摘要
数字图像置乱加密技术是一种重要的数据加密技术和有效的安全增强手段,对于提高网络信息传输的安全性具有重要意义。该文解析了图像置乱变换的定义、周期和图像置乱程度的衡量方法,阐述了图像置乱加密技术研究进展情况,指出了置乱技术今后将继续研究的方向。
Digital image scrambling transformation is an important data encryption techniques and an effective means to improve security in network communication. In this paper, the definition of digital image scrambling transformation is described, the period and the degree of scrambling transformation are also discussed, some important algorithms are proposed separately, and the future direction in this field is indicated finally.
