The Enigma machines produced a polyalphabetic substitution cipher.During World War I, inventors in several countries realised that a purely random key sequence, containing no repetitive pattern, would, in principle, make a polyalphabetic substitution cipher unbreakable. [6]
The Enigma machine is a cipher device developed and used in the early- to mid-20th century to protect commercial, diplomatic, and military communication. It was employed extensively by Nazi Germany during World War II, in all branches of the German military. The Enigma machine was considered so secure that it was used to encipher the most top ...
PC Bruno was a Polish–French–Spanish signals–intelligence station near Paris during World War II, from October 1939 until June 1940.Its function was decryption of cipher messages, most notably German messages enciphered on the Enigma machine.
All parts of the German Wehrmacht used the rotor cipher machine to encrypt their secret messages. Enigma.However, different models were used. While the army and air force used the Enigma I almost exclusively, there were different model variants of the Enigma-M for the navy, which usually referred to it as the "Schlüssel M".
The title refers to the French, British and Polish teams which worked on breaking the Enigma cipher, known by shorthand as "X", "Y" and "Z", respectively. The Enigma cipher, produced by the Enigma machine, was used from the 1920s to the end of World War II by Germany—later Nazi Germany—for military and other high security communications.
On 1 February 1942, the Enigma messages began to be encoded using a new Enigma version that had been brought into use. The previous 3-rotor Enigma model had been modified with the old reflector replaced by a thin rotor and a new thin reflector. Breaking Shark on 3-rotor bombes would have taken 50 to 100 times as long as an average Air Force or ...
