中文摘要：

通过分析一个四翼三正Lyapunov指数超混沌系统的基本特性,获知了3个可调参数对系统动力学特性的影响,得到最佳可施加扰动的参数选择方案,构造出一个新的参数扰动超混沌系统.利用嵌入式系统中的AD转换器,将其悬空,得到一个能够采集真随机电路噪声的电路.将此电路噪声数据做适当变比后,作为参数扰动量加入超混沌系统中,使得超混沌系统的输出不再是一个伪随机序列,而是一个真随机信号.

英文摘要：

By analyzing the basic characteristics of a four-wing hyperchaotic system with three positive Lyapunov exponents,we find out the influences of three adjustable parameters to the dynamics of system,and determine the best perturbed parameter for generating a new hyperchaotic system by parameter perturbation.A new circuit noise sample circuitry is constructed by using a floating AD input in an embedded system.After amplitude-scale transformation,and the circuit noise data is added to the hyperchaotic system as a parameter perturbation,the output signal of this system will be a true random signal rather than the pseudo one.
