摘要
Arnold变换具有周期性,广泛应用于图像加密方面,其正变换具有规范的表达式,但Arnold的反变换却没有一个规范表达式,因此论文提出一种Arnold反变换的规范表达式对各类Arnold正反变换进行形式上的统一,规整而简洁化,并在多维上进行推广。
The periodicity of the Arnold transformation is widely used in image encryption aspect. This transformation is provided with normative expression, but its inverse transformation does not. In this paper, a new normative expression which enable all kinds of Arnold transformation and its inverse transformation formally unify is proposed, in good order and concise, and extend it on multidimensional space as well.
