Abstract:	This paper proposes an image encryption algorithm that integrates an improved four-dimensional hyperchaotic system, compressive sensing, and simulated quantum key distribution technology. Firstly, Arnold scrambling is adopted to preliminarily disrupt the pixel positions of the color image to enhance spatial confusion. Secondly, compressive sensing coding is implemented on the image using a randomly generated measurement matrix to achieve the dual effects of compression and encryption. Finally, the highly random chaotic sequence generated by the hyperchaotic system is combined with the simulated quantum key stream for diffusion encryption. The results show that the entropy generated by our method is as high as 7.999 bits per pixel. Further enhance the sensitivity of keys and the security of algorithms. This method significantly enhances the robustness and anti-attack capability of the system while maintaining the efficiency of image encryption. [ABSTRACT FROM AUTHOR]
