%X Concerning the degeneracy of the computer limited precision effect in a single one-dimensional discrete chaotic system,this article proposed a method of pseudo-random sequence generation with variable parameters in the process of the generation of the chaotic signal.The constructed chaos system based on this method had some advantages,such as the long cycle of pseudo-random sequence,the large quantity of key and the big superiority of key space,and the prodeced password has a higher safety performance.Besid...
