Abstract (in Japanese) (See Japanese page) 
(in English) In this report, we generated pseudorandom numbers using chaotic dynamics and investigated its performance as pseudorandom numbers with post-processing by the XOR operation. Then we analyzed whether the quality of the pseudorandom numbers post-processed by the XOR operation is improved or not. In this study, the pseudorandom number generator is an integer logistic map which reduces numerical errors. First, we converted time series data obtained from the integer logistic map to binary random numbers by setting a threshold value. When we generate chaotic random numbers, we varied the numerical precision. Then, using the NIST test, we evaluated the quality of pseudorandom numbers which is post-processed by the XOR operation. As the results, if numerical precision is high enough, the quality of the pseudorandom numbers did not change by the XOR operation. On the other hand, if numerical precision is insufficient, we found that the quality of the pseudorandom numbers declined by the XOR operation.
