| 摘 要： | 以图像信息安全问题为背景,根据行列式计算的思想,提出了一类新的数字图像置乱加密算法的构造方法,具体构造了两个置乱加密算法,计算出了它们周期,并对图像置乱以后在伪装图像(Stego-image)中的隐藏效果和伪装图像(Stego-image)抗压缩和篡改的免疫性进行了实验分析,表明该类算法中存在一些算法用于图像置乱加密是有应用价值的。

| Abstract: | With the security problem of image information as the background,based on the method of determinant com-puting,a new class construction method for digital image scrambling encryption is presented.Two scrambling encryption algorithms are constructed and their periods are computed.The hiding effects of secret image scrambled in Stego-image and its immunity after Stego-image suffered from compressing,tampering are analyzed.The analytic and experimental re-sults show that there are a few algorithms in this class having potential application in storage and transportation of im-age information for purpose of information security. |
