Abstract

 Rotation-symmetric Boolean functions (RSBF) that are invariant under circular translation of
indices have been used as components of different cryptosystems. This paper investigates enumeration of the
balanced RSBFs. Based on some improvements and analysis of the solutions of the correlative equation system,
the lower bound on the number of pr-variable balanced RSBFs is improved, where p is a prime. For a general
odd number n, a lower bound on the number of n-variable balanced RSBFs is provided.
