Abstract: To make audio information broadcast across the Web safely,an audio encryption algorithm based on chaotic systems and the wavelet transform in MPEG background was proposed.Firstly,the signal is added with a random matrix to change the value of signal.Secondly,logistic map is used to scramble and diffuse the position of each signal in time and the wavelet domains for three times.Finally,we can obtain the secure signal.The random matrix used as keys was generated by piecewise Logistic map and the random seeds.The experiment results show the mentioned algorithm not only makes gray histogram uniform and signal correlation weake,but also increases key space and high sensitivity to the keys.Therefore,the audio encryption algorithm has higher security to protect audio information.
