Shrinking generator — Générateur par rétrécissement En cryptographie, un générateur par rétrécissement (shrinking generator) est un générateur de nombres pseudo aléatoires destiné à un chiffrement de flot. Ce principe a été publié en 1993 par Don Coppersmith, Hugo… … Wikipédia en Français
Self-shrinking generator — A self shrinking generator is a pseudorandom number generator and a variant of the shrinking generator concept. It is a generator used in cryptography and has reasonable security properties when used in conjunction with a Linear feedback shift… … Wikipedia
Alternating step generator — In cryptography, an alternating step generator (ASG) is a cryptographic pseudorandom number generator intended to be used in a stream cipher. The design was published in 1987 by C. G. Günther. It is also known as the alternating stop and go… … Wikipedia
Cryptographically secure pseudorandom number generator — A cryptographically secure pseudo random number generator (CSPRNG) is a pseudo random number generator (PRNG) with properties that make it suitable for use in cryptography. Many aspects of cryptography require random numbers, for example: Key… … Wikipedia
special effects generator — TV (SEG) Video signal processor with vast, but varying, image manipulation capabilitiesinvolving patterns and placement as well as color and texture: mixing, multiplying, shrinking, strobing, wiping, dissolving, flipping, colorizing, etc … Audio and video glossary
Schlüsselstromgenerator — Ein Schlüsselstromgenerator ist der Kernbestandteil einer Stromverschlüsselung. Er erzeugt aus dem Schlüssel den Schlüsselstrom, der auf die Nachricht addiert wird, um sie zu verschlüsseln. Die gängigsten Konstruktionen basieren auf linear… … Deutsch Wikipedia
Stream 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… … Wikipedia
Correlation attack — In cryptography, correlation attacks are a class of known plaintext attacks for breaking stream ciphers whose keystream is generated by combining the output of several linear feedback shift registers (called LFSRs for the rest of this article)… … Wikipedia
FISH (cipher) — For the British code word for World War II German stream cipher teleprinter secure communications devices, see Fish (cryptography). The FISH (FIbonacci SHrinking) stream cipher is a fast software based stream cipher using Lagged Fibonacci… … Wikipedia
