Abstract:

A class of cubic plateaued functions has been investigated. It is shown that they have high nonlinearity without linear structure. A special condition is given that the functions are equivalent to cubic homogenous plateaued functions via the symmetric matrixes. Besides these, a method for constructing cubic homogenous plateaued functions is presented.
