Area 51
Area 51 is the common name of a highly classified United States Air Force (USAF) facility within the Nevada Test and Training Range. A remote detachment administered by Edwards Air Force Base, the facility is officially called Homey Airport or Groom Lake (after the salt flat next to its airfield). Details of its operations are not made public, but the USAF says that it is an open training range, and it is commonly thought to support the development and testing of experimental aircraft and weapons systems. The USAF and CIA acquired the site in 1955, primarily for flight testing the Lockheed U-2 aircraft. The intense secrecy surrounding the base has made it the frequent subject of conspiracy theories and a central component of unidentified flying object (UFO) folklore. It has never been declared a secret base, but all research and occurrences in Area 51 are Top Secret/Sensitive Compartmented Information (TS/SCI). The CIA publicly acknowledged the base's existence on June 25, ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

A5/1
A5/1 is a stream cipher used to provide over-the-air communication privacy in the GSM cellular telephone standard. It is one of several implementations of the A5 security protocol. It was initially kept secret, but became public knowledge through leaks and reverse engineering. A number of serious weaknesses in the cipher have been identified. History and usage A5/1 is used in Europe and the United States. A5/2 was a deliberate weakening of the algorithm for certain export regions. A5/1 was developed in 1987, when GSM was not yet considered for use outside Europe, and A5/2 was developed in 1989. Though both were initially kept secret, the general design was leaked in 1994 and the algorithms were entirely reverse engineered in 1999 by Marc Briceno from a GSM telephone. In 2000, around 130 million GSM customers relied on A5/1 to protect the confidentiality of their voice communications. Security researcher Ross Anderson reported in 1994 that "there was a terrific row between the NAT ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Budapest Gambit
The Budapest Gambit (or Budapest Defence) is a chess opening that begins with the moves: :1. d4 Nf6 :2. c4 e5 Despite an early debut in 1896, the Budapest Gambit received attention from leading players only after a win as Black by Grandmaster Milan Vidmar over Akiba Rubinstein in 1918. It enjoyed a rise in popularity in the early 1920s, but nowadays is rarely played at the top level. It experiences a lower percentage of draws than other main lines, but also a lower overall performance for Black. After 3.dxe5 Black can try the ''Fajarowicz variation'' 3...Ne4 which concentrates on the rapid development of pieces, but the most common move is 3...Ng4 with three main possibilities for White. The ''Adler variation'' 4.Nf3 sees White seeking a in the with his pieces, notably the important d5-square. The ''Alekhine variation'' 4.e4 gives White an important spatial advantage and a strong . The ''Rubinstein variation'' 4.Bf4 leads to an important choice for White, after 4...Nc6 5. ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
