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 ...
U-571 is a 2000 submarine film directed by Jonathan Mostow from a screenplay he co-wrote with Sam Montgomery and David Ayer.The film stars Matthew McConaughey, Bill Paxton, Harvey Keitel, Jon Bon Jovi, Jake Weber and Matthew Settle.
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.
The machine was developed by British mathematician Alan Turing, and it was used to decode messages sent by the Nazi military. Bought for $115, a WWII Enigma machine sells for $51,000 Skip to main ...
The Enigma machines were a family of portable cipher machines with rotor scramblers. [1] Good operating procedures, properly enforced, would have made the plugboard Enigma machine unbreakable to the Allies at that time. [2] [3] [4] The German plugboard-equipped Enigma became the principal crypto-system of the German Reich and later of other ...
Milestones was given for "First Breaking of Enigma Code by the Team of Polish Cipher Bureau, 1932-1939", they built the ‘bomba’ – the first cryptanalytic machine to break codes. Their work was a foundation of British code breaking efforts which, with later American assistance, helped end World War II. [6]
The German Enigma used a combination key to control the operation of the machine: rotor order, which rotors to install, which ring setting for each rotor, which initial setting for each rotor, and the settings of the stecker plugboard. The rotor settings were trigrams (for example, "NJR") to indicate the way the operator was to set the machine.
The laboratory was established in 1942 by the Navy and National Cash Register Company to design and manufacture a series of code-breaking machines ("bombes") targeting German Enigma machines, based on earlier work by the British at Bletchley Park (which in turn owed something to pre-war Polish cryptanalytical work). Joseph Desch led the effort. [2]
