Enigma machine

By Pacey99
  • first idea of the machine

    1915, two Dutch Naval officers invented a machine to encrypt messages. This became known as the Enigma machine.
  • Arthur Scherbius

    1918, Arthur Scherbius, a German businessman, patented the Enigma machine.
  • sold in germany to troops

    Mid 1920s, mass production of Enigma machine with 30,000 machines being sold to the German military over the next 2 decades
  • The Poles set up

    The Poles set up a world leading crypt analysis bureau and hired leading mathematicians such as Marian Rejewski. Marian Rejewski built his own model of the Enigma machine without having actually seen it.
  • a German traitor told Rejewski

    In 1931, a German traitor told Rejewski that the Germans routinely changed the daily key indicator setting for the codes. To find the daily key, Rejewski build 6 replicas of the Enigma machine and connected them. The new machine could run through more than 17,000 indicator settings. He called this machine, ‘the bomb’.
  • The bomb

    The bomb was used to secretly read the traffic from the German Enigma machines for several years.
  • Germans added two new roters

    In 1938 Germans added two new roters into the Enigma machine. This made it harder for the Poles to read the traffic
  • The Poles asked their allies

    The Poles asked their allies, Britian and France to help them with the analysis and codebreaking of the German messages.
  • The British smuggle

    The British smuggle out the Enigma replica machines two weeks before Germany invaded Poland. The smuggled Enigma replicas were taken to the British code . and cypher school at Bletchley Park.
  • Alan Turing

    Alan Turing, a British mathematician at Bletchley Park thought of a different way of using the ‘bombs’ for testing the German codes. Turing used 180 ‘bombs’ which clicked round letter-by-letter, 20 every second, until they hit the correct one.
  • British engineer

    In 1943, British engineer, Tommy Flowers, created Colossus. Hundreds of code breakers at Blechley Park worked round the clock to decipher the German Enigma communications they intercepted
  • Colossus

    Colossus changed the way code breaking was done from electro-mechanical to electronic – it was the first modern day computer. Colossus could read paper tape at 5,000 characters a second.
  • The Allied

    The Allied work on codebreaking played a key role in victories such as D-Day. It shortened the length of WW2.
