基于非规则二值化的伪随机序列生成方法
Pseudo-random sequence generating method based on irregular binarization
摘要
Abstract
This paper proposed an irregular binarization method based on the theory of high-dimensional chaotic systems for obtaining the binary sequences of good randomness and safety.In this method,the dimension and the distribution of the sequences determined the threshold when quantified a high-dimensional sequence into a one-dimensional sequence.According to the obtained threshold,the high-dimensional sequences distribution area realized irregular segmentation.This method used the reasonably irregular segmentation method to finish the binarization of high-dimensional sequences.Considering the advantages of linear feedback shift register(LFSR) and high-dimensional chaotic system,it introduced selection mechanism and cyclic iteration structure to generate a binary pseudo-random sequence.The results of theory analysis and simulation show that the generated binary sequences have good chaotic characteristics,good qualities of randomicity and security.关键词
