基于三维分割的图像加密算法

为了实现图像安全、快速加密,设计了一种新的数字图像混沌加密算法.仿真结果表明,该算法在没有扩散函数的情况下也能很好地改变图像的直方图,可以有效地抵制已知(选择)明文攻击,而且只有1次左映射或者右映射的情况下,该方法具有高置乱程度、良好的扩散性能和足够大的密钥空间,可获得足够高的安全性.

Image encryption based on the segmentation of three-dimensional space

In order to satisfy the need of security and speed of image eneryption, this paper proposes a novel chaotic eneryption about digital image. The simulation results show that ,without the diffusion-algorithm, it can change the histogram of image and resist the plain-text attack very well. Furthermore, even though you just only use once left map or once right map, this algorithm has high confusion , good diffusion, large enough key space and high secure.
