SHACAL-1
SHACAL-1 (originally simply SHACAL) is a 160-bit block cipher based on SHA-1, and supports keys from 128-bit to 512-bit. SHACAL-2 is a 256-bit block cipher based upon the larger hash function SHA-256. Both SHACAL-1 and SHACAL-2 were selected for the second phase of the NESSIE NESSIE (New European Schemes for Signatures, Integrity and Encryption) was a European research project funded from 2000 to 2003 to identify secure cryptographic primitives. The project was comparable to the NIST AES process and the Japanese Gov ... project. However, in 2003, SHACAL-1 was not recommended for the NESSIE portfolio because of concerns about its key schedule, while SHACAL-2 was finally selected as one of the 17 NESSIE finalists. Design SHACAL-1 is based on the following observation of SHA-1: The hash function SHA-1 is designed around a compression function. This function takes as input a 160-bit state and a 512-bit data word and outputs a new 160-bit state after 80 rounds. The hash func ...

Selected Areas In Cryptography
Selected Areas in Cryptography (SAC) is an international cryptography conference (originally a workshop) held every August in Canada since 1994. The first workshop was organized by Carlisle Adams, Henk Meijer, Stafford Tavares and Paul van Oorschot. Through 1999, SAC was hosted at either Queen's University or Carleton University, but starting in 2000, locations have ranged across Canada. SAC has featured research presentations on many cryptographic topics, with a traditional focus on the design and analysis of block ciphers. SAC is regarded as a high-quality venue for presenting cryptographic results, and is the only cryptography conference held annually in Canada. Since 2003, SAC has included an invited lecture called the Stafford Tavares Lecture, in honor of one of its original organizers and strongest supporters. Each year, SAC features four topics: # Design and analysis of symmetric key primitives and cryptosystems including block and stream ciphers, hash functions, MAC alg ...

Samos
Samos (, also ; el, Σάμος ) is a Greek island in the eastern Aegean Sea, south of Chios, north of Patmos and the Dodecanese, and off the coast of western Turkey, from which it is separated by the -wide Mycale Strait. It is also a separate regional unit of the North Aegean region. In ancient times, Samos was an especially rich and powerful city-state, particularly known for its vineyards and wine production. It is home to Pythagoreion and the Heraion of Samos, a UNESCO World Heritage Site that includes the Eupalinian aqueduct, a marvel of ancient engineering. Samos is the birthplace of the Greek philosopher and mathematician Pythagoras, after whom the Pythagorean theorem is named, the philosophers Melissus of Samos and Epicurus, and the astronomer Aristarchus of Samos, the first known individual to propose that the Earth revolves around the sun. Samian wine was well known in antiquity and is still produced on the island. The island was governed by the semi-autonomous ...

New Delhi
New Delhi (, , ''Naī Dillī'') is the capital of India and a part of the National Capital Territory of Delhi (NCT). New Delhi is the seat of all three branches of the government of India, hosting the Rashtrapati Bhavan, Parliament House, and the Supreme Court of India. New Delhi is a municipality within the NCT, administered by the NDMC, which covers mostly Lutyens' Delhi and a few adjacent areas. The municipal area is part of a larger administrative district, the New Delhi district. Although colloquially ''Delhi'' and ''New Delhi'' are used interchangeably to refer to the National Capital Territory of Delhi, both are distinct entities, with both the municipality and the New Delhi district forming a relatively small part of the megacity of Delhi. The National Capital Region is a much larger entity comprising the entire NCT along with adjoining districts in neighbouring states, including Ghaziabad, Noida, Gurgaon and Faridabad.

PostScript
PostScript (PS) is a page description language in the electronic publishing and desktop publishing realm. It is a dynamically typed, concatenative programming language. It was created at Adobe Systems by John Warnock, Charles Geschke, Doug Brotz, Ed Taft and Bill Paxton from 1982 to 1984. History The concepts of the PostScript language were seeded in 1976 by John Gaffney at Evans & Sutherland, a computer graphics company. At that time Gaffney and John Warnock were developing an interpreter for a large three-dimensional graphics database of New York Harbor. Concurrently, researchers at Xerox PARC had developed the first laser printer and had recognized the need for a standard means of defining page images. In 1975-76 Bob Sproull and William Newman developed the Press format, which was eventually used in the Xerox Star system to drive laser printers. But Press, a data format rather than a language, lacked flexibility, and PARC mounted the Interpress effort to create a succ ...
