【摘要】 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。更多还原

【Abstract】 A program for image encryption communication based on chaotic maps is implemented. The algorithm in the proposed program can mask the image data and permute pixels location by chaotic sequences. In addition to exact recovery of original signal and high operational peed, this algorithm provides very high security. Illustrative examples are also presented to demonstrate the effectiveness of the algorithm and program.更多还原
