摘要
为了提高Arnold变换图像加密或Arnold变换图像水印算法的执行效率,对Arnold变换的三种恢复方法进行效率分析。以256×256的灰度图像加密为例,对其进行仿真研究。分析三种恢复方法与迭代次数、变换周期的关系,从而得出三种恢复方法的适用场合。这一研究结果将有助于Arnold变换在信息安全方面的应用研究。
In order to improve the efficiency of the Arnold transform image encryption or Arnold transform image watermarking algorithm, the efficiency of the Arnold transform three recovery methods was analyzed. Take gray image encryption as an example, carried on the simulation research. The relationship between the recovery method, the iteration number and the transformation period was analyzed, so as to obtain the application occasions of the three recovery methods. The results of this study will be helpful to the application of Arnold transform in information security.
