摘 要：Isochronal synchronization (IS) is amongst the most intriguing collective behaviors observed in coupled chaotic oscillators and networks. The oscillators' dynamics behave identically in time, despite time-delays in the coupling signals among them. Such a phenomenon has attracted the attention of researchers due to its potential applications in chaos-based communication schemes [26,27]. In this context, a major advantage of isochronal synchronization is the possibility of handling simultaneous bidirectional transmission requiring as little as one chaotic oscillator at each end of the communication line [26]. Moreover, recent studies found that increased security in the negotiation of secret keys through public channels can be attained [16,24,27]. Thus, chaos-based communication using IS may provide increased efficiency and security as compared to other chaos-based schemes, yet maintaining a simple conceptual framework.
