摘要
利用一个幂余函数f(x)=(axk)(mod m)或多个幂余函数的积函数的单调性来对数字图像进行像素位置的置乱加密,这种加密生成结果也称为幂余多参数码。本文阐述了单个幂余函数与多个幂余函数的积进行多密钥图像加密的方法及结果,并进行耗时对比。
This paper proposed a novel approach of encryption for digital image using a power-remainder function (f(x) = (axk) (rood m) )or many power-remainder functions. The result of encryption is named the power-remain- der multi-parameter code. There are several mathematical principles in the eneryption for digital image, in which the process and the evaluation in this way are showed.
