Abstract

In this paper, the main results are concerned with the Walsh transform and the autocorrelation function of select logic functions. Select logic functions with large number of variables have perfect stability and can resist towards cryptanalysis of best affine approximation, but they can't resist towards differential cryptanalysis efficiently because of weak propagation property. By a linear transformation of coordinates, an explicit construction for functions satisfying the strict avalanche criterion or Being correlation immune is provided.
