摘　　要：在进行数字图像置乱时,于二维Henon映射映射进行图像置乱时,通常只进行位置置乱,本文不仅要进行位置置乱,还要进行像素值置乱,所以对二维Henon映射加以改进,提出了一种三维Henon映射。实验结果表明:三维Henon映射能在很好地进行数字图像置乱,并且该置乱算法具有很好的鲁棒性。In the digital image scrambling, two-dimensional usual y only can proceed position scrambling. We need proceed not only position scrambling but pixel values scrambling in this article. So this paper proposes a three-dimensional Henon mapping which is improved on two-dimensional Henon mapping. The experimental results show that Three-dimensional Henon mapping can be very wel for digital image scrambling, and the scrambling algorithm has good robustness.
