This paper presents a new third-order symmetric difference equation transformed into 3D discrete map. The nonlinear dynamics and symmetry of the proposed map are analyzed with two initial conditions for exploring sensitivity highlighting influence parameters on its behaviors, thus comparing findings. Moreover, stability zero fixed point examined by theoretical analysis, it is proved that generates diverse traits comprising multistability, chaos, hyperchaos, which confirmed phase attractors in 2D space, Lyapunov exponents (LEs) analysis bifurcation diagrams; also, 0-1 test sample entropy (SampEn) used to confirm existence measure complexity chaos. In addition, controller introduced stabilize synchronize duo unified maps. Finally, numerical results provided illustrate

Improved Chua's chaotic system with a novel memristor: Generating multi-scroll hidden attractors and applications in image encryption

Physica Scripta, Год журнала: 2024, Номер 99(10), С. 105253 - 105253

Опубликована: Сен. 3, 2024

Abstract In this paper, a new method for generating multi-scroll chaotic attractors by introducing memristor model into an improved Chua’s system is presented. The dynamic characteristics of the are analyzed, including equilibria and stability, bifurcation diagrams, Lyapunov exponents phase diagrams. Strikingly, it can exhibit three-scroll, four-scroll five-scroll hidden only changing one parameter different shapes coexist with same parameter. Furthermore, high randomness verified through 0–1 test NIST test. By using system, image encryption algorithm (IEA) designed to guarantee secure efficient transmission digital images. This IEA uses whirlpool transformation scramble pixel positions DNA computation diffuse values. simulation performance analysis results indicate that proposed has security reliable performance, which in turn confirms availability memristor-based system.
