摘　　要：文中我们针对声光双稳态混沌系统提出了参数调制的方法实现保密通信,计算研究表明,参数调制虽然对混沌系统有一定的改变,但并不改变该系统的伪随机的特性,我们还计算模拟了该方法,并讨论了对其的影响因素。In this paper, a way of chaos secret communication based on parameter modulation is proposed. Our study shows that after parameter modulation some characters of the output of AOB chaos system are still kept, the time sequence of chaotic output still has continuous power spectrum, and looks like a random output. So information could be hid in the sequence. Computer simulation has also proved that secret communication with parameter modulation of AOB chaotic system is feasible. We have also studied influence factor of this system and their effects on secret communication.
