What is Linear cryptanalysis?
In [[cryptography]], '''linear cryptanalysis''' is a general form of [[cryptanalysis]] based on finding [[Affine transformation|affine]] approximations to the action of a [[cipher]]. Attacks have been developed for [[block cipher]]s and [[stream cipher]]s. Linear cryptanalysis is one of the two most widely used attacks on block ciphers; the other being [[differential cryptanalysis]]. A variety of refinements to the attack have been suggested, including using multiple [[Linear approximation|linear approximations]] or including [[Nonlinear system|non-linear]] expressions. Evidence of security against linear cryptanalysis is usually expected of new cipher designs. ==Related pages== * [[Differential cryptanalysis]] {{math-stub}} [[Category:Cryptography]]
