  • In this paper, a way of secure digital communication based on occasional coupling and generalized chaotic synchronization is proposed. The period of every signal bit is divided into two parts: T1 and T2. During T1, generalized chaotic synchronization is fulfilled, and in T2, the transmitted signal is extracted by a special way. The relation between T1, T2 and the security as well as the performance of signal extraction are also analyzed. Numerical simulations are performed to show the effectiveness of this communication scheme.
