Arnold 变换与 Gray 码变换相融合的双置乱算法研究
ON DOUBLE SCRAMBLING ALGORITHM INTEGRATING ARNOLD TRANSFORMATION AND GRAY CODE PERMUTATION
摘要
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.关键词
