基于对合矩阵的复合图像加密算法

摘要/Abstract

摘要： 随着互联网在经济社会和国家安全中扮演着越来越重要的角色,近年来,网络数据传输安全引起了学界的重视,其中数字图像信息的加密传输是研究的热点问题之一。传统的图像加密方法形式较为单一,存在一定的漏洞,容易被破解。针对该问题,研究了基于对合矩阵、矩阵分解和信息隐藏的复合加密算法。利用对合矩阵对原始图像进行加密,将加密图像分解成若干低像素值的图像后分别隐藏到公开的信息中。实例说明,此种方法的安全性能较高,效果良好。

关键词: 对合矩阵, 矩阵分解, 图像加密, 信息隐藏

Abstract: As the Internet plays a more and more important role in economic society and national security,the security of network data transmission has attracted the attention of academic circles in recent years.One of the hot research issues is the encryption and transmission of digital image information.The traditional way of image encryption is relatively simple,has some flaws and is easy to be cracked.For this question,the content of the research is a composite encryption algorithm based on involutory matrix,matrix decomposition and information hiding.The original image is encrypted by using the matching matrix,and the encrypted image is decomposed into several low-pixel images and then hidden into the public information.The example shows that this method has high safety performance and good effect.

Key words: Image encryption, Information hiding, Involutory matrix, Matrix decomposition
