Title:
Spectral Domain Analysis of Correlation Immune and Resilient Boolean Functions

Authors: Palash Sarkar

Abstract:

In this paper we prove a general result on the Walsh Transform
of an arbitrary Boolean function. As a consequence, we obtain several
divisibility results on the Walsh Transform of correlation immune and
resilient Boolean functions. This allows us to improve upper bounds
on the nonlinearity of correlation immune and resilient Boolean
functions. Also we provide new necessary conditions on the algebraic
normal form of correlation immune/resilient functions attaining the
maximum possible nonlinearity.
