WitrynaIn this paper, we first analyse the method of finding algebraic immunity of a Boolean function. Given a Boolean function f on n –variables, we identify a reduced set of homogeneous linear equations by solving which one can decide whether there exist annihilators of f at a specific degree. WitrynaIt is shown that all functions of degree d satisfy a common, function-independent linear combination that may be used in the pre-computation step of the fast algebraic … WitrynaImproving Fast Algebraic Attacks Frederik Armknecht Theoretische Informatik Universit¨at Mannheim, 68131 Mannheim, Germany [email protected] … gold cross band ring

"WitrynaRecently, new kinds of attacks drawn from an original idea of Shannon [15] has emerged; these attacks are called algebraic attacks and fast algebraic attacks [6, 12]. They proceed by modelling the problem of recovering the secret key by means of an over-deﬁned system of multivariate nonlinear equa-tions of algebraic degree at … " - Improving fast algebraic attacks

WitrynaThe (fast) algebraic immunity, including (standard) algebraic immunity and the resistance against fast algebraic attacks, is considered as an important cryptographic property for Boolean functions used in stream ciphers resisting both algebraic and fast algebraic attacks. WitrynaIn this paper we present a construction keeping in mind the basic theory of annihilator immunity. This construction provides functions with the maximum possible …

WitrynaAn improvement on the algebraic attacks called fast algebraic attacks was presented in [7]. These attacks have been further examined in [3,21]. The ﬂrst algebraic attack on a block cipher was discussed in [30]. In [11] Courtois and Pieprzyk showed that AES can be attacked by solving a system of quadratic equations.
