%X 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.
