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 ...
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 ...
Cryptography was used extensively during World War II because of the importance of radio communication and the ease of radio interception. The nations involved fielded a plethora of code and cipher systems, many of the latter using rotor machines. As a result, the theoretical and practical aspects of cryptanalysis, or codebreaking, were much ...
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.
German Army cryptographic systems of World War II were based on the use of three types of cryptographic machines that were used to encrypt communications between units at the division level. These were the Enigma machine, [1] the teleprinter cipher attachment (Lorenz cipher), [2] and the cipher teleprinter the Siemens and Halske T52, [3 ...
A reverse-engineered machine created in 1939 by a team of technicians led by William Friedman and Frank Rowlett could decrypt some of the PURPLE code by replicating some of the settings of the Japanese Enigma machines. This accelerated decoding and the addition of more translators on staff in 1942 made it easier and quicker to decipher the ...
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 ...
Lauenburg was a German weather ship used in the early years of the Second World War to provide weather reports for German shipping, particularly German U-boats.After the German use of such vessels had been identified as a weakness that could be exploited to break the Enigma code, Lauenburg was captured and sunk on 28 June 1941.
