Experimental demonstration of bidirectional chaotic communication by means of isochronal synchronization. Europhysics Letters, 81(4), 40005. 10.1209/0295-5075/81/400051286-4854 (online)0295-5075 (print)https://hdl.handle.net/10115/81697We give the first experimental demonstration of simultaneous bidirectional communication through chaotic carriers thanks to the phenomenon of isochronal synchronization. Two Mackey-Glass electronic circuits with chaotic behaviour exchange their signals through a coupling line with delay. When the internal feedback of the circuits and the coupling are accurately matched, isochronal synchronization arises. Under this dynamical regime, we introduce a binary message at both outputs and recover it at the opposite circuit. Finally, we discuss the security of this kind of communication system by analyzing the message recovered by a potential eavesdropper.en-USArticle10.1209/0295-5075/81/40005info:eu-repo/semantics/openAccess
