摘　　要：在进行数字图像置乱时,于二维Duffing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Duffing映射加以改进,提出了一种三维Duffing映射。实验结果表明:三维Duffing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抗攻击性。In the digital image scrambling, two-dimensional Duffing mapping usual y only can proceed position scrambling.We need proceed not only position scrambling but pixel values scrambling in this paper.So this paper proposes a three-dimensional Duf ing mapping which is improved on two-dimensional Duffing mapping. The experimental results show that Three-dimensional Duffing mapping can be very wel for digital image scrambling, and the scrambling algorithm has good resistance to attacks.
