Investigation on the Simulation of One-Dimensional Discrete Chaotic Digital Generation Circuit

Based on the methodology of digital chaotic circuit design, the modeling and simulation were realized in Matlab/Simulink environment for Logistic and Tent, which are two typical one-dimensional discrete chaotic systems by use of DSP-Builder toolkit implements. The influences of circuit parameter setting on the chaotic sequence and random performances have been taken into account, as a result the potential security risks have been effectively reduced or eliminated. The conclusions in this paper are of theoretical significance in the applications of chaos in information security and secure communications, meanwhile, a new way of thinking has also been presented for the digital implementation of other chaotic systems.
