Yunbo Liu · Jisuanji gongcheng · 2012
There are some problems in classical image scrambling algorithms such as needing many iterations,insufficient strength of encryption,little key space and weak resistance.Based on multi-group chaotic sequences and matrix vectorizating operator,this paper proposes a new color digital image scrambling algorithm to solve the problems.By vectorizing and scrambling the RGB matrix of color digital image,the information of original image is hidden.Theory analysis and experiment results show that the new algorithm has large key space and sensitive to the key.It can change the grey-scale feature of image,and scrambling effect is good.
