WitrynaNonlinear invariant attack Attack was introduced by Todo, Leander and Sasaki in 2016. Core idea Considering an n-bit block cipher whose encryption function is E(x;k), look for anon-linear Boolean function g : GF(2)n!GF(2)such that g(x) g(E(x;k)) = constant 8x: We call g a nonlinear invariant for E(x;k), Witrynato study Nrounds, if there is an invariant for 1 or 2 rounds, the game is over. Our approach continues the research on non-linear cryptanalysis of block ci-phers [35,40,16,17] with a speci c twist: we allow the attacker to manipulate the Boolean function Z. There is abundant literature about how a highly-nonlinear
