| 摘 要： | 总结了改进型Logistic映射的概率分布、均值、自相关和互相关等统计特性。运用MATLAB软件,分别在理想和非理想条件下,对正弦和图像信号进行混沌加解密仿真。调制扰乱了原始Logistic混沌序列,导致几乎不可能从捕获信号中重构出所采用的Logistic混沌系统。要想成功解调必先知道原始初值,然后得出正确序列,否则无法解密成功。

| Abstract: | The paper summarizes the probability distribution,mean,self-correlation and cross-correlation and related statistical characteristics of the improved Logistic map.We simulate in ideal and non-ideal simulation,respectively by using Matlab software.The simulation of chaotic encryption and decryption has done on the sine and the image signal.The modulation has clearly disrupted the original Logistic chaotic sequence,so the captured signal is almost impossible to reconstruct the logistic chaotic system.In order to decrypt successfully,we must first know what the original initial value is,and then inverse operation to arrive at a correct sequence,otherwise cannot be decrypted. |
