This paper summarizes the symmetric image encryption results of 27 different algorithms,
which include substitution-only, permutation-only or both phases. The cores of these …

A memristive Hopfield neural network (MHNN) with a special activation gradient is proposed
by adding a suitable memristor to the Hopfield neural network (HNN) with a special …

This paper discusses the FPGA implementation of the fractional-order derivative as well as
two fractional-order chaotic systems where one of them has controllable multi-scroll …

In the last three decades a growing interest in develo** nonlinear dynamical systems for

In this paper, a two-wing chaotic system is transformed into a four-wing chaotic system and
an eight-wing chaotic system using fractal processing and the dynamic characteristics of …

In recent years, information security is an increasingly vital problem. In this paper, we
introduce an audio encryption scheme based on the novel digital programmable multi-scroll …

Piecewise linear chaotic map (PWLCM) is a simple chaotic system popularly used for
generating pseudorandom numbers (PRN). Digital implementation of PWLCM degrades the …

After the discovery of the well-known chaotic Lorenz's system, the study of chaos has
