Abstract
A random number generator includes an exclusive-OR circuit, a random number determiner, and a random number generation instruction inhibitor. The exclusive-OR circuit obtains an exclusive-OR of outputs from a number of digital circuits. The random number determiner determines whether or not an output generated according to an instruction to generate random numbers is a random number for each of the digital circuits. The random number generation instruction inhibitor inhibits an instruction to generate random numbers to be provided to the digital circuits whose output generated according to the instruction is determined to be not a random number by the random number determiner.
