Encrypted audio transmission via synchronized chaotic Nd: YAG lasers
In this paper, encrypted audio transmission via synchronization of coupled chaotic Nd:YAG lasers in master-slave configuration is numerically studied. In particular, we resort to recent results from complex systems theory to achieve chaos synchronization. So that, enconding, transmission, and decoding of confidential audio messeges in chaotic optical communications are presented. In addition, we show transmission of encrypted audio messages when parameter mismatch and channel noise are considered. In order to illustrate this robustness synchronization property, we present the encrypted transmission of audio messages via an improved chaotic transmitted signal, and we obtain at the receiver that, the original audio message is appropriatelly recovered.
