本文设计了一种新型的七阶混合记忆混沌电路，并建立了系统的数学模型。计算原点作为唯一的平衡点。基于忆阻混沌电路系统生成的混沌密钥，设计了新的图像加密算法。特别地，利用灰度直方图、相关性和鲁棒性等安全分析方法，分析了新加密算法的安全特性。结果表明，基于该混合记忆性混沌系统的加密算法具有较高的安全性和较好的抗解码能力。与简单的忆阻混沌电路模型相比，该模型具有完整的RLC结构和多个忆阻器。它更接近实际的忆阻混沌电路。因此，对记忆电路的商业化实现具有重要意义。特别是记忆性混沌系统，也为相关领域的研究提供了一个有价值的系统模型。
In this paper, a new seventh-order mixed memristive chaotic circuit was designed, and the new mathematical model of the system was established. The origin as the only equilibrium point was calculated. Based on the chaotic secret key generated by the memristive chaotic circuit system, the new algorithm of the image encryption was designed. In particular, by using the security analysis methods of gray histogram, correlation and robustness, the security feature of the new encryption algorithm was analyzed. And the results show that the encryption algorithm based on this mixed memristive chaotic system has higher security and better anti-decoding ability. In comparison with the simple model of the memristive chaotic circuit, this new memristive chaotic circuit model has complete RLC structure and multiple memristors. It is closer to the actual memristive chaotic circuit. Thus, it is of great significance to the commercial realization of the memristive circuit. In particular, the memristive chaotic system also provides a valuable model of the system for the research of the related fields.
