Audio signal encryption using chaotic Hénon map and lifting wavelet transforms [PDF]
The European Physical Journal Plus, 2017 We propose an audio signal encryption scheme based on the chaotic Hénon map. The scheme mainly comprises two phases: one is the preprocessing stage where the audio signal is transformed into data by the lifting wavelet scheme and the other in which the ...
