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 in southern Nevada, north-northwest of Las Vegas. 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. The USAF and CIA acquired the site in 1955, primarily for flight tests of the Lockheed U-2 aircraft. All research and occurrences in Area 51 are Top Secret/Sensitive Compartmented Information (TS/SCI). The CIA publicly acknowledged the base's existence on 25 June 2013, through a Freedom of Information Act (FOIA) request filed in 2005; it has declassified documents detailing its history and purpose.

A51 Motorway (France)
The A51 autoroute is a partly completed motorway in southeast France. It currently exists as two sections separated by a gap of approximately 85 km, the northern section sometimes referred to as the A51N. It is the long-term project to connect Marseille to Grenoble via Aix-en-Provence, the Durance Valley and the Hautes-Alpes department, providing a high-capacity alternative to the heavily used A7 autoroute, A7 following the Rhône valley. Northern section The section at the Grenoble end, from Varces to Coynelle (17 km), was opened in July 1999. This was extended in March 2007 when the next section, connecting Coynelle to the Col du Fau (10.5 km), was opened in March 2007. This section includes 4.5 km of single carriageway through the Tunnel of Sinard and over the Viaduct de Monestier. The opening of this section has greatly reduced the summer congestion through the commune of Monestier. This northern section is a toll road operated by AREA. Northern section ...

A5/1
A5/1 is a stream cipher used to provide over-the-air communication privacy in the Global System for Mobile Communications, GSM Cell phone, 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 J. Anderson, Ross And ...
