Abstract: The dulity of Plateaued functions was analyzed.Based on the definition and the restriction of Plateaued functions on some affine subspaces,we proved that there are strong relationships between a Plateaued function and its dulity,especially on the restriction on flats.We also derived the bound of the sum-of-squares indicator of the cross-correlation between any two Plateaued functions by using the tool of dulity.

Key words: Plateaued functions,Dulity,Normality,Bent functions
