| 摘 要： | 针对单一混沌加密系统对灰度图像进行加密存在加密强度不够、留有轮廓这一问题,给出应用二维Arnold矩阵变换和混沌理论混合加密灰度图像的全新算法,巧妙利用Arnold扰乱图像位置的特点,结合混沌加密理论,有效地解决了单一混沌加密灰度图像加密强度不够的弱点。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。

| Abstract: | Applying the single chaotic encryption system to encrypt the gray image has a problem that you can see the profile of the original picture due to vulnerability in intensity.The novel hybrid gray image encrypt algorithm was given based on 2-dimension arnold matrix transform and chaos theory,applying the Arnold matrix transform to disturb the image pixel together with the chaos theory.Remedy was done to the single chaos theory vulnerability in intensity.This algorithm can be implemented and synchronized easily.The experimental results show that this method can lead to the high security and efficiency. |
