Enigma
Produced by Arthur Scherbuis in 1923 aimed at business which had a need for secure communication mainly banks.
The enigma was exhibited at a couple of trade shows in the early 1923 but it attracted the interest of the German military. The result was the withdrawal of the enigma from the market. It was then produced for the German military only.
The enigma machine was a simple cipher machine which had several components to make it work. The original enigma looked like a large typewriter.
{text:list-item} {text:list-item} {text:list-item} {text:list-item} {text:list-item} In 1932 Marian Rejewski a mathematician determined the wiring of the enigma first rotor. Since 1933 Poland was able to read thousands of German messages.
In 1926 the commercial enigma was purchased by the German navy and it was adapted for military use.
There were several different version of the enigma machine made. In 1934 the German navy adopted the Wehrmacht model with its securer plug board and extended the set of rotors to eight.
In 1939 the code breaker found a fundamental flaw with the enigma machine they realised that if they entered the letter as it could not stay that letter.
All messages that were intercepted during the war were sent to Bletchley Park to be decoded.
Alan Turing developed a machine that would help speed up the decoding process. The machine was called the Bombe. It was developed from an idea originally from the polish research.
The Bombe was an electro-mechanical machine that reduced the time needed to break the daily changing enigma keys settings.
The Enigma machine is an electro-mechanical device that relies on a series of rotating 'wheels' or ‘rotors’ to scramble plaintext messages into incoherent cipher text.
For the enigma machine to work correctly the sender and the receiver had to have the same settings....
