Abstract

For the low dimensional chaotic system, the key space is small and the security of the encryption system is low. This paper presented an image encryption method for complex chaotic sequences formed by sine chaos changing uniformly distributed logistic chaos order. First, it generated a logistic chaotic sequence obeying uniform distribution, and used sine chaotic sequence to rearrange the repeated part after the integer of the sequence, so that it used the compound chaotic sequence without repeating value for pixel position disorder. After that, because position scrambling alone could change the histogram features of gray statistics of the image, it used sine chaos to rearrange the entire logistic chaos sequence to form compound chaotic sequence, so as to complete image encryption by pixel diffusion. It measured the method security from key space, key sensiti-vity, differential analysis, statistical histogram, adjacent pixel correlation and information entropy. The experimental results show that this method has a large key space and high sensitivity, and can effectively resist exhaustive analysis, differential analysis and statistical analysis.
