声光双稳态系统周期驱动混沌保密通信

Chaos communication with periodic drive acousto-optical bistable chaos system

通过对声光双稳态系统进行周期驱动 ,调节驱动强度可使系统从周期态转变为混沌态。本文提出利用此混沌系统进行保密通信 ,我们先在系统处于周期态时使接收和发送端的两个声光双稳态系统同步 ,再改变驱动信号强度 ,使两系统同时进入混沌态 ,从而使得两个混沌系统具有相同的初始条件和参数 ,即得到两个同步混沌相同 ,在混沌同步的基础上实现混沌保密通信。

Drive by a periodic signal,an acousto-optical bistable system can change its state from periodic to chaos.We proved the ideal with Lyapunov exponent computation.Based on this ideal,we support that we can drive two AOB systems with same periodic signal.When the two systems is in periodic state,we synchronizing them,then change the intensive of drive signal,drive the two AOB systems to chaos.We should get synchronization of two AOB chaos systems.With synchronization chaos system.we can do our secret communication.
