Louvre

The Louvre or the Louvre Museum (French: Musée du Louvre, pronounced: [myze dy luvʁ]) (French   ) is one of the world's largest museums and a historic monument in Paris, France. A central landmark of the city, it is located on the Right Bank of the Seine in the 1st arrondissement (ward). Nearly 35,000 objects from prehistory to the 21st century are exhibited over an area of 60,600 square metres (652,300 square feet). The Louvre is the world's most visited museum, receiving more than 9.26 million visitors in 2014.

The museum is housed in the Louvre Palace, originally built as a fortress in the late 12th century under Philip II. Remnants of the fortress are visible in the basement of the museum. The building was extended many times to form the present Louvre Palace. In 1682, Louis XIV chose the Palace of Versailles for his household, leaving the Louvre primarily as a place to display the royal collection, including, from 1692, a collection of ancient Greek and Roman sculpture. In 1692, the building was occupied by the Académie des Inscriptions et Belles Lettres and the Académie Royale de Peinture et de Sculpture, which in 1699 held the first of a series of salons. The Académie remained at the Louvre for 100 years. During the French Revolution, the National Assembly decreed that the Louvre should be used as a museum to display the nation's masterpieces.

Lorde

Ella Marija Lani Yelich-O'Connor (born 7 November 1996), better known by her stage name Lorde (/lɔːrd/), is a New Zealand singer-songwriter. Born in Takapuna and raised in Devonport, Auckland, she became interested in performing as a child. In her early teens, she signed with Universal Music Group and was later paired with the songwriter and record producer Joel Little, who has co-written and produced most of Lorde's works. Her first major release, The Love Club EP, was commercially released in March 2013. The EP reached number two on the national record charts of Australia and New Zealand.

In mid-2013, Lorde released her debut single "Royals". It became an international crossover hit and made Lorde the youngest solo artist to achieve a US number-one single on the Billboard Hot 100 since 1987. In late 2013, she released her debut studio album, Pure Heroine. The record topped the charts of Australia and New Zealand and reached number three on the US Billboard 200. Its following singles include "Tennis Court", "Team", "No Better" and "Glory and Gore". In 2014, Lorde released "Yellow Flicker Beat" as a single from the soundtrack for The Hunger Games: Mockingjay – Part 1.

Paris

Paris (UK: /ˈpærɪs/ PARR-iss; US: ⁱ/ˈpɛərɪs/ PAIR-iss; French: [paʁi]) is the capital and most populous city of France. Situated on the Seine River, in the north of the country, it is in the centre of the Île-de-France region, also known as the région parisienne, "Paris Region". The City of Paris has an area of 105 km² (41 mi²) and a population of 2,241,346 (2014 estimate) within its administrative borders essentially unchanged since 1860.

Since the 19th century, the built-up area of Paris has grown far beyond its administrative borders; together with its suburbs, the whole agglomeration has a population of 10,550,350 (Jan. 2012 census).Paris' metropolitan area spans most of the Paris region and has a population of 12,341,418 (Jan. 2012 census), or one-fifth of the population of France. The administrative region covers 12,012 km² (4,638 mi²), with approximately 12 million inhabitants as of 2014, and has its own regional council and president.

Paris was founded in the 3rd century BC by a Celtic people called the Parisii, who gave the city its name. By the 12th century, Paris was the largest city in the western world, a prosperous trading centre, and the home of the University of Paris, one of the first in Europe. In the 18th century, it was the centre stage for the French Revolution, and became an important centre of finance, commerce, fashion, science, and the arts, a position it still retains today.

SOBER

In cryptography, SOBER is a family of stream ciphers initially designed by Greg Rose of QUALCOMM Australia starting in 1997. The name is a contrived acronym for Seventeen Octet Byte Enabled Register. Initially the cipher was intended as a replacement for broken ciphers in cellular telephony. The ciphers evolved, and other developers (primarily Phillip Hawkes) joined the project.

SOBER was the first cipher, with a 17-byte Linear Feedback Shift Register, a form of decimation called stuttering, and a nonlinear output filter function. The particular configuration of the shift register turned out to be vulnerable to "guess and determine" attacks.

SOBER-2 changed the position of the feedback and output taps to resist the above attacks.

S16 was an expansion to 16-bit words rather than bytes, with an expected increase of security.

Adaptions for and since NESSIE

For the NESSIE call for new cryptographic primitives, three new versions called the t-class were developed; SOBER-t8 was virtually identical to SOBER-2 but did not have sufficient design strength for NESSIE submission; SOBER-t16 and SOBER-t32 were submitted. t32 was a further expansion to 32-bit words, while both ciphers had a more efficient method of computing the linear feedback.

Mona Lisa

The Mona Lisa (/ˌmoʊnə ˈliːsə/; Italian: Monna Lisa [ˈmɔnna ˈliːza] or La Gioconda [la dʒoˈkonda], French: La Joconde [la ʒɔkɔ̃d]) is a half-length portrait of a woman by the Italian artist Leonardo da Vinci, which has been acclaimed as "the best known, the most visited, the most written about, the most sung about, the most parodied work of art in the world".

The painting, thought to be a portrait of Lisa Gherardini, the wife of Francesco del Giocondo, is in oil on a white Lombardy poplar panel, and is believed to have been painted between 1503 and 1506. Leonardo may have continued working on it as late as 1517. It was acquired by King Francis I of France and is now the property of the French Republic, on permanent display at the Louvre Museum in Paris since 1797.

The subject's expression, which is frequently described as enigmatic, the monumentality of the composition, the subtle modeling of forms, and the atmospheric illusionism were novel qualities that have contributed to the continuing fascination and study of the work.
