Abstract
Disclosed is a random number verification method and apparatus capable of quickly detecting the fact that a random number generation device designed to generate substantially authentic random numbers has become unable to generate authentic random numbers due to a malfunction, wrongful manipulation or the like. When random numbers randomly generated as n kinds of values are verified, a random number verification method according to one aspect of the present invention comprises a random number acquisition step of selecting a number m of the values, a counting step of counting the number of ones occurring p times (0≦p<m) in the n kinds of values, a comparison step of comparing the number obtained in the counting step with a predetermined first threshold, and a determination step of, when it is found the number is greater than the first threshold as the result of the comparison step, determining that the random numbers have a problem.
