摘　　要：混沌信号被广泛用于数据加密、保密通信、流体混合等众多领域,论文提出了一种基于参数周期扰动产生混沌信号的方法,使得一个二阶系统混沌化,并设计了该二阶系统的电路,由于该电路只采用了LM358、AD734、MAX038和若干电容、电阻,因此可应用到家电、智能仪表、IC卡等中低档消费电子产品中以实现数据加密。Chaotic signal is widely-used for such fields as data encryption, secure communication and flow mixture. A parameter periodic disturbance method is suggested for generating chaos. A second-order system is presented to illustrate the proposed method and its circuit realization is also given. The circuit uses only LM358, AD734, MAX038 and some resistances and capacitances, and thus can be applied for data encryption of consumption electronic products with low or medium price, including electrical home appliances, intelligent instruments and integrated circuit cards.
