This paper utilized some characteristics on invariant distribution density and iteration track of a composite discrete chaotic dynamical system which had been presented.Used the R sequence based on the pseudo-randomness of Logistic-map to select iteration function in composite discrete chaotic dynamical system to get a new chaotic sequence.According to the above,prosented a digital image encryption algorithm.In the end,discussed the security of this algorithm.The result of this experiment shows that the encrypted image has high security.
