In the internet era, image encryption technology plays a crucial role in ensuring security of information. Aiming at problem that low-dimensional chaotic has relatively small key space and is vulnerable to chosen-plain attacks, this paper proposed novel colour block algorithm based on cellular neural network Chua's system. Firstly, plain separated into three primary colours. And Fourier transform applied achieve optical transformation, generating six sequences iteratively. Secondly, were combined pairs. then with form sequences, which used diffusion process. Finally, improved system scramble image. Both scrambling are performed synchronously during encryption. Through above operation, we get final encrypted picture. The experimental results show excellent effect can resist common attacks.

Abstract To explore the impact of unknown terms and parameters on chaotic characteristics in systems, this paper examines effects state variables parameters. The study focuses different combinations linear, nonlinear, constant It primarily investigates role multi-order their application to system models varying dimensions. Firstly, by simulating a three-dimensional system, analyzes how nonlinear initial conditions affect system's behavior. Secondly, it evaluates four-dimensional combining with parameters, using tools such as Lyapunov index diagrams, sample entropy, dynamic trajectory plots. Finally, integrates constructed mapping develop two-level key image encryption thoroughly assessing its security resistance interference.

Most image encryption methods based on Rubik’s cube scrambling adopt the idea of cyclic shift or map pixels to surface, not fully considering cube’s three-dimensional (3D) properties. In response this defect, we propose a mixed chaotic color method parallel rotation in 3D space. First, seven-dimensional hyperchaotic system is introduced generate pseudo-random integer sequences. Then, proven lemma applied preprocess red (R), green (G), and blue (B) channels plain realize first diffusion. Next, sequence employed control Arnold transformation, scrambled two-dimensional (2D) pixel matrix converted into matrix. by dynamically selecting rotating axis, layer number, angle through sequence. The 2D matrix, realizing second diffusion via exclusive OR with generated logistic mapping. Finally, matrices R, G, B are combined an encrypted image. By performing algorithm reverse, can be decrypted A simulation analysis shows that proposed has larger key space exhibits stronger sensitivity than some existing methods.

To address the consumption and security of color images for transmission storage, a cross-channel image encryption scheme based on discrete memristive coupled neuron model DWT compression is designed in this article. Firstly, dynamics system are analyzed found to possess hyperchaotic phenomenon, which provides sufficient scheme. Secondly, processed by wavelet transform (DWT) has quarter previous capacity. Then, combined with Hash function, resulting sequence given initial value system. Next, particle swarm foraging algorithm (PSFA) better disrupt correlation RGB channel. Finally, complementary DNA coding rule implemented further images. Simulation results show that even lossy compression, recovered can be clearly seen. The performance analysis illustrates under system, proposed brings higher
