Recent research shows that the class of Rotation Symmetric Boolean Functions (RSBFs), ie,
the class of Boolean functions that are invariant under circular translation of indices, is …

The design of Boolean functions with properties of cryptographic significance is a hard task.
In this paper, we adopt an unorthodox approach to the design of such functions. Our search …

In this paper we analyze the combinatorial properties related to the Walsh spectra of rotation
symmetric Boolean functions on even number of variables. These results are then applied in …

The existence of 9-variable Boolean functions having nonlinearity strictly greater than 240
has been shown very recently (May 2006) by Kavut, Maitra and Yücel; a few functions with …

Recently, 9-variable Boolean functions having nonlinearity 241, which is strictly greater than
the bent concatenation bound of 240, have been discovered in the class of Rotation …

Construction and enumeration of the class of balanced rotation symmetric Boolean functions
are important research areas in cryptography. The counting results of this class of functions …

In this paper, we provide an bijective rotation symmetric S-box (RSSB) construction with
improved resistance to differential power analysis (DPA) using rotation-symmetric Boolean …
