Aiming at the problems of small key space and weak resistance to differential attacks in
existing encryption algorithms, we proposed a chaotic digital image encryption scheme …

This article presents a unified four-dimensional autonomous chaotic system with various
coexisting attractors. The dynamic behaviors of the system are determined by its special …

This paper introduces a two-dimensional autonomous mega-stable dynamical system with
trigonometric nonlinearities. The nonlinearity of this system is induced by tangent hyperbolic …

The coexistence of different attractors with fixed parameters affords versatility in the
performance of the dynamical system. As a result, recent research has focused on defining …

Non-autonomous conservative system with time-dependent stimulus has rarely been
studied in literature. In this paper, we present a two-dimensional non-autonomous …

Benefiting from trigonometric and hyperbolic functions, a nonlinear megastable chaotic
system is reported in this paper. Its nonlinear equations without linear terms make the …

Here, a chaotic quadratic oscillator with only squared terms is proposed, which shows
various dynamics. The oscillator has eight equilibrium points, and none of them is stable …

This work reports a new family of 5D, 6D, 7D and 8D hyperchaotic systems derived
successively from the 4D hyperchaotic Vaidyanathan system (2018). The new 8D …

This investigation centers on megastable systems, distinguished by their countable infinite
attractors, with a particular emphasis on the Quadratic Megastable Oscillator (QMO). Unlike …

This research delves into the intricate relationship between two fascinating phenomena:
megastability and strange non-chaotic attractors (SNAs). The study centers on a 4D jerk …
