Abstract

Discrete memristive chaotic systems play a crucial role in information security, and chaotic synchronization form the bedrock of secure and confidential communication. To enhance the chaotic complexity of the Cubic map, we introduce a memristor-coupled Cubic hyperchaotic system by integrating a discrete absolute memristor model with the Cubic map. The dynamics are thoroughly investigated through attractor phase diagrams, bifurcation diagrams, SE complexity analysis, and diagrams illustrating the distribution of dynamic behaviors. Furthermore, we establish methods for chaos control and nonlinear feedback synchronization for the memristive Cubic map. Leveraging this feedback synchronization, we achieve encrypted transmission of digital images. Simulation results validate the feasibility and robust security of the proposed encrypted transmission scheme.
Memristor 耦合立方超混沌系统、反馈同步及其在图像加密中的应用
离散忆阻器混沌系统在信息安全中起着至关重要的作用,混沌同步是安全保密通信的基石。为了提高立方体图的混沌复杂性,我们通过将离散绝对忆阻器模型与立方体图相结合,引入了忆阻器耦合立方体超混沌系统。我们通过吸引相图、分岔图、SE 复杂性分析和动态行为分布图对动力学进行了深入研究。此外,我们还建立了针对忆阻器立方体图的混沌控制和非线性反馈同步方法。利用这种反馈同步,我们实现了数字图像的加密传输。仿真结果验证了所提加密传输方案的可行性和稳健安全性。
