一种基于位映射的混沌加密算法及其实时语音通信实现

摘要

由于人们对语音通信的安全越来越重视，故保密通信算法就越来越多人研究了。提出了一种基于位映射的混沌加密新方法并利用ARM开发板搭建一个语音通信系统：在发送端对语音进行采集、编码、混沌加密，并通过网络进行传输，同时在接收端端进行解密、解码及播放。实验结果表明，该方案可以实现可靠，快速地传输实时语音数据，且失真较小。%As people pay more attention to the security of voice communication,there are a lot research on secure com-munication algorithm.This paper presents a new method of chaotic encryption based on bitmap and use it to build a voice communication system with ARM development boards.At the sender of the system includes speech acquisition,encoding, chaotic encryption and transmission over the network,while the receiver includes decryption,decoding and playback.
