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 ...
World War II cryptography. 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 ...
The Enigma machine was used commercially from the early 1920s and was adopted by the militaries and governments of various countries—most famously, Nazi Germany. Cryptanalysis of the Enigma ciphering system enabled the western Allies in World War II to read substantial amounts of Morse-coded radio communications of the Axis powers that had ...
The Lorenz SZ40, SZ42a and SZ42b were German rotor stream cipher machines used by the German Army during World War II. They were developed by C. Lorenz AG in Berlin. The model name SZ was derived from Schlüssel-Zusatz, meaning cipher attachment. The instruments implemented a Vernam stream cipher . British cryptanalysts, who referred to ...
Bombe. A wartime picture of a Bletchley Park Bombe. The bombe ( UK: / bɒmb /) was an electro-mechanical device used by British cryptologists to help decipher German Enigma-machine -encrypted secret messages during World War II. [ 1] The US Navy [ 2] and US Army [ 3] later produced their own machines to the same functional specification, albeit ...
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 ...
In the history of cryptography, the "System 97 Typewriter for European Characters" (九七式欧文印字機 kyūnana-shiki ōbun injiki) or "Type B Cipher Machine", codenamed Purple by the United States, was an encryption machine used by the Japanese Foreign Office from February 1939 to the end of World War II. The machine was an ...
Magic (cryptography) Magic was an Allied cryptanalysis project during World War II. It involved the United States Army 's Signals Intelligence Service (SIS) and the United States Navy 's Communication Special Unit .
