Abstract :
Taking advantage of the typical properties of any chaotic system: ergodicity and pseudo-random, some chaotic block cryptosystems had been put forward by searching through chaotic state space. But the serious defect existing in these cryptosystems is that searching takes too long time. A chaotic block cryptosystem by searching through chaotic state space with the controls parameter transforming module and the state variable transforming module was developed. The analysis shows this cryptosystem reduces the searching time and enhance security.
