The Swiss used a version of Enigma called Model K or Swiss K for military and diplomatic use, which was very similar to commercial Enigma D. The machine's code was cracked by Poland, France, the United Kingdom and the United States; the latter code-named it INDIGO. An Enigma T model, code-named Tirpitz, was used by Japan.
The title refers to the French, British and Polish teams which worked on breaking the Enigma cipher, known by shorthand as "X", "Y" and "Z", respectively. The Enigma cipher, produced by the Enigma machine, was used from the 1920s to the end of World War II by Germany—later Nazi Germany—for military and other high security communications.
The first company was founded in 2000 by Balázs Inotay under the name Enigma Software Inc. and focused on developing SIM-based cryptography and digital signature technology. The company was renamed to Cellum Innovations and Services Inc. and was moved under the Netherlands-based holding company Cellum BV, with a view to international expansion.
With their help," writes Rejewski, "we continued solving Enigma daily keys." [3] The sheets were used by the Poles to make the first wartime decryption of an Enigma message, on 17 January 1940. [7] [9] In May 1940, the Germans once again completely changed the procedure for enciphering message keys (with the exception of a Norwegian network).
