In general, however, German performance in code breaking was weak due to the fragmentation of responsibility and specialized personnel. [ citation needed ] The Navy's B-Dienst was an exception to the rule, although its successes largely ended when the Allies began using more sophisticated encryption methods by 1943.
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-secret messages. [1] The Enigma has an electromechanical rotor mechanism that scrambles the 26 letters of the alphabet. In typical use, one person enters ...
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.
It was not until early in 1941 that the first breaks were made into German Army Enigma traffic, and it was the spring of 1942 before it was broken reliably, albeit often with some delay. [141] It is unclear whether the German Army Enigma operators made deciphering more difficult by making fewer operating mistakes. [142]
From the early 1930s to the start of the war, Germany had a good understanding of, and indeed a lead in, both cryptoanalytic and cryptographic cryptology services. The various agencies had cracked the French–English inter-allied cipher, the Germans with some help from the Italian Communications Intelligence Organization stole American diplomatic codes, and codes taken from the British ...
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 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.
On entering World War II in June 1940, the Italians were using book codes for most of their military messages. The exception was the Italian Navy , which after the Battle of Cape Matapan started using the C-38 version of the Boris Hagelin rotor-based cipher machine , particularly to route their navy and merchant marine convoys to the conflict ...
