PROBLEM TO BE SOLVED: To provide a random number generator capable of improving the reliability of security by providing the continuation of values different every time when a power source is turned on. SOLUTION: The random number generator for continuously generating random numbers by using a mathematical method, is provided with a storage circuit 1 for preserving the random number to be finally generated from a random number generation function rng (x) arithmetic circuit 2 when the operation of the device is stopped and in the case of next restarting the operation, the random number generation function rng (x) arithmetic circuit 2 generates random numbers on the basis of the value stored in this storage circuit 1. |
