Lambros Callimahos
Lambros Demetrios Callimahos (December 16, 1910 – October 28, 1977) was a US Army cryptologist and a flute player. Early life and education Callimahos was born in Alexandria of Greek parents; the family emigrated to the United States when he was four. His father was a journalist. His main interests at school were in chemistry, physics and medicine. He did not show interest in music until the age of fourteen when he entered high school in Asbury Park. Callimahos earned a degree in law from Rutgers in accord with his fathers' wishes, but attended Juilliard music school at the age of nineteen and graduated with a degree in 1933. While he started at the bottom of the class, he became head of his class in his second year after encouragement from his teacher, Arthur Lora. After graduation, he continued study in Europe. Musical career His musical debut was in Munich in 1935 and was heralded as ''Meisterfloetist''. He also played in Vienna and that autumn played an all-Bach progra ...

It has its roots in the Continental Army, formed on 14 June 1775 to fight against the British for independence during the American Revolutionary War (1775–1783). After the Revolutionary War, the Congress of the Confederation created the United States Army on 3 June 1784 to replace the disbanded Continental Army.Library of CongressJournals ...

Mozarteum
Mozarteum University Salzburg ( German: ''Universität Mozarteum Salzburg'') is one of three affiliated but separate (it is actually a state university) entities under the "Mozarteum" name in Salzburg municipality; the International Mozarteum Foundation and the Mozarteum Orchestra Salzburg are the other two. It specializes in music, the dramatic arts, and to a lesser degree graphic arts. Like its affiliates it was established in honour of Salzburg-born musician Wolfgang Amadeus Mozart. History and clarification In 1841, Mozart's widow Constanze Weber Mozart founded the first of the “Mozarteum” entities: the “Cathedral Music Association and Mozarteum,” whose mission was the “refinement of musical taste with regard to sacred music and concerts.” The association operated as predecessor to the Mozarteum Orchestra Salzburg through the 19th century and was at the heart of the city’s musical life, offering concerts and related activities. It assumed its present name ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dundee Society
The Dundee Society was a society of graduates of CA-400, a National Security Agency course in cryptology devised by Lambros D. Callimahos, which included the Zendian Problem (a practical exercise in traffic analysis and cryptanalysis). The class was held once a year, and new members were inducted into the Society upon completion of the class. The Society was founded in the mid-1950s and continued on after Callimahos' retirement from NSA in 1976. The last CA-400 class was held at NSA in 1979, formally closing the society's membership rolls. The society took its name from an empty jar of Dundee Marmalade that Callimahos kept on his desk for use as a pencil caddy. Callimahos came up with the society's name while trying to schedule a luncheon for former CA-400 students at the Fort George G. Meade, Ft. Meade Officers' Club; being unable to use either the course name or the No such agency, underlying government agency's name for security reasons, he spotted the ceramic Dundee jar and ...

National Security Agency
The National Security Agency (NSA) is an intelligence agency of the United States Department of Defense, under the authority of the director of national intelligence (DNI). The NSA is responsible for global monitoring, collection, and processing of information and data for global intelligence and counterintelligence purposes, specializing in a discipline known as signals intelligence (SIGINT). The NSA is also tasked with the protection of U.S. communications networks and information systems. The NSA relies on a variety of measures to accomplish its mission, the majority of which are clandestine. The NSA has roughly 32,000 employees. Originating as a unit to decipher coded communications in World War II, it was officially formed as the NSA by President Harry S. Truman in 1952. Between then and the end of the Cold War, it became the largest of the U.S. intelligence organizations in terms of personnel and budget. Still, information available as of 2013 indicates that the C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Army Security Agency
The United States Army Security Agency (ASA) was the United States Army, United States Army's signals intelligence branch from 1945 to 1977. The Latin motto of the Army Security Agency was ''Semper Vigilis'' (Vigilant Always), which echoes the declaration, often mistakenly attributed to Thomas Jefferson, that "q:Thomas Jefferson#Misattributed, The price of liberty is eternal vigilance." Although most ASA units focused upon SIGINT (signals intelligence) most if not all ASA units contained HUMINT (human intelligence) specialists as well, mostly interrogators and counter-intelligence specialists. At the end of the Cold War era, some ASA units also were staffed with ELINT (electronic intelligence) specialists and warrant officers, which incorporated field Electronic countermeasure, ECM (electronic counter-measures and field Electronic counter-countermeasures, ECCM (electronic counter-countermeasures) such as tactical jammers, direction finders, electronic signal decoys, and captured ...

SIGINT
Signals intelligence (SIGINT) is the act and field of intelligence-gathering by interception of ''signals'', whether communications between people (communications intelligence—abbreviated to COMINT) or from electronic signals not directly used in communication (electronic intelligence—abbreviated to ELINT). As classified and sensitive information is usually encrypted, signals intelligence may necessarily involve cryptanalysis (to decipher the messages). Traffic analysis—the study of who is signaling to whom and in what quantity—is also used to integrate information, and it may complement cryptanalysis. History Origins Electronic interceptions appeared as early as 1900, during the Boer War of 1899–1902. The British Royal Navy had installed wireless sets produced by Marconi on board their ships in the late 1890s, and the British Army used some limited wireless signalling. The Boers captured some wireless sets and used them to make vital transmissions. Since the Bri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japanese Language
is the principal language of the Japonic languages, Japonic language family spoken by the Japanese people. It has around 123 million speakers, primarily in Japan, the only country where it is the national language, and within the Japanese diaspora worldwide. The Japonic family also includes the Ryukyuan languages and the variously classified Hachijō language. There have been many Classification of the Japonic languages, attempts to group the Japonic languages with other families such as Ainu languages, Ainu, Austronesian languages, Austronesian, Koreanic languages, Koreanic, and the now discredited Altaic languages, Altaic, but none of these proposals have gained any widespread acceptance. Little is known of the language's prehistory, or when it first appeared in Japan. Chinese documents from the 3rd century AD recorded a few Japanese words, but substantial Old Japanese texts did not appear until the 8th century. From the Heian period (794–1185), extensive waves of Sino-Ja ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cryptanalysis
Cryptanalysis (from the Greek ''kryptós'', "hidden", and ''analýein'', "to analyze") refers to the process of analyzing information systems in order to understand hidden aspects of the systems. Cryptanalysis is used to breach cryptographic security systems and gain access to the contents of encrypted messages, even if the cryptographic key is unknown. In addition to mathematical analysis of cryptographic algorithms, cryptanalysis includes the study of side-channel attacks that do not target weaknesses in the cryptographic algorithms themselves, but instead exploit weaknesses in their implementation. Even though the goal has been the same, the methods and techniques of cryptanalysis have changed drastically through the history of cryptography, adapting to increasing cryptographic complexity, ranging from the pen-and-paper methods of the past, through machines like the British Bombes and Colossus computers at Bletchley Park in World War II, to the mathematically advanced ...
