An improved image encryption algorithm based on the general cat map
Xuefeng Zhang · 2012
In order to encrypt the digital image with any size,an image encryption algorithm of a combination of the two-dimensional non equilateral image scrambling transformation and logistic chaotic map is proposed.Firstly,it use the two-dimensional non equilateral image scrambling transformation to scramble the image pixels' position,and then use the chaotic sequence generated by the logistic chaotic map with the image pixels' value to do calculations.The experimental results show that the proposed algorithm can get a good encryption,and has the large key space,key sensitivity and many other feathers.
