A new image encryption algorithm
Chen Gang, Feng Zhi-gang · Journal of Jiangsu University · 2004
By using natural enumerative system a one-to-one mapping is constructed between integer and permutation. Based on this and by using chaotic sequence to select permutation randomly to swap bits of byte of every pixel, different scan patterns in the scan tree structure are selected. Some experimentations are carried out to illustrate the good performance of the proposed method.
