NUNEZ, R.. Comunicador experimental privado basado en encriptamiento caótico. Rev. mex. fis. [online]. 2006, vol.52, n.3, pp.285-294. ISSN 0035-001X.

An Encrypted Information Experimental Communicator (EIEC) is presented. It's realization is based on two Lorenz explicit synchronized circuits. All the chaotic dynamics of the circuits were studied and analysed using DSP techniques. Regarding to our real/time application, -on bidirectional audio communications field-, the optimum conclusion was to make the synchronization and the hidden information communication by the medium chaotic dynamic variable and by the most dissimilar chaotic dynamic variables, respectively. Through the complete characterization of the bidirectional channels, we got the minimum characteristics (i.e., waveform and spectrum magnitude) of the private information that it must have just for to make a confidential and robust communication. The EIEC prototype, still doing well for academics and research purposes.
