Chaos-based encryption is promising for safeguarding digital images. Nonetheless, existing chaos-based algorithms still exhibit certain shortcomings. Given this, we propose a novel multi-channel image algorithm that leverages pixel reorganization and hyperchaotic maps (MIEA-PRHM). Our MIEA-PRHM employs two to jointly generate chaotic sequences, ensuring larger key space better randomness. During the process, first convert input images into fused matrices through reorganization. Then, apply rounds of scrambling diffusion operations, coupled with one round substitution high 4-bit matrix. For low matrix, conduct operations. Extensive experiments comparisons demonstrate outperforms many recent in various aspects, especially efficiency.
