Chaotic Map-Based Image Encryption Scheme with Modified SPN Architecture

This paper presents a novel image encryption scheme that aims to enhance encryption security while maintaining efficiency by integrating dynamic S-boxes, SPN (Substitution-Permutation Network) structure, and chaos encryption technol-ogy. This integrated approach not only harnesses the potential of chaos theory in enhancing cryptographic security but also takes into account computational constraints in practical applications, with the goal of improving the robustness and practicality of the overall security architecture.
