How Alan Turing cracked the Enigma Code. Turing’s work during the Second World War was crucial. Who was Turing and what did he do that was so important?
existing commercial device called Enigma. This handout describes the operation of the Enigma machine in enough detail for you to simulate its function in Assignment #5. A detailed account of how the Bletchley Park mathematicians broke Enigma is available on the CS 106J website.

(Definition) The Enigma Machine was an electromechanical encryption device used by the German armed forces during World War II to encrypt their communications. How to encrypt using Enigma cipher? The Enigma Machine uses a system of rotating wheels (rotors) and electrical wiring to encrypt messages by polyalphabetic substitution.

- The ciphered message has only letters, and no letter in the same position as the initial message.
- On some rotor wheel, the alphabet is fixed, in this case rotor and wheel are the same thing, but sometimes the wheel is not fixed and can be shifte...

The British code breakers worked in shifts around the clock for the whole of the war, using paper and pencil as well as newly invented mechanical techniques to work out the particular Enigma machine settings for each and every single day.

The British worked to break the Enigma at Bletchley Park in England. The code breakers were organized into Huts. These Huts worked in pairs and were known only by their numbers for security reasons. Huts 3 and 6 worked together on deciphering messages from the German Army and Luftwaffe.
Enigma, device used by the German military to encode strategic messages before and during World War II. The Enigma code was first broken by the Poles in the early 1930s. In 1939 the Poles turned their information over to the British, who set up the code-breaking group Ultra, under mathematician Alan M. Turing.

What was the German Enigma machine used for?
Codes and machines developed in the interwar period The need for better ways to secure codes was clear. Dutch Naval officers began work on a machine to encrypt messages. The Germans acquired the patent in 1918. A military model was adopted in 1926. This machine was known as the Enigma.
