Research Abstract

We have studied to develop a new secure communication system using paired-chaotic system through the time-delayed coupling. The following results were obtained in numerical simulations and electronic circuit experiments. (1) We developed the new time-delayed feedback method with an unstable controller, (2) it was pointed out that the paired-chaotic system based on unstable controllers can be applied to secure communication systems, (3) it was found design guidelines to apply communication system compensating transmission delay time the anticipation chaos synchronization.
