A new method for obtaining random bijective S-boxes based on discrete chaotic map is
presented. The proposed method uses a discrete chaotic map based on the composition of …

An S-box is the most important part of a symmetric encryption algorithm. Various schemes
are put forward by using chaos theory. In this paper, a construction method of S-boxes with …

The interesting features of chaos theory are utilized now a day's in information security. The
simplest chaotic dynamical system is the double pendulum. Here in this article, two double …

In a rapidly advancing world of technology, information security studies have become the
backbone of the digital age, and steps in this area are critical. In this context, cryptography …

The increase use of computer and communication system by industry and organizations has
increased the risk of theft of proprietary information. Although these threats require a variety …

This paper proposes to present a novel group theoretic approach of improvising the
cryptographic features of substitution-boxes. The approach employs a proposed finite …

In this article, we will analyze substitution box (S-box) based on residue of prime number for
different analysis such as graphical and analytical strict avalanche criterion (SAC), bit …

There exist several performance criteria for cryptographically-strong substitution boxes (S-
boxes), which are often conflicting with each other. Constructing S-boxes that satisfy multiple …

In this paper, we present a method to construct a substitution box used in encryption
applications. The proposed algorithm for the construction of substitution box relies on the …

The strength of cryptosystems heavily relies on the substitution boxes. Cryptosystems with
weak substitution boxes cannot resist algebraic attacks, linear and differential cryptanalysis …
