Speech Encryption Based on Wavelet Transformation and Chaotic Map
In this paper a new algorithm is presented for speech encryption. It includes dividing the speech signal into overlapped blocks then shuffling those blocks in the time domain. A second permutation is done for the coefficients of the block which generated from wavelet transform by using chaotic key b...
