基于ARM的混沌序列的产生及其性能分析

摘要

This paper constructs a new four-dimensional chaotic system which is based on an original chaotic system by introducing a state feedback controller. And the new chaotic system's properties are verified theoretically by analyzing bifurcation、 attractors and Lyapunov exponent. Then ARM technology is used to generate digital chaotic PN (Pseudo-random) sequence. Moreover, the NIST test suites is applied to analyse the quality of the PN sequence. It is demonstrated that the PN sequence can be used in secure communication.%根据一个已有的混沌系统,构造出一个新的超混沌系统,并对该超混沌系统进行分析,包括吸引子、Lyapunov指数和分岔图,证明了该系统有着复杂而丰富的动力学特性.然后对超混沌系统进行离散化,并利用ARM处理器实现.抽取混沌序列并用NIST标准进行了性能测试,实验证明该混沌序列具有良好的随机性,可应用于加密和通信等领域.
