论文摘要
本文研究和分析了二维行李图的动力学。从系统上观察到了多稳定性行为。这种行为，尤其是混乱和周期性吸引子的共存，在基于混乱的密码学的应用中是不希望的。因此，我们设计并实施了正弦肌动物混乱技术，以增强多稳定区域的混乱。此外，本文提出了一种新的图像加密算法，以检查加密应用中广义行驶图的性能。仿真结果和安全性分析表明，所提出的算法可以有效地对具有高度安全性的几种图像类型进行加密和解密。
This paper investigates and analyzes the dynamics of the two-dimensional Duffing map. Multistability behavior has been observed from the system numerically. Such behavior, especially the coexistence of chaotic and periodic attractors, is undesirable in the applications of chaos-based cryptography. Therefore, we design and implement a Sine-Cosine chaotification technique to enhance chaos in the multistable regions. Furthermore, this paper proposes a new image encryption algorithm to examine the performance of the generalized Duffing map in cryptography applications. Simulation results and security analysis reveal that the proposed algorithm can effectively encrypt and decrypt several image types with a high level of security.
