Chaotic Image Encryption Based on an Improved Seven-Dimensional Memristor-based Restricted Four-Body System

With the widespread use of digital images in information systems, protecting sensitive visual data has become increasingly crucial. This study develops an improved memristor-restricted four-star seven-dimensional chaotic system based on the constrained N-body problem. Dynamics simulations demonstrate that the system exhibits satisfactory chaotic characteristics. Building upon this system, we propose a novel image encryption scheme. Numerical simulation results demonstrate that proposed encryption scheme can effectively encrypt the image while maintaining robust defense capabilities against external violent attacks.
