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.
Heinz Guderian in the Battle of France, with an Enigma machine. Note one soldier is keying in text while another writes down the results. The major difference between Enigma I (German Army version from 1930), and commercial Enigma models was the addition of a plugboard to swap pairs of letters, greatly increasing cryptographic strength.
German military cryptographers failed to realize that their Enigma, T52 and other systems were insecure. [30] Although many attempts were made to try and validate the security of the Enigma, which the whole of the Wehrmacht secure communication cryptographic infrastructure rested on, they failed.
Decryption of the Enigma Cipher allowed the Allies to read important parts of German radio traffic on important networks and was an invaluable source of military intelligence throughout the war. Intelligence from this source and other high level sources, such as Cryptanalysis of the Lorenz cipher, was eventually called Ultra.
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.
Much of the German cipher traffic was encrypted on the Enigma machine. Used properly, the German military Enigma would have been virtually unbreakable; in practice, shortcomings in operation allowed it to be broken. The term "Ultra" has often been used almost synonymously with "Enigma decrypts".
The Enigma-M4 key machine Key manual of the Kriegsmarine "Der Schlüssel M".. The Enigma-M4 (also called Schlüssel M, more precisely Schlüssel M Form M4) is a rotor key machine that was used for encrypted communication by the German Kriegsmarine during World War II from October 1941.
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 ...
