Image Encrypting Algorithm Based on Cascade-Chaotic Mapping

提出了一种应用级联混沌映射对数字图像进行加密的算法.由于混沌映射对初始值和参数的高度敏感性及混沌序列的遍历性和良好的相关性,该算法简单易于实现,且便于同步.实验结果表明,这种加密算法具有高度的安全性和有效性.

In this paper, a new chaotic image encrypting algorithm was proposed based on cascade-chaotic mapping. Because of the high sensitivity to initial value and parameters of the chaotic mapping and the fine ergodicity and correlation, this algorithm can be implemented and synchronized easily. The experimental results show that this algorithm can lead the high security and efficiency.
