It is called algebraic attack [5, 14, 17, 18, 15, 25, 27] and has deeply modified the situation with Boolean functions in stream ciphers. Given a Boolean function ... respect to fast algebraic attacks [3, 15, 8]: see [2, 21].

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 … Witryna1 wrz 2024 · Motivated by the impact of fast algebraic attacks on stream ciphers, and recent constructions using a threshold function as main part of the filtering function, we study the fast algebraic immunity of threshold functions. As a first result, we determine exactly the fast algebraic immunity of all majority functions in more than 8 variables. can hives be caused by a virus https://bethesdaautoservices.com

On the fast algebraic immunity of threshold functions

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. WitrynaPrevious reports on fast algebraic attacks [1,5] have underestimated the complexity of substituting the keystream into the system of equations, which in some cases … Witryna197 for the attack in [11]. Moreover, unlike this previous attack, ours does not need generic Gr obner basis algorithms since it only requires to solve a linear system. This … fit hands

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.
