分数阶混沌系统电路设计及在保密通信中的应用

The Fractional Order Chaotic System Circuit Design and Its Application in Secure Communication

构建一个三维混沌系统,通过对系统非线性动力学特性进行分析,确定了其混沌吸引子的存在。利用分数阶电路进行了不同分数阶值组合电路的仿真实验,验证了该混沌系统在物理上的可实现性。选择一个异元混沌系统对图像和音频做加密解密实验,证实了该系统具有良好的保密性。

A three-dimensional chaotic system was constructed. The dynamic properties of the new system were investigated, which shows that there exists chaotic attractor. Simulations of the combinational circuits with different fractional order were designed. It demonstrates that the new fractional-order chaotic system can be implemented in the physical. Select a different element of chaos encryption and decryption system to do experiments on the image and audio, the results prove that the system has a good security.
