“…Zhuang et al [17] used QR decomposition and LU decomposition to decompose the hyperchaotic sequences generated iteratively by the constructed five-dimensional multi-looped multi-winged hyperchaotic system into matrices and then applied them to the encryption algorithm. Recently, a memristor-based chaotic system has been widely used in image encryption algorithms due to its complex dynamical behaviors [22][23][24][25][26][27][28].…”

Compared with ordinary chaotic systems, memristor-based chaotic systems have more complex dynamic behaviors and are more suitable for image encryption algorithms. In this paper, a four-dimensional chaotic system is constructed by introducing a cubic nonlinear memristor into a three-dimensional chaotic system. Firstly, the dynamic characteristics of the constructed memristor-based chaotic system are analyzed in detail, and the simulation results show that the system has different attractors with different topological structures at different simulation times. Within a fixed simulation time, the system has 15 attractors with different topological structures under different parameter values, and there is a phenomenon of multiple stability in the system, indicating high complexity. Based on the above discoveries, a color image encryption algorithm including scrambling and diffusion is designed. Experimental results show that this algorithm can perfectly hide the information of the plaintext image, and the decrypted image is consistent with the plaintext image. Finally, the security of the algorithm is analyzed by using key space and so on. The analysis results indicate that the encryption algorithm designed in this paper can effectively resist external attacks and has high security.

“…Since the concept of memristor was put forward by Professor Chua [7] in 1971 to the successful development of physical memristor by HP Labs [8] in 2008, memristor has been put into use in many areas like chaotic circuit [9][10][11][12], image processing [13][14][15][16][17], neural network [18][19][20][21][22][23] and non-volatile memory [24][25][26][27], etc And its bionic function provides a new idea for the study of neurodynamics. The use of memristor to describe the effect of electromagnetic induction on neuronal system can reveal the firing pattern transition and bifurcating mechanism of neuronal system under electromagnetic action [28][29][30][31].…”

A novel bistable locally active memristor is proposed in this paper. A locally active memristive autapse Morris-Lecar neuron model is constructed by using memristor to simulate the autapse of neuron. The equilibrium point and stability of the system are analyzed, and the firing mode and bifurcation characteristics of the neuronal system are revealed by using dynamic analysis methods such as slow-fastdynamics, interspike interval bifurcation diagrams, Lyapunov exponents, phase diagrams and time series diagram. By changing the memristive autapse gain and the initial state of the system, the existence of coexisting firing patterns in the constructed neuron model is confirmed. Finally, to further verify the effectiveness of the numerical simulation, the analog equivalent circuit of the locally active memristive neuron system is designed, which proves that the system is physically realizable.

“…Q. Zhang et al described a way for encrypting images using DNA-XOR processes (Zhang and Wei, 2013). An image encryption application is proposed for a chaotic system based on memristors by Zhang et al (Zhang et al, 2022). Combining the DNA algorithm with an image encoding algorithm, the new system is used to encode the chaotic sequence images, and the results are presented.…”

With the advancement of technology, the growth of multimedia and communication tools has sped up data transfer, and guaranteeing image security has become a crucial concern, particularly during the transmission and storage of images. So, when images are sent over a public network, they should be encrypted before being sent to the receiving part. In this study, a memristor-based encryption system with Deoxyribonucleic acid (DNA) coding is proposed on the LabVIEW platform to ensure information security. Firstly, memrsitor based hyperchaotic system is used for chaotic sequence. The images are encrypted using the DNA and XOR arithmetic process on the LabVIEW platform. A memristor-based hyperchaotic system and the combination of techniques used are aimed at encrypting the image securely. In addition, security tests; histogram analysis, correlation analysis, differential attack, and entropy analysis, are performed on the proposed system and the results are presented. The aforementioned methods are thoroughly examined and tested to determine their efficacy. It has been determined that the proposed encryption schemes are effective and can therefore be used in real-time applications.
