提出了一种基于混沌映射的图像保密通信系统的软件实现。算法程序首次采用了图像数据的混沌掩盖加密和图像象素位置的置乱加密相结合的方法,对图像进行了两次复合的混沌加密。它具有恢复精度高、保密度高、破译难度大、执行速度快的特点。文中给出示例显示了算法程序的有效性。
A software implementation of image security communication system based on chaos mapping is proposed. For the first time, the algorithm uses a combination of chaos masking encryption of image data and scrambled encryption of image pixel positions, and the image is chaotic encrypted twice. It has high recovery accuracy, high security, crack difficult, fast execution. The examples given in the paper show the effectiveness of the algorithm.
