Multi-Images Encryption Scheme Based on 3D Chaotic Map and Substitution Box

The protection of digital content is increasingly becoming a significant issue for researchers and engineers. In this context, nonlinear dynamic systems play vital role in information security through their chaotic behavior susceptibility to initial conditions. This research presents 3D map-based symmetric algorithm multiple images improve encryption efficiency encourage secure transmission. proposed scheme comprises the following four modules: combination (the are combined into single image by merging color channels); permutation (using suggested map); S-box generation; substitution AES method. algorithm's strength was determined Entropy, Correlation coefficient, NPCR, UACI analyses, which were then compared past techniques. Furthermore, method assessed terms its computation time. Results demonstrate that it highly efficient real-time communication.
