Rejewski designed a machine in 1938, called bomba kryptologiczna, which had broken an earlier version of Germany's Enigma machines by the Polish Cipher Bureau before the Second World War. [ 113 ] A new machine with a different strategy was designed by Turing in 1940 with a major contribution from mathematician Gordon Welchman who goes ...
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 ...
Marian Adam Rejewski (Polish: [ˈmarjan rɛˈjɛfskʲi] ⓘ; 16 August 1905 – 13 February 1980) was a Polish mathematician and cryptologist who in late 1932 reconstructed the sight-unseen German military Enigma cipher machine, aided by limited documents obtained by French military intelligence.
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.
Sekret Enigmy - A 1979 Polish movie about Marian Adam Rejewski, Jerzy Różycki, and Henryk Zygalski, who cracked the first two generations of the Enigma machine. Tajemnica Enigmy - A 1980 series expanding upon the movie. U-571 - A 2000 war film involving the capture of an Enigma machine. Cryptanalysis of the Enigma; List of films about ...
The bombe was designed to discover some of the daily settings of the Enigma machines on the various German military networks: specifically, the set of rotors in use and their positions in the machine; the rotor core start positions for the message—the message key—and one of the wirings of the plugboard.
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 ...
Hans-Thilo Schmidt (13 May 1888 – 19 September 1943) codenamed Asché or Source D, was a German spy who sold secrets about the Enigma machine to the French during World War II. The materials he provided facilitated Polish mathematician Marian Rejewski 's reconstruction of the wiring in the Enigma's rotors and reflector ; thereafter the Poles ...
