Abstract Directed by Shannon’s disorder theory, this paper present a scheme for generating key sequences by using the sensitivity to initial values and the long time unpredictability of chaos motion. The generating scheme and process of the key sequence are described in detail. The size of the key space, randomness testing and linear complexity testing are carefully studied by computer simulation. The results indicate that the key sequences satisfy the requirements of data encrypting.
