Invention of the Cryptography Machine
1915, two Dutch Naval officers invented a machine to encrypt messages. This became known as the Enigma machine -
Patented the Enigma machine
1918, Arthur Scherbius, a German businessman, patented the Enigma machine. -
Mass production of Enigma machine.
Mid 1920s, mass production of Enigma machine with 30,000 machines being sold to the German military over the next 2 decades -
Polish try to crack the code!
The Poles set up a world leading crypt analysis bureau and hired leading mathematicians such as Marian Rejewski. -
Marian builds the Enigma machine
Marian Rejewski built his own model of the Enigma machine without having actually seen it. -
Traitor
In 1931, a German traitor told Rejewski that the Germans routinely changed the daily key indicator setting for the codes. -
More Enigma Machine's Made
To find the daily key, Rejewski build 6 replicas of the Enigma machine and connected them -
The bomb
The new machine could run through more than 17,000 indicator settings. He called this machine, ‘the bomb’ -
Secrecy
The bomb was used to secretly read the traffic from the German Enigma machines for several years. -
German's get complicated
In 1938 Germans added two new roters into the Enigma machine. This made it harder for the Poles to read the traffic -
Allies
The Poles asked their allies, Britian and France to help them with the analysis and codebreaking of the German messages -
Smuggling
The British smuggle out the Enigma replica machines two weeks before Germany invaded Poland -
Bletchley Park
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. -
BOMBS
Turing used 180 ‘bombs’ which clicked round letter-by-letter, 20 every second, until they hit the correct one.
