Webvision property propagations of any S-box for the given in-put division property, and we summarize the computations in the following lemma. Lemma 1. Let S be an n-bit S-box. Assume that the input division property of S is D1,n k, where k denotes an n-dimensional binary vector. Let u denote an n-dimensional binary vector.
