| Abstract: | Random number generator is widely used in system simulation,testing,information security,cryptography and other fields;this paper introduces the concept of CNNs circuit model and constructs a chaotic system based on the 3-cells CNNs.For the of unsatisfactory statistical performance of pseudorandom number sequences generated by the chaotic methods,the methods of local magnified and time-varying parameters were given,and good random variables are obtained.Computer simulations show the effectiveness of the proposed method. |
