多重加密通信系统的设计与实现

为实现无线信道中的高度保密通信,提出了一种基于DSP平台的多重加密通信系统。加密通信终端以高性能数字信号处理器DSP芯片为核心,融合高级加密算法（AES）、非对称加密算法（RSA）和混沌伪随机序列CPRS（Chaos Pseudo-Random Sequence）三种加密算法,利用电路交换数据业务（CSD）信道进行语音保密通信。文中详细阐述了系统方案的总体框架设计,介绍了系统硬件平台选型及相关硬件和外围接口的设计,并结合系统功能和保密体系,具体描述了系统的软件设计以及总体工作流程。实验结果表明：三层加密算法安全可靠,语音传输延时很小,实现了良好的保密通信目的。

Design and Implementation of Multiple-encryption Communication System

This paper describes a multiple-encryption communication system based on DSP platform,thus to obtain a high-quality secure communication in wireless environment.The encrypted communication terminal uses high-performance digital signal processor(DSP) as the core,integrates three encryption algorithms,including AES,RSA and Chaos Pseudo-Random Sequence(CPRS),and realizes voice secure communication over circuit switched data(CSD) channel.This paper discusses in detail the overall structure of the system,gives t...
