Summary: This paper introduces a multi-image compression and encryption method based on 3D fractal cube, compressed sensing, and chaos. The plain images are sparsified using the Haar Wavelet Transform and measured using compressed sensing. A four-wing hyperchaotic system is used to generate the measurement matrix. The obtained measurement value matrices are shuffled to reduce the correlation between adjacent pixels, and the cipher images are obtained through adaptive diffusion. Experimental results confirm the satisfactory performance of the algorithm in encryption efficiency, compression performance, and security.
