Abstract:
1. A random number verification apparatus for use with a random number generation device, comprising: a random number acquisition circuit to select a number m of the random numbers generated by the random number generation device, wherein the random number generator generates n possible values, wherein n is a finite, natural number that is greater than 1, and wherein m is a multiple of n; an individual-value counting circuit to classify said m random numbers by said n kinds of values, and count the number of times each of the n kind of values occurs in said m random numbers generated by the random number generation device; an occurrence frequency-specific value counting circuit to count the number of the n kind of values occurring p times, wherein p is a predetermined number and (0≦p≦m), in accordance with the counting result of said individual-value counting circuit; a comparison circuit to compare said number of values occurring p times obtained in said occurrence frequency-specific value counting circuit with a predetermined first threshold, and, to determine that said random number generation device has a problem when said number is greater than said first threshold;
