摘要

本文利用一类特殊的一维分段线性混沌系统，来产生具有均匀不变分布函数和δ自相关函数特性的连续混沌信号，这类连续混沌信号经过不可逆变换可生成具有理想保密性的二进制混沌密码序列．本文分析了该混沌系统的有限精度效应并提出一类ｍ序列扰动实现方法．与传统密码序列相比，混沌非线性反馈密码序列不仅具有丰富的源泉，而且设计异常方便，性能易于控制．

Abstract

A class of one-dimensional piecewise linear（PWL）chaotic system is proposed in this paper.This system is capable of generating chaotic signals with uniform distribution and δ-like auto-correlation fonction. It is shown that these signals can be ed to provide binary chaotic ciphers via non-invertible transformations. Moreover

the finite precision effect of the proposed PWL chaotic systems is investigated

and m-sequencebased peturbation approach is proposed. Comparing with traditional stream encryption methods

chaotic stream ciphers are not only abundant in number

but also easy to design and control.
