Research on an intelligent encryption method for remote sensing images with variable dimension employing dual-chaotic system

Abstract

The rapid advancement of remote sensing technology has heightened concerns over the security of sensitive information. This paper presents an intelligent encryption scheme for remote sensing images using dimensionality variation. The scheme employs two high-dimensional chaotic systems to generate keys for simultaneous row-column scrambling and diffusion. By mapping a two-dimensional (2D) plain-image to a three-dimensional (3D) space, pixels are rearranged within a 3D cube using a chaotic key, followed by auto-correlation cyclic diffusion. Experimental results demonstrate that this approach significantly enhances encryption security, making it suitable for secure remote sensing image communication.
