Random number calculation device, random number calculation method, encryption device, and random number calculation program

摘要

There is provided a random number calculation device and the like capable of calculating highly accurate random numbers with a memory capacity that does not depend on accuracy. The random number calculation device 101 calculates a first random number based on a given number, and a random number calculation unit 102 that calculates a first random number based on a given number, and a second random number corresponding to the given number in a target numerical range. Based on the frequency information indicating the cumulative frequency related to the frequency included in the numerical value interval when the numerical value interval including the second random number is determined with desired accuracy, the numerical value interval corresponding to the first random number is specified. And a specifying unit 103.
