The Colossus team were hampered by their wish to use World War II radio equipment, [87] delaying them by a day because of poor reception conditions. Nevertheless, the victor's 1.4 GHz laptop, running his own code, took less than a minute to find the settings for all 12 wheels.
Total war is a concept that has been extensively studied by scholars of conflict and war. One of the most notable contributions to this field of research is the work of Stig Förster, who has identified four dimensions of total war: total purposes, total methods, total mobilisation, and total control.
A similar break into the most secure Japanese diplomatic cipher, designated Purple by the US Army Signals Intelligence Service, started before the US entered the war. Product from this source was called Magic. On the other side, German code breaking in World War II achieved some notable successes cracking British naval and other ciphers.
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 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 success of Zuse's Z3 is often attributed to its use of the simple binary system. [6]: 21 This was invented roughly three centuries earlier by Gottfried Leibniz; Boole later used it to develop his Boolean algebra. Zuse was inspired by Hilbert's and Ackermann's book on elementary mathematical logic Principles of Mathematical Logic.
The W.E.B. Griffin series The Corps is a fictionalized account of United States Navy and Marine Corps intelligence operations in the Pacific Theater during World War II. Many of the main characters in the novels, both fictional and historical, have access to and use intelligence from Magic.
The modern binary number system, the basis for binary code, is an invention by Gottfried Leibniz in 1689 and appears in his article Explication de l'Arithmétique Binaire (English: Explanation of the Binary Arithmetic) which uses only the characters 1 and 0, and some remarks on its usefulness. Leibniz's system uses 0 and 1, like the modern ...
