文章摘要
Arnold置乱由于其简单易懂被应用到数字水印、安全防伪、军事机密等各个领域,并得到了很好的效果。Gray码变换由于其在彩色空间和位置空间都能灵活运用等特点在信息安全中也得到了很好实际应用。但是,由于两种算法相对简单,很容易被入侵者破解,为了提高信息的加密程度和抗攻击性,提出一种Arnold与Gray码变换相融合的双置乱算法,使得加密信息在位置空间和灰度空间上都得到很好的隐藏。实验结果表明,该方法能很好地应用在图像处理方面,为信息隐蔽技术的预处理工作提供更好的保证。
Abstract
Arnold scrambling, due to its ease of understanding, has been widely applied in the fields of digital watermarking, security and anti-counterfeiting, military encryption, etc., and achieves good effect. Gray code permutation algorithm has also been well applied in information security, since it can be flexibly implemented in both the colour space and the position space. However, either of them is easily cracked by the intruders, for they are relatively simple. In order to improve the degree of information encryption and anti-attack property, we proposed a double scrambling scheme, it is essentially a combination of the Arnold scrambling and the Gray code permutation algorithm, and makes the encrypted information be well hidden in both the position space and the grey space. Experimental results showed that this new scheme could be well applied in image processing as a better preprocessor for information hiding techniques.
