| 摘 要： | 图像置乱是图像加密的常用方法,为了获得更好的加密效果,提出了一种基于分数阶小波变换(FWT)的图像加密新方法。该方法将二维分数阶小波变换与传统的空间域图像置乱方法相结合,对数字图像在分数阶小波时频域内进行图像置乱,实现图像的双重加密。图像加密实验结果表明,采用该方法具有很好的加密效果,在信息安全领域有较好的应用前景和研究价值。

| Abstract: | The picture scrambling algorithms are frequently used for images secure communications. In order to improve the effect in image encryption, a novel image encryption method is proposed in this paper. This technology is based on fractional wavelet transform(FWT) and image scrambling algorithms. The experiment results show that the technology performs considerable security, which has well research value and application foreground in the information security field. |
