linear feedback shift register
1Linear feedback shift register — (LFSR линейный сдвиговый регистр с обратной связью) один из методов генерации псевдослучайных чисел. Сдвиговый регистр с обратной связью состоит из двух частей: сдвигового регистра и функции обратной связи. Сдвиговый регистр последовательность …
2Linear feedback shift register — [ xor gate provides feedback to the register that shifts bits from left to right. The maximal sequence consists of every possible state except the 0000 state.] A linear feedback shift register (LFSR) is a shift register whose input bit is a… …
3Shift register — In digital circuits a shift register is a group of flip flops set up in a linear fashion which have their inputs and outputs connected together in such a way that the data is shifted down the line when the circuit is activated. Shift registers… …
4Linear rückgekoppeltes Schieberegister — Ein linear rückgekoppeltes Schieberegister (engl. Linear Feedback Shift Register, kurz LFSR) ist ein rückgekoppeltes Schieberegister, das zur Erzeugung von streng deterministischen Pseudozufallszahlenfolgen eingesetzt werden kann. Zur… …

6Maximum length sequence — A maximum length sequence (MLS) is a type of pseudorandom binary sequence. They are bit sequences generated using maximal linear feedback shift registers and are so called because they are periodic and reproduce every binary sequence that can be… …
7Stream cipher — The operation of the keystream generator in A5/1, a LFSR based stream cipher used to encrypt mobile phone conversations. In cryptography, a stream cipher is a symmetric key cipher where plaintext digits are combined with a pseudorandom cipher… …
8Cryptanalysis of TIA's Common Cryptographic Algorithms — In 1992, the TR 45 working group within the Telecommunications Industry Association (TIA) developed a standard for integration of cryptographic technology into tomorrow s digital cellular systems [TIA92] , which has been updated at least once… …
9SOBER — In cryptography, SOBER is a family of stream ciphers initially designed by [http://seer grog.net Greg Rose] of QUALCOMM Australia starting in 1997. The name is a contrived acronym for S eventeen O ctet B yte E nabled R egister. Initially the… …
10Grain (cipher) — Grain is a stream cipher submitted to eSTREAM in 2004 by Martin Hell, Thomas Johansson and Willi Meier. It has been selected for the final eSTREAM portfolio for Profile 2 by the eSTREAM project. Grain is designed primarily for restricted hardware …
