Abstract :
A novel single-channel digital secure communication scheme based on dual synchronization of chaos in Colpitts circuits is proposed. Two binary messages, modulated by the OOK scheme and mixed together with two chaotic waveforms, serve as the only transmission signal through a single channel. Simulation results show that two messages can be successfully recovered at their respective receivers. The proposed scheme shows tremendous advantages in terms of effective utilization of spectrum resource for multi-user communications and potential applications in secret sharing systems.
