ABSTRACT:
Disclosed is a method for deriving random numbers at a higher speed than ever before while maintaining desired randomness without spoiling uniformity of the occurrence frequency of each random number. One pulse included in one of two or more mutually-independent random pulse sequences and one pulse included in one of the remaining random pulse sequences are used, respectively, as a start pulse and a stop pulse. Then a time interval between the start pulse and the stop pulse is measured, and the measured value is output. The pulses temporally occur in a random manner, and therefore the obtained sequence of numerical values becomes random numbers. Specifically, in FIG.1, time intervals t1to t4are measured, and these measured values (in FIG.1, four values) are derived as random numbers.
