混沌在序列密码系统中的应用

摘要

混沌信号序列的产生是混沌理论应用于信息加密系统中的一个重要问题，文章讨论了混沌信号序列产生的方法，同时提出了一种以混沌信号序列为密钥的序列密码系统，阐述了该系统的优越性，并采用CPLD与MCU完成了该系统的硬件实现。%How to generate chaotic signal sequences is very important in the application of chaos theory in information encryption system.This paper discusses the method of generating chaotic signal sequences, and proposes a stream cipher system based on the key of chaotic sequences.The superiority of the system is introduced.A new hardware implementation is presented by using CPLD and MCU as well.
