This file illustrates the nonlinearity of the 4-ary Boolean function Below there are the binary Walsh matrix of order 16 and its complement. The dots in the rows show in which bits they differ from the Boolean function. The lowest and biggest numbers are bold. The lowest number is the Boolean functions nonlinearity, (When the nonlinearity is 0 the function is linear,
This is a Bent function. Its Walsh spectrum is . Its binary Walsh spectrum is the null vector. It belongs to this big equivalence class (top row in matrix number 0), |
