摘要：
In recent years, chaos-based cryptosystems have drawn more and more attention in many disciplines in particular speech encryption. In this paper, we propose speech encryption scheme based on chaos maps for AMR-WB G.722.2 Codec. To increase the security level, we combine chaos maps logistic and Henon for shuffling and scrambling speech in order to have a hybrid chaotic key generator. The proposed algorithm evaluated with both Perceptual Evaluation of Speech Quality (PESQ) and Enhanced Modified Bark Spectral Distortion (EMBSD) measure confirm the efficiency of our proposed cryptosystem scheme.
