“…For an encryption algorithm, key sensitivity is one of the important evaluation criteria, that is, a small change in the key can cause sufficient changes in the ciphertext. From a statistical point of view, the rate of change of the ciphertext must close to 50% [11]. The Diffractive Encryption proposed in this paper, the intuitive embodiment of the change of the ciphertext, is the change of the result of each operation.…”

In this paper, we propose a brand-new chaotic encryption model that defines operations based on the data, which named Diffractive Encryption. We take a specific encryption algorithm as an example to prove the excellent effect and high security of the model. Unlike the existing encryption methods, the ciphertext generated by our encryption model hardly carries any data-related information, i.e. the plaintext does not directly participate in the encryption operation to form the ciphertext. Finally, we make a more objective security analysis of the encryption algorithm in this paper with the perspective of traditional security analysis. In the field of Chaotic Cryptography, this is a disruptive idea, and may become a new research direction.

“…Except for the first time, the average bit-change rate of ciphertext in last 8 times is calculated. The change rate of initial values and parameters of chaotic map is 10 −15 , which can fully deal with Brute-Force Attack [11]. The bit-change rate of each file is shown in Table 2.…”

In the past few decades, the transmission of data over an unsecure channel has resulted in an increased rate of hacking. The requirement to make multimedia data more secure is increasing day by day. Numerous algorithms have been developed to improve efficiency and robustness in the encryption process. In this article, a novel and secure image encryption algorithm is presented. It is based on a modified chaotic logistic map (CLM) that provides the advantage of taking less computational time to encrypt an input image. The encryption algorithm is based on Shannon’s idea of using a substitution–permutation and one-time pad network to achieve ideal secrecy. The CLM is used for substitution and permutation to improve randomness and increase dependency on the encryption key. Various statistical tests are conducted, such as keyspace analysis, complexity analysis, sensitivity analysis, strict avalanche criteria (SAC), histogram analysis, entropy analysis, mean of absolute deviation (MAD) analysis, correlation analysis, contrast analysis and homogeneity, to give a comparative analysis of the proposed algorithm and verify its security. As a result of various statistical tests, it is evident that the proposed algorithm is more efficient and robust as compared to previous ones.

“…The length of the security key controls the size of the key space and which is one of the most key characteristics to estimate the strength of the cryptosystem against brute force attacks [63]. To prevent this attack, the size of key space must be at least 2 100 [64].…”

This work proposes a physical memristor (TaOx) based new 4D chaotic system with 3D multi-scroll, no equilibrium point, spiking behaviour, coexistence bursting oscillation and multistability. Using this physical memristor-based chaotic system, a novel and efficient colour image encryption algorithm has been developed using a unique box scrambling method and bit-wise XOR operations. Many interesting and new dynamics of a material-based memristive chaotic system are reported here, like 3D multi-scroll chaotic attractors, bursting characteristics, multistability, a neuronal system like spiking behaviours etc using Lyapunov spectrum and bifurcation plots. It is observed that the number of scrolls is changed with the total simulation time. This novel memristive chaotic system has limit cycles with controllable spikes and bursting oscillation. In addition, the system shows chaotic bursting oscillation under a different set of parameters and initial conditions. The coexistence of the bursting phenomena is studied here. The bursting and spiking characteristic is important for material-based memristors in neuromorphic applications. 3D Chaotic multi-scroll and multistability properties make the image encryption method more efficient and secure. Such characteristics are rare in physical memristor-based chaotic systems and using this, the image encryption algorithm is also rare in recent findings. Therefore, a new secure image encryption algorithm for colour images is proposed here, based on the unique box scrambling method, bitwise XOR operation and pseudo-random number generation using the proposed memristive chaotic system. Various tests like NPCR, UACI, histogram analysis, correlation study, information entropy analysis, robustness against external noise, etc have been performed to check the algorithm’s robustness and efficiency and test the capability to resist statistical and differential attacks.
