摘要:
提出基于随机区域移位和随机像素映射的图像加密算法.该算法首先对待加密图像进行分割,然后将分割出来的图像单元顺序随机打乱,扰乱了图像的原始信息;然后再对每个图像单元进行像素映射扰乱,切断了各个单元像素值之间的联系.该算法结合了区域移位算法和像素映射算法的优点.计算机模拟表明该算法自由度大、保密性强,对二值图像和灰度图像加密都取得了很好的效果.
Abstract:
Based on reg ion sh ifting encoding and p ixe lm apping, the pape r proposes im ag e encryption algor ithm. The image to be encrypted is div ided into several un its, and the positions of these un its are changed random ly. Then each unit is d isturbed by the p ixe lm apping, cutting the relations between the values of pix els in every un it. The a lgo rithm is based on the v irtues of the reg ion sh ifting and p ixe l mapp ing. The results o f computer simu la tion show that th is m ethod is flex ible in the freedom and strong in secrecy, especia lly for the binary im ag es and gray scale im ag es
