Abstract:

 A simple synchronization method by only transmitting a single driving variable for a new Lorenz-like attractor is proposed. Furthermore, based on the chaotic synchronization method, a secure communication system is proposed. Since chaos synchronization can be achieved by transmitting only one channel information contains a single variable from driving system to response system, this method is more practical. Theoretical deduction and computer simulation show the effectiveness of the proposed method.

Key words:  chaos synchronization; secure communication;  Lorenz-like chaotic system; single driving variable
