| 摘 要： | 本文提出了一种新的置乱度定义，该定义能较明确地衡量置乱图像的均匀与细密程度，并使用它柬衡量本文中的置乱实验的效果；提出了一种基于初等函数变换的图像置乱新方法，具有易于实现、复杂性低、密钥空间大、只需一次运算即可达到很好的置乱效果等特点．

| Abstract: | A novel definition of scrambling degree is presented at length,it can better discribe the uniformity and compaction of scrambling image and was used to weigh the effect of scrambling method mentioned.Based on the primary function transform,this paper has brought forward a new way of image scrambling,which is easy to carry out,and the space of key is very large,it needs only one operation instead of more times to reach good scrambling effect. |
