"WitrynaThe core idea of the nonlinear invariant attack is to detect a nonlinear Boolean function gsuch that g(F(x k)) = g(x k) c= g(x) g(k) c 8x for many keys k, where cis a constant in F 2. Keys for which this equality holds will be called weak keys. The function gitself is called nonlinear invariant in this paper. " - Improved nonlinear invariant attack
