“…Ensuring that these images remain confidential during transmission, safeguarding against theft or leakage has become a prominent research focus. 4 , 5 , 6 However, due to the distinctiveness of digital images, 7 , 8 , 9 such as high correlation of adjacent pixel points, scattering distribution of critical information, and high information redundancy, cryptographic protection using traditional text encryption algorithms struggles to meet real-time performance requirements. Furthermore, chaos itself exhibits inherent qualities 10 , 11 , 12 , 13 such as high sensitivity to initial conditions and control parameters, excellent pseudo-randomness, ergodicity, and long-term unpredictability of orbits, and it has many similarities with confusion, diffusion, and so on in cryptography.…”

The principal constituent of a block cipher in symmetric key cryptography is the Boolean function, determining the substitution box (S-box). Block ciphers rely totally on Sboxes with excellent nonlinearity and upright cryptographic structures. In AES, an 8 × 8 S-box is a 16 × 16 look-up table over the Galois field GF(2 8 ), that occupies 8 × 2 8 bytes storage of computer memory. By using traditional method to construct a 24 × 24 S-box over Galois field GF(2 24 ), which lodges a storage memory of 24 × 2 24 bytes in traditional sense. Thus the memory storage does not support a 24 × 24 S-box over a very larger order Galois field like GF(2 24 ). A resolute of this difficulty is possibly coming out from the algebraic structure of the commutative finite chain ring. In this study a subgroup of the multiplicative group of units of the chain ringis considered to construct a 24 × 24 S-box that occupy just 24 × 2 8 bits storage memory of computer. The proposed S-box has a substantial potential to create confusion during substitution phase of the color image enciphering algorithm. While, for the permutation component of the algorithm, DNA transform is applied for creating diffusion in the pixels of the color image. The proposed RGB image encryption attains the standard optimum level when compared it to the DNA and chaos-based image encryption techniques.
