1. One important property which makes DES secure is that the S-boxes are non-linear. In this problem we are going to verify this property by computing the output of S1 for several pairs of inputs. Show that S1(x1) ? S1(x2) 6= S1(x1 ? x2), where ? denotes bitwise XOR, for: x1 = 000000, x2 = 000001 x1 = 111111, x2 = 100000
