Gwido Langer
Lt. Col. Karol Gwido Langer ( Zsolna, Austria-Hungary, 2 September 1894 – 30 March 1948, Kinross, Scotland) was, from at least mid-1931, chief of the Polish General Staff's Cipher Bureau, which from December 1932 decrypted Germany's military Enigma-machine ciphers. Poland's prewar achievements paved the way for Britain's World War II Ultra secret. Life Langer was born in Zsolna, Upper Hungary (today Žilina in Slovakia) but spent his childhood in Cieszyn in Silesia, where his family came from. By mid-1931, according to Polish military historian Władysław Kozaczuk, the Bureau had been formed by merger of the Radio Intelligence Office and the Polish-Cryptography Office. Langer remained at the head of the Cipher Bureau and its successor field agency until the latter was effectively disbanded in November 1942 upon the German occupation of southern France's Vichy "Free Zone." Major Langer had on 15 January 1929, after a tour of duty as chief of staff of the First ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Maksymilian Ciężki
Maksymilian Ciężki (; Samter, Province of Posen (now Szamotuły, Poland), 24 November 1898 – 9 November 1951 in London, England) was the head of the Polish Cipher Bureau's German section (''BS–4'') in the 1930s, during which time—from December 1932—the Bureau decrypted German Enigma messages. During the German invasion of Poland in September 1939, Ciężki escaped to France to continue work on breaking Enigma ciphers. In 1943 he was captured by the Germans and interned in an S.S. concentration camp. Career In the 1930s, Ciężki, as an army captain, was chief of the Polish General Staff Cipher Bureau's German section (''Biuro Szyfrów-4'', abbreviated ''BS-4'').

Interception
In Ball game, ball-playing Competitive sport, competitive team sports, an interception or pick is a move by a player involving a pass of the ball—whether by foot or hand, depending on the rules of the sport—in which the ball is intended for a player of the same team but caught or otherwise brought under control by a player of the opposing team, who thereby usually gains possession of the ball for their team. It is commonly seen in football, including American football, American and Canadian football, as well as association football, rugby league, rugby union, Australian rules football and Gaelic football, as well as any sport by which a loose object is passed between players toward a goal. In basketball, this is called a Steal (basketball), steal. Gridiron football In American football and Canadian football, an interception occurs when a forward pass that has not yet touched the ground is caught by a player of the defensive team. This leads to an immediate change of possess ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Direction Finding
Direction finding (DF), radio direction finding (RDF), or radiogoniometry is the use of radio waves to determine the direction to a radio source. The source may be a cooperating radio transmitter or may be an inadvertent source, a naturally-occurring radio source, or an illicit or enemy system. Radio direction finding differs from radar in that only the direction is determined by any one receiver; a radar system usually also gives a distance to the object of interest, as well as direction. By triangulation, the location of a radio source can be determined by measuring its direction from two or more locations. Radio direction finding is used in radio navigation for ships and aircraft, to locate emergency transmitters for search and rescue, for tracking wildlife, and to locate illegal or interfering transmitters. During the Second World War, radio direction finding was used by both sides to locate and direct aircraft, surface ships, and submarines. RDF systems can be used w ...

Radio
Radio is the technology of communicating using radio waves. Radio waves are electromagnetic waves of frequency between 3 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves. They can be received by other antennas connected to a radio receiver; this is the fundamental principle of radio communication. In addition to communication, radio is used for radar, radio navigation, remote control, remote sensing, and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track ob ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Military Intelligence
Military intelligence is a military discipline that uses information collection and analysis List of intelligence gathering disciplines, approaches to provide guidance and direction to assist Commanding officer, commanders in decision making process, their decisions. This aim is achieved by providing an intelligence analysis, assessment of data from a range of sources, directed towards the commanders' mission requirements or responding to questions as part of operational or campaign planning. To provide an analysis, the commander's information requirements are first identified, which are then incorporated into intelligence collection, analysis, and dissemination. Areas of study may include the operational environment, hostile, friendly and neutral forces, the civilian population in an area of combat operations, and other broader areas of interest. Intelligence activities are conducted at all levels, from tactical to strategic, in peacetime, the period of transition to war, and d ...

Cryptography
Cryptography, or cryptology (from "hidden, secret"; and ''graphein'', "to write", or ''-logy, -logia'', "study", respectively), is the practice and study of techniques for secure communication in the presence of Adversary (cryptography), adversarial behavior. More generally, cryptography is about constructing and analyzing Communication protocol, protocols that prevent third parties or the public from reading private messages. Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, information security, electrical engineering, digital signal processing, physics, and others. Core concepts related to information security (confidentiality, data confidentiality, data integrity, authentication, and non-repudiation) are also central to cryptography. Practical applications of cryptography include electronic commerce, Smart card#EMV, chip-based payment cards, digital currencies, password, computer passwords, and military communications. ...
