摘要
针对低维混沌系统保密性较差,复合混沌系统结构复杂、加密速度较慢等问题,利用时滞混沌系统的无穷维混沌特性,研究了自时滞Rossler系统的混沌同步构造,理论证明了新系统的渐近同步的充分条件,并将其引入到音频保密通信中去.实验仿真结果表明该时滞系统具有较好的数据通信保密性和可操作性.
There exists some problems such as the secrecy capability＇s usually decreasing in using low dimensional chaotic sequence, the compound chaotic system＇s being complicated in its structure, and low encrypting speed. Time-delay system has an infinite-dimensional state space, which is adopted to study synchronization structure of time-delay chaotic Rossler system. The sufficient conditions of asymptotical synchronization are proved, which will be applied to audio frequency secure communication. The simulation experiments demonstrate that the system occupies data traffic security and is easy to operate.
