This paper aims to develop an image encryption method based on the S-Box concept of advanced encryption standard (AES) and the application of chaotic system. Variable elements of the chaotic system initially generate chaotic-sub-box (CSB) and chaotic-sub-pathway (CSP) matrices, which then substitute the pixels of the original image. Map and gray-level values between the original and encrypted images indicate no interrelation after substitution, so decryption of bits, pixels, and keys even by exhaustive attack is prevented. Practical application shows that the encrypted image has 100% pixel substitution, and no image distortion occurs after image decryption. Therefore, the proposed encryption method is secure, reliable, and feasible.
