Lowell Frazer
Dr. Lowell K. (Jim) Frazer was a mathematician who worked for the National Security Agency (NSA) in the field of cryptography. "Dr. Lowell K. ("Jim") Frazer founded modern cryptographic evaluation for the US government. As a result of his efforts, all cryptography used for classified applications by the U.S. Department of Defense and Intelligence Community is now subject to rigorous scientific evaluation. He influenced the design of most U.S. cryptographic systems fielded prior to 1990. In addition, Dr. Frazer was a prolific writer of technical papers. He was selected as the first Communications Security (COMSEC) mathematician assigned as an integrated member at GCHQ from 1954 to 1956. During this two-year tour, he performed assessments of many cryptographic systems, designed speech cryptosystems, and discovered an analytic technique that would be widely used over the next three decades. Also, he authored a training primer for new COMSEC cryptomathematicians. Dr. Frazer was the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mathematician
A mathematician is someone who uses an extensive knowledge of mathematics in their work, typically to solve mathematical problems. Mathematicians are concerned with numbers, data, quantity, mathematical structure, structure, space, Mathematical model, models, and mathematics#Calculus and analysis, change. History One of the earliest known mathematicians were Thales of Miletus (c. 624–c.546 BC); he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed. He is credited with the first use of deductive reasoning applied to geometry, by deriving four corollaries to Thales' Theorem. The number of known mathematicians grew when Pythagoras of Samos (c. 582–c. 507 BC) established the Pythagoreans, Pythagorean School, whose doctrine it was that mathematics ruled the universe and whose motto was "All is number". It was the Pythagoreans who coined the term "mathematics", and with whom the study of mathemat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Security Agency
The National Security Agency (NSA) is a national-level 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 foreign and domestic intelligence and counterintelligence purposes, specializing in a discipline known as signals intelligence (SIGINT). The NSA is also tasked with the Information assurance, 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 operations, clandestine. The existence of the NSA was not revealed until 1975. 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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cryptography
Cryptography, or cryptology (from grc, , translit=kryptós "hidden, secret"; and ''graphein'', "to write", or ''-logia'', "study", respectively), is the practice and study of techniques for secure communication in the presence of adversarial behavior. More generally, cryptography is about constructing and analyzing 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 (data confidentiality, data integrity, authentication, and non-repudiation) are also central to cryptography. Practical applications of cryptography include electronic commerce, chip-based payment cards, digital currencies, computer passwords, and military communications. Cryptography prior to the modern age was effectively synony ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LKF 2003
Lan Kwai Fong (often abbreviated as LKF) is a small square of streets in Central, Hong Kong. The area was dedicated to hawkers before the Second World War, but underwent a renaissance in the mid-1980s. It is now a popular expatriate haunt in Hong Kong for drinking, clubbing and dining. The street Lan Kwai Fong is L-shaped with two ends joining with D'Aguilar Street. Location Lan Kwai Fong as an area is defined by D'Aguilar Street and the smaller lane, Lan Kwai Fong, an L-shaped, cobble-stoned lane. Both streets turn 90 degrees to form a rectangle. It is near the Mid-Levels. Its eating and drinking establishments are considered upmarket in price and the area is also considered a tourist spot. From the west side of the rectangle, Wo On Lane and Wing Wah Lane extend to host several more spots for drinks and food. The area arguably extends to Wellington Street and Wyndham Street, through to the Hong Kong Fringe Club. It is also home to a small number of art galleries. History ...

National Intelligence Distinguished Service Medal
The National Intelligence Distinguished Service Medal (NIDSM) is a decoration awarded for service to the United States Intelligence Community. The decoration is awarded to any member or contributor to the National Intelligence Community, either civilian or military, who distinguishes themselves by meritorious actions to the betterment of national security in the United States of America, through sustained and selfless service of the highest order. The National Intelligence Distinguished Service Medal was once considered junior to the older National Security Medal. With the establishment of the National Intelligence Awards (NIA) Program by the Office of the Director of National Intelligence (ODNI), the National Intelligence Distinguished Service Medal was the highest decoration in the program. An update to the NIA program added awards and changed precedence, with the NIDSM being succeeded by the Intelligence Community Medal for Valor in the order of precedence. As an authorized U ...

Information Assurance
Information assurance (IA) is the practice of assuring information and managing risks related to the use, processing, storage, and transmission of information. Information assurance includes protection of the integrity, availability, authenticity, non-repudiation and confidentiality of user data. IA encompasses not only digital protections but also physical techniques. These protections apply to data in transit, both physical and electronic forms, as well as data at rest . IA is best thought of as a superset of information security (i.e. umbrella term), and as the business outcome of information risk management. Overview Information assurance (IA) is the process of processing, storing, and transmitting the right information to the right people at the right time. IA relates to the business level and strategic risk management of information and related systems, rather than the creation and application of security controls. IA is used to benefit business through the use of infor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arlington National Cemetery
Arlington National Cemetery is one of two national cemeteries run by the United States Army. Nearly 400,000 people are buried in its 639 acres (259 ha) in Arlington, Virginia. There are about 30 funerals conducted on weekdays and 7 held on Saturday. The other Army cemetery is in Washington, D.C. and is called the U.S. Soldiers' and Airmen's Home National Cemetery. All other national cemeteries are run by the National Cemetery System of the Department of Veterans Affairs. Arlington National Cemetery was established during the U.S. Civil War after the land the cemetery was built upon, Arlington Estate, was confiscated from private ownership following a tax dispute. Listed on the National Register of Historic Places in April 2014, the Arlington National Cemetery Historic District includes the Cemetery, Arlington House, Memorial Drive, the Hemicycle, and Arlington Memorial Bridge.
