This video shows how the famous Enigma rotor cipher machine works. It gives an introduction to the historical background and to the internal workings of the machine.
Enigma was invented by Arthur Scherbius in 1918 for the civil market. After its vanish on the civil market, Enigma caught the interest of the German military ("Wehrmacht"). Then, Enigma was used during WWII and about 30,000 machines were produced. From a cryptographic point of view, Enigma was a huge failure since the Allies (Poland, Britain, and US) were able to break Enigma and decrypt the encrypted messages, leading to a huge intelligence advantage in WWII.
We split the topic 'Enigma' into different parts. The cryptanalysis (keyspace size as well as how to break Enigma) will be shown in the next video.
