摘要

近几十年来，许多研究人员对图像加密与混沌系统的结合进行了研究，并取得了重大进展。提出了一种分数阶记忆混沌系统。通过理论分析和数值模拟，发现该系统具有隐藏吸引子和共存行为。此外，由于混沌系统产生的混沌序列具有密钥空间大、安全性高的特点，提出了一种基于混沌系统的图像加密方案。通过数值仿真验证了本文提出的加密方法的有效性。

A Fractional-Order Chaotic System and its Image Encryption

Many researchers have worked on image encryption combined with chaotic systems, and have made significant progress in recent decades. A fractional-order memristive chaotic systemr is proposed in this paper. Through theoretical analysis and numerical simulation, we found that the system has hidden attractors and coexistence behavior. Other than that, because the chaotic sequence generated by the chaotic system has a large key space and high security, an image encryption scheme is presented based on the chaotic system. We verify the effectiveness of the encryption method proposed in this paper by numerical simulation.
