice--once with three rotors and once with four. That gave the codebreakers the information they needed to deduce the fourth rotor. They built a machine for breaking the Enigma codes which, given what they knew about the rotors, they could break them quickly enough to be extremely useful in the war.

      Also a German U-boat was captured, along with a code book showing the rotor positions for the next few months. With that information they learned enough about the four rotor system to be able to break those messages also.

  8. The Enigmas were not the only things destroyed by Bearhouse · · Score: 5, Informative

    In the interests of 'National Security', the British Govt. broke up the team that broke the Enigma codes, and 'classified' or destroyed the equipment that they had imagined, designed AND built to help. Thereby setting back the UK IT industry by - oh, let's say 10 years, IMHO.

    Not gonna Karma-whore by posting a zillion Wikiped links, but it's all there if you're interested and don't know the story. Worth a read, newbies, since a lot of what you now take for granted was developed by these folks.

    That is not a Wehrmacht "symbol", but the coat of arms of the Third Reich, which in turn is a perverted version of its "predecessor" from the German Empire.

    The Wehrmacht symbol, by the way, is a stylized Iron Cross, which is also the current emblem of German armed forces (and has been since the German Empire).

    A *very* interesting account of the Enigma's history from a postwar Polish perspective, translated in East Germany (I got my copy from the gift shop at the Rundfunkmuseum in Nuremberg). This is a translation from the Polish original.

    German Translation: "Im Banne Der Enigma" (Under The Spell Of The Enigma)
    Original title: "W krgu Enigmy", published in Warsaw in 1979
    Author: Wladyslaw Kozaczuk

    Translation published by: Militärverlag der Deutschen Demokratischen Republik
    (translator's name not listed)
    ISBN 3-327-00423-4

    In addition to its rather interesting political perspective, the book has an extremely detailed account of the Polish Intelligence Service's work on Enigma, including material I'd not seen in most of the more accessible Western literature on Enigma. In essence, the Polish crypto boffins had Enigma cracked (including automated cracking machines) before the war even started, but lacked the resources to scale up their efforts as the machines were upgraded (addition of the plugboard and new rotors); that, and the German occupation of Poland and later France, led them to share their findings with Britain, and the history most folks hear about.

    BTW, WRT the "Enigma-E" electronic Enigma machine, I highly recommend it. I still get a kick out of decrypting messages with the one I built (in its nifty wooden case). Well worth the cost for those who've gotten the "Enigma virus".
