Abstract: Three classes of vectorial Boolean functions are considered such that each of their coordinate functions essentially depends on a given number of variables. The experimental results for the cryptographic properties (algebraic degree, algebraic immunity, nonlinearity, differential uniformity) of compositions of functions from these classes are presented.

Keywords: vectorial Boolean functions, nonlinearity, algebraic immunity, differential uniformity.
