Abstract: Chaotic strict synchronous technique is the key to achieve chaotic digital secure communication. Based on actual network chaotic speech secure communication platform, the transport protocol is firstly applied in chaotic synchronization. Inspired by chaotic impulsive synchronization, a new chaotic protocol synchronization technology is proposed and studied, so that the key technical difficulties of digital secure communication can be solved. The proposed technology is improved, and a simple protocol synchronous mechanism is engendered. Such technology can be embedded into existing communication system easily, having strong security and practicability.

Key words: Chaotic impulsive synchronization, Protocol synchronization, Chaotic speech secure communication
