%X This paper utilized some characteristics on invariant distribution density and iteration track of a composite discrete chaotic dynamical systemwhich had been presented. Used the R sequence based on the pseudo-randomness of Logistic-map to select iteration function in composite discrete chaotic dynamical systemto get a newchaotic 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.
