摘要
随着时代的发展,信号的加密已经成了现在人们保护重要信息的重要手段,但是如何确保信号的安全性却是一个关键问题。基于压缩感知的相关知识,提出了一种基于对称密码的信号加密解密方法,并且以语音信号为例对其进行了仿真测试。压缩感知是近年来新提出的一种采样理论,将其与密码学理论相结合,设计出了一种新的既能保证信号高安全性,又能具有压缩感知传输信号量少、速度快等特点的加密方法。
This paper proposes a new method to encrypt and decrypt signal based on compressed sensing in symmetric cryptography,and select voice signal as example to exiperiment.Compressed sensing is a new sampling theory in recent years.In this way,it proposes a new method for signal encryption and decryption combined with compressed sensing.The method not only guratee security of signal,but also can reduce the content of transminssion and improve the efficency.
