Using Inclusion / Exclusion to find Bent and Balanced Monomial Rotation Symmetric Functions
Abstract
There are many cryptographic applications of Boolean functions. Recently, research has been done on monomial rotation symmetric (MRS) functions which have useful cryptographic properties. In this paper we use the inclusion/exclusion principle to construct formulas for the weights of two subclasses of MRS functions: degree d short MRS functions and d-functions. From these results we classify bent and balanced functions of these forms.
