NIST Hash Function Competition
The NIST hash function competition was an open competition held by the US National Institute of Standards and Technology (NIST) to develop a new hash function called SHA-3 to complement the older SHA-1 and SHA-2. The competition was formally announced in the ''Federal Register'' on November 2, 2007. "NIST is initiating an effort to develop one or more additional hash algorithms through a public competition, similar to the development process for the Advanced Encryption Standard (AES)." The competition ended on October 2, 2012, when NIST announced that Keccak would be the new SHA-3 hash algorithm. The winning hash function has been published as NIST FIPS 202 the "SHA-3 Standard", to complement FIPS 180-4, the '' Secure Hash Standard''. The NIST competition has inspired other competitions such as the Password Hashing Competition. Process Submissions were due October 31, 2008 and the list of candidates accepted for the first round was published on December 9, 2008. NIST held ...

Joan Daemen
Joan Daemen (; born 1965) is a Belgians, Belgian cryptographer who is currently professor of digital security (symmetric encryption) at Radboud University. He co-designed with Vincent Rijmen the Rijndael cipher, which was selected as the Advanced Encryption Standard (AES) in 2001. More recently, he co-designed the Keccak cryptographic hash, which was NIST hash function competition, selected as the new SHA-3 hash by NIST in October 2012. He has also designed or co-designed the MMB (cipher), MMB, Square (cipher), Square, SHARK (cipher), SHARK, NOEKEON, 3-Way, and BaseKing block ciphers. In 2017 he won the Levchin Prize for Real World Cryptography "for the development of AES and SHA3". He describes his development of encryption algorithms as creating the bricks which are needed to build the secure foundations online. In 1988, Daemen graduated in electro-mechanical engineering at the Katholieke Universiteit Leuven. He subsequently joined the COSIC research group, and has worked on ...

SANDstorm
A dust storm, also called a sandstorm, is a meteorological phenomenon common in arid and semi-arid regions. Dust storms arise when a gust front or other strong wind blows loose sand and dirt from a dry surface. Fine particles are transported by saltation and suspension, a process that moves soil from one place and deposits it in another. These storms can reduce visibility, disrupt transportation, and pose serious health risks. Over time, repeated dust storms can reduce agricultural productivity and contribute to desertification. The arid regions of North Africa, the Middle East, Central Asia and China are the main terrestrial sources of airborne dust. It has been argued that poor management of Earth's drylands, such as neglecting the fallow system, are increasing the size and frequency of dust storms from desert margins and changing both the local and global climate, as well as impacting local economies. The term ''sandstorm'' is used most often in the context of desert du ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fast Syndrome Based Hash
In cryptography, the fast syndrome-based hash functions (FSB) are a family of cryptographic hash functions introduced in 2003 by Daniel Augot, Matthieu Finiasz, and Nicolas Sendrier. Unlike most other cryptographic hash functions in use today, FSB can to a certain extent be proven to be secure. More exactly, it can be proven that breaking FSB is at least as difficult as solving a certain NP-complete problem known as regular syndrome decoding so FSB is provably secure. Though it is not known whether NP-complete problems are solvable in polynomial time, it is often assumed that they are not. Several versions of FSB have been proposed, the latest of which was submitted to the SHA-3 cryptography competition but was rejected in the first round. Though all versions of FSB claim provable security, some preliminary versions were eventually broken. The design of the latest version of FSB has however taken this attack into account and remains secure to all currently known attacks. As usu ...

SIMD (hash Function)
SIMD is a cryptographic hash function based on the Merkle–Damgård construction submitted to the NIST hash function competition by Gaëtan Leurent. It is one of fourteen entries to be accepted into round two of the competition, but was not shortlisted for the third and final round. The designer states that the "most important component of SIMD is its message expansion, which is designed to give a high minimal distance". The algorithm's speed is claimed to be 11–13 cycles per byte Encryption software is software that uses cryptography to prevent unauthorized access to digital information.

Fugue (hash Function)
In classical music, a fugue (, from Latin ''fuga'', meaning "flight" or "escape""Fugue, ''n''." ''The Concise Oxford English Dictionary'', eleventh edition, revised, ed. Catherine Soanes and Angus Stevenson (Oxford and New York: Oxford University Press, 2006). ) is a contrapuntal, polyphonic compositional technique in two or more voices, built on a subject (a musical theme) that is introduced at the beginning in imitation (repetition at different pitches), which recurs frequently throughout the course of the composition. It is not to be confused with a '' fuguing tune'', which is a style of song popularized by and mostly limited to early American (i.e. shape note or "Sacred Harp") music and West Gallery music. A fugue usually has three main sections: an exposition, a development, and a final entry that contains the return of the subject in the fugue's tonic key. Fugues can also have episodes, which are parts of the fugue where new material often based on the subject is hea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
France Telecom
Orange S.A. (; formerly , stylised as france telecom) is a French multinational telecommunications corporation founded in 1988 and headquartered in Issy-les-Moulineaux, near Paris. ''Orange'' has been the corporation's main brand for mobile, landline, internet and Internet Protocol television (IPTV) services since 2006. It traces its origins back to Hutchison Whampoa acquiring a controlling stake in Microtel Communications in 1994 in the United Kingdom. Microtel Communications became a subsidiary of Mannesmann in 1999 and then was acquired by ''France Télécom'' in 2000. The former French public telecoms monopoly thus became internationalized following this takeover and has pursued an expansionist policy since. The group now operates in many countries in Europe, Africa and in the French West Indies. Since February 2012, as a result of the company's decision to transfer its fixed-line telephony operations to its ''Orange'' brand, all offers marketed by France Télécom are ' ...

CubeHash
CubeHash is a cryptographic hash function submitted to the NIST hash function competition by Daniel J. Bernstein. CubeHash has a 128 byte state, uses wide pipe construction, and is ARX based. Message blocks are XORed into the initial bits of a 128-byte state, which then goes through an r-round bijective transformation between blocks. The initial NIST proposal ("Cubehash8/1") required about 200 cycles per byte. After clarifications from NIST, the author changed the proposal to Cubehash16/32, which "is approximately 16 times faster than CubeHash8/1, easily catching up to both SHA-256 and SHA-512 on the reference platform" while still maintaining a "comfortable security margin". CubeHash advanced to the second round of the competition, but was not chosen as one of the 5 finalists. According to NIST, it has a "simple, well-understood design" that is suitable for constrained environments. However, performance suffers for short messages when the processor does not have a vector uni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sponge Function
Sponges or sea sponges are primarily marine invertebrates of the animal phylum Porifera (; meaning 'pore bearer'), a basal clade and a sister taxon of the diploblasts. They are sessile filter feeders that are bound to the seabed, and are one of the most ancient members of macrobenthos, with many historical species being important reef-building organisms. Sponges are multicellular organisms consisting of jelly-like mesohyl sandwiched between two thin layers of cells, and usually have tube-like bodies full of pores and channels that allow water to circulate through them. They have unspecialized cells that can transform into other types and that often migrate between the main cell layers and the mesohyl in the process. They do not have complex nervous, digestive or circulatory systems. Instead, most rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes, usually via flagella movements of the so-called " collar ce ...
