Abstract

Abstract: The Piecewise Linear Chaotic Map with a Segment Number Parameter（SNP-PLCM） is analyzed in detail.Based on SNP-PLCM，a chaotic pseudorandom sequence generator is presented.The generator employs perturbation strategy of control parameter and output sequences to avoid dynamical degradation of digital chaotic systems.Theoretical analysis and computer simulation results show that the chaotic pseudorandom sequence generator can get high quality sequences.

Key words: Piecewise Linear Chaotic Map with a Segment Number Parameter（SNP-PLCM）, chaotic system, pseudorandom sequence generator

摘要： 对区间数目参数化分段线性混沌映射（SNP-PLCM）的密码学特性进行详细分析，并以此为基础，提出了一种基于区间数目参数化分段线性混沌映射的伪随机序列发生器。该发生器同时利用控制参数扰动策略和输出序列扰动策略避免数字化混沌系统的动力学特性退化。理论分析和仿真实验结果表明，该算法产生的伪随机序列具有理想的性能。
