摘要
针对语音信号的加密问题,基于MATLAB软件编程,利用移频函数对语音信号进行移频加密,并在此基础上给出了一种改进方法,将一个语音信号进行分割加密,从而提高加密的效果。
Aiming at the problem of encryption of speech signal, based on MATLAB software programming, using frequency shift function to shift frequency encryption, and on this basis, an improved method is presented to segment a speech signal into encryption, so as to improve the effect of encryption.
