| Abstract: | In this paper,an image-scrambling algorithm based on mixed chaotic sequences is proposed.Firstly,a mixed chaotic sequence is generated with the given key,secondly,it is dispersed into offset matrix and permutation matrix by discrete mapping.Finally,wavelet transform is carried on the image and the image is scrambled in transform domain.The experiment results show that the algorithm has good scrambling character and good encrypting effect is achieved. |
