Abstract :

This paper presents an enhanced chaotic AES encryption algorithm with a diffusion mechanism for secure image encryption. The approach combines a dynamically generated chaotic S-box, derived from a logistic map, with a key-dependent diffusion phase to strengthen encryption performance. The chaotic S-box ensures high non-linearity, while the diffusion process introduces randomness and resistance to statistical attacks. Experimental results demonstrate the effectiveness of the proposed method, achieving high entropy values (7.9974), significantly low correlation coefficients (0.0021), and successful decryption with no data loss. These results validate the algorithm's robustness, reliability, and applicability in secure image transmission. Potential applications include sensitive fields such as medical imaging, defense, and IoT. The proposed scheme highlights the synergy between chaos theory and cryptographic techniques, offering a promising direction for future research in advanced encryption mechanism.
