| 摘 要： | 针对单混沌系统因计算机有限精度效应产生的混沌退化问题,提出了一种多级混沌映射变参数伪随机序列产生方法,基于该方法构建的混沌系统较单混沌系统具有伪随机序列周期大,密钥数量多,密钥空间大等优势,所产生的密码具有更高的安全性能.仿真结果表明,该方法在低复杂度条件下可以生成大量具有良好自相关和互相关特性的混沌序列,在安全领域具有良好的应用前景.

| Abstract: | Because the computer limited precision effect introduces the chaos degeneration question in one chaos system,this article proposed a method of pseudo-random sequence generation with variable parameter of multistage chaos mapping.Compares one chaos system based on this method construction chaos system to have the pseudo-random sequence cycle to be big,key quantity are many,the key space big superiority,produces the password has a higher safety performance.The simulation result indicated that,this method may produce under the low complexity condition has the good autocorrelation and the mutual correlation characteristic chaos sequence massively,has the good application prospect in the security domain. |
