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.
Military Enigma machine, model "Enigma I", used during the late 1930s and during the war; displayed at Museo scienza e tecnologia Milano, Italy. 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.
The chief German cryptological machine for defense was the Enigma machine. [15] The OKW/Chi and the German armed forces failed to understand how insecure the system was. [30] The Wehrmacht had a generally uneasy feeling regarding Enigma and their own key processes and missed a number of opportunities to definitively prove this. These were:
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 advanced. Possibly the most important codebreaking event of the war was the successful decryption by the Allies of the German "Enigma" Cipher.
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 ...
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 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 ...
Fritz Menzer in his military uniform at the end of the war. Ostwin Fritz Menzer (6 April 1908 in Herrndorf near Niederschöna in Saxony between Chemnitz and Dresden – 25 October 2005 in Bad Homburg vor der Höhe [1]) was a German cryptologist, who before and during World War II, worked in the In 7/VI, the Wehrmacht signals intelligence agency, later working in that was the cipher bureau of ...
