Improved image scrambling algorithm of Arnold Cat transformation
Honge Ren · Computer Engineering and Applications Journal · 2009
Arnold Cat transformation is a classical algorithm of image scrambling.However,it has some disadvantages,such as small key quantities and not better visual effect.At the same time,it only changes the position of pixel point and the pixel value is fixed.So,the attacker may break down it through the statistics.Aimming at the disadvantages,an improved scrambling algorithmm of Arnold Cat transformation using chaotic map is put forward.The experiment results show that the key quantities and scrambling effect are improved obviously,and the security of image encryption is increased.
