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 ...
The German Navy 4-rotor Enigma machine (M4) which was introduced for U-boat traffic on 1 February 1942. The introduction of the fourth rotor was anticipated because captured material dated January 1941 had made reference to the development of a fourth rotor wheel; [ 2 ] indeed, the wiring of the new fourth rotor had already been worked out.
A three-rotor Enigma with plugboard (Steckerbrett) Depiction of a series of three rotors from an Enigma machine. The Enigma is an electro-mechanical rotor machine used for the encryption and decryption of secret messages. It was developed in Germany in the 1920s.
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 machine looked like a typewriter in a wooden box. He called his machine Enigma which is the Greek word for "riddle". Combining three rotors from a set of five, each of the 3 rotor setting with 26 positions, and the plug board with ten pairs of letters connected, the military Enigma has 158,962,555,217,826,360,000 (nearly 159 ...
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 ...
Rejewski had written a "Report of Cryptologic Work on the German Enigma Machine Cipher" in 1942. [91] Before his 1967 retirement, he began writing his "Memoirs of My Work in the Cipher Bureau of Section II of the [Polish] General Staff", which were purchased by the Polish Military Historical Institute , in Warsaw.
