| Abstract(in English) | We investigated the possibility of generating a pseudo random number sequence with good performance by using chaotic dynamics.In this paper, we used the logistic map to generate a pseudo random number.To alleviate numerical calculation errors, we modified the logistic map to an integer logistic map.We converted the time series data obtained from the integer logistic map to binary sequences.Then, we evaluated the performance of the pseudo random number sequence by using the NIST test.In particular, we investigated the influence of the accuracy of numerical precision on the performance of random numbers, even if the same bifurcation parameter values were used.As a result, even if the accuracy of numerical precision is increased, the number of the NIST certification passed does not show large variation. |
