WitrynaThis improvement of an idea due to C. ... uses the existence of low degree multiples of the nonlinear function. 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].
Improving Fast Algebraic Attacks - CORE Reader
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
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
