| 摘 要： | 分析了logistic映射的稳定点随参数变化的特性及其混沌特征,将logistic映射产生的混沌序列应用于图像加密/解密之中.设计的算法采用了两种不同表达方式的logistic映射所产生的两列混沌序列对图像进行加密.基于这种算法的混沌加密系统具有双参数,对初值极端敏感和不可预测性等优点.计算机仿真实验结果也表明了这种系统具有良好的安全性.

| Abstract: | This paper analyses both the movement of the fixed points with the trend of the parameter and the character of the chaos.The logistic mapping chaos digital-flow is used on the field of encryption and decipher for images.The image is encrypted with chaos algorithms that use two different chaos digital-flows generated by logistic mapping.There are two parameters in this kind of chaos system,and it is sensible to the original value and unpredictable.The good security is also showed by computer simulation. |
