中文摘要：
提出了一种新的混沌彩色图像加密算法.首先由Logistic和Cubic-Henon复合混沌映射生成混沌序列,再结合像素值替代和图像位置置乱方法对彩色图像进行加密,并利用＂一幅图像一次密钥＂的密钥同步方案,实现了一个基于混沌的图像保密通信系统.该算法具有一定的有效性和良好的加密性能.
英文摘要：
A new chaotic color image encryption algorithm is presented with the perfect properties of chaotic sequences.At first,the chaotic sequences are generated of Logistic and Cubic-Henon compound chaotic maps.Then the color image is encrypted combining the methods of pixel value substituting and position shuffling.And the image secure communication system based on chaos is designed and implemented,using key synchronization scheme of ＂ond image with one key＂.The results of system testing show that the algorithm is valid and has good performance.
