摘要
为了产生性能良好的伪噪声序列,该文提出了一个新的混沌系统。基于该系统和数字信号处理器研究了混沌伪噪声序列的一种产生方法,对获得的序列进行了随机性测试,测试结果及密钥空间、密钥敏感性分析表明,该序列性能良好并能满足信息加密的需要。
A new chaotic system was put forward in this paper to produce better performance PN（Pseudo-noise） sequences.And a method to produce PN sequence was studied based on the chaotic stem and digital signal processor（DSP）.In addition,the PN sequences was tested by a test software which was issued by national institute of standard and technology（NIST）.The results of test report,key space and key sensitivity indicate that the performance of PN sequence is good and is fully enough to meet the demand for encryption.
