“…Chaotic systems that satisfy the major requirements of cryptography properties such as diffusion and confusion are differentiated on the basis of their reactiveness to ergodicity, pseudorandomness, unpredictability, control parameters, and initial conditions; this makes chaotic systems particularly catch heaps of heed for cryptology [1][2][3][4][5]. Due to this matter, chaotic S-boxes have proved to be superior for encrypting a message.…”

As the unique nonlinear component of block ciphers, Substitution box (S-box) directly affects the safety of a cryptographic system. It is important and difficult to design strong S-box that simultaneously meets multiple cryptographic criteria such as bijection, nonlinearity, strict avalanche criterion (SAC), bit independence criterion (BIC), differential probability (DP), and linear probability (LP). Though many chaotic S-boxes have been proposed, the cryptographic performance of most of them needs to be further improved. A new chaotic S-box based on the intertwining logistic map and bacterial foraging optimization is designed in this paper. It firstly iterates the intertwining logistic map to construct many S-boxes and then applies a bacterial foraging optimization algorithm to find the optimal S-box. Moreover, bacterial foraging optimization algorithm considers the nonlinearity and differential uniformity as the fitness functions in the optimization process. We experiment that the proposed S-box can effectively resist multiple types of cryptanalysis attacks.

“…Due to the inherent characteristics of digital images such as high redundancy, bulk data capacity and strong correlation, the traditional image encryption schemes such as Data Encryption Standard, International Data Encryption Algorithm and Advanced Encryption Standard, could not gear the demand of digital image encryption acceptably [17,34]. However, the chaos-based image encryption schemes show brilliant performances due to the intrinsic characteristics of chaotic system, such as sensitiveness to initial condition, non-periodicity, persudo-random property [27].…”

An efficient image encryption scheme is designed based on 2D hyper-chaotic system. Different from the traditional chaos-based image encryption schemes, the confusion and the diffusion procedures of the proposed scheme are interacted on each other. In the encryption process, the position of the present pixel is influenced by the last diffused one. Then the corresponding diffused pixel makes a difference in the next pixel. By contrast with the traditional chaos-based image cryptosystems, the proposed cryptosystem with the interacted structure is steadier and harder to decipher. In addition, 2D hyper-chaotic systems are employed in the quicker generation of chaotic sequences in comparison to high-dimensional hyper-chaotic systems. Simulation results verify the security and effectiveness of this scheme.

In many encryption systems, the original data are transformed into encrypted version by applying nonlinear substitutions and inducing diffusion. The objective of the nonlinear transformation is to attain high levels of randomness in the cipher text. The choice of the source of randomness is critical because the success in cryptanalysis is demarked by the characteristics identified in the encrypted data. The chaotic systems show random behavior that is suitable for encryption applications where nonlinear transformations are required between plaintext and the encrypted data. The application of nonlinear functional chaos-based system with embedded chaotic system and multi-parameters can instigate randomness and diffusion in the data. In addition to high level of randomness, the need for multiple round keys is required in a typical substitutionpermutation process. The proposed method eliminates the need for multiple round keys, which is suitable for high-speed communication systems. The statistical experiments performed on the proposed nonlinear transformation algorithms show improvement in encryption strength and resistance against many brute force and statistical attacks. In addition, the proposed system shows high resistance against differential and linear cryptanalysis.
