Algorithm characterizations — The word algorithm does not have a generally accepted definition. Researchers are actively working in formalizing this term. This article will present some of the characterizations of the notion of algorithm in more detail. This article is a… … Wikipedia
Block cipher — In cryptography, a block cipher is a symmetric key cipher operating on fixed length groups of bits, called blocks, with an unvarying transformation. A block cipher encryption algorithm might take (for example) a 128 bit block of plaintext as… … Wikipedia
Block cipher modes of operation — This article is about cryptography. For method of operating , see modus operandi. In cryptography, modes of operation is the procedure of enabling the repeated and secure use of a block cipher under a single key.[1][2] A block cipher by itself… … Wikipedia
NIST hash function competition — Cryptography portal The NIST hash function competition is an open competition held by the US National Institute of Standards and Technology for a new SHA 3 function to replace the older SHA 1 and SHA 2, which was formally announced in the Federal … Wikipedia
Tiny Encryption Algorithm — Infobox block cipher name = TEA caption = Two Feistel rounds (one cycle) of TEA designers = Roger Needham, David Wheeler publish date = 1994 derived from = derived to = XTEA key size = 128 bits block size = 64 bits structure = Feistel network… … Wikipedia
Cryptographic hash function — A cryptographic hash function (specifically, SHA 1) at work. Note that even small changes in the source input (here in the word over ) drastically change the resulting output, by the so called avalanche effect. A cryptographic hash function is a… … Wikipedia
Genetic algorithm — A genetic algorithm (GA) is a search heuristic that mimics the process of natural evolution. This heuristic is routinely used to generate useful solutions to optimization and search problems. Genetic algorithms belong to the larger class of… … Wikipedia
One-way compression function — In cryptography, a one way compression function is a function that transforms two fixed length inputs to an output of the same size as one of the inputs. The transformation is one way , meaning that it is difficult given a particular output to… … Wikipedia
Selection algorithm — In computer science, a selection algorithm is an algorithm for finding the kth smallest number in a list (such a number is called the kth order statistic). This includes the cases of finding the minimum, maximum, and median elements. There are… … Wikipedia
GOST (block cipher) — Infobox block cipher name = GOST 28147 89 caption = Diagram of GOST designers = USSR publish date = 1994 (declassified) derived from = derived to = key size = 256 bits block size = 64 bits structure = Feistel network rounds = 32 cryptanalysis =… … Wikipedia
Divide-and-conquer eigenvalue algorithm — Divide and conquer eigenvalue algorithms are a class of eigenvalue algorithms for Hermitian or real symmetric matrices that have recently (circa 1990s) become competitive in terms of stability and efficiency with more traditional algorithms such… … Wikipedia
