The National Center for Medical Intelligence ( NCMI ), formerly known as the Armed Forces Medical Intelligence Center, is a component of the United States Defense Intelligence Agency (DIA) responsible for the production of medical intelligence and all-source intelligence on foreign health threats and other medical issues to protect U.S ...
SIGABA. SIGABA cipher machine at the National Cryptologic Museum, with removable rotor assembly on top. In the history of cryptography, the ECM Mark II was a cipher machine used by the United States for message encryption from World War II until the 1950s. The machine was also known as the SIGABA or Converter M-134 by the Army, or CSP-888/889 ...
LC Class. TK7885.4 .K53. The Soul of a New Machine is a non-fiction book written by Tracy Kidder and published in 1981. It chronicles the experiences of a computer engineering team racing to design a next-generation computer at a blistering pace under tremendous pressure. The machine was launched in 1980 as the Data General Eclipse MV/8000.
The United States Naval Computing Machine Laboratory ( NCML) was a highly secret design and manufacturing site for code-breaking machinery located in Building 26 of the National Cash Register (NCR) company in Dayton, Ohio and operated by the United States Navy during World War II. It is now on the List of IEEE Milestones, [1] and one of its ...
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 Kurzsignale code was intended to shorten transmission time to below the time required to get a directional fix. It was not primarily intended to hide signal contents; protection was intended to be achieved by encoding with the Enigma machine. A copy of the Kurzsignale code book was captured from German submarine U-110 on 9 May 1941.
The Hebern Rotor Machine was an electro-mechanical encryption machine built by combining the mechanical parts of a standard typewriter with the electrical parts of an electric typewriter, connecting the two through a scrambler. It is the first example (though just barely) of a class of machines known as rotor machines that would become the ...
The M-209 was designed by Swedish cryptographer Boris Hagelin in response to a request for such a portable cipher machine, and was an improvement of an earlier machine, the C-36. The M-209 is about the size of a lunchbox , in its final form measuring 3 + 1 ⁄ 4 by 5 + 1 ⁄ 2 by 7 inches (83 mm × 140 mm × 178 mm) and weighing 6 pounds (2.7 ...
