Abstract:The rapid advancement of remote sensing technology has heightened concerns over the security of sensitive in-formation. 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 2D plain-image to a 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.
