Random number generation device, operating method of the random number generation device, and electronic device

Abstract

A random number generation device, operation method of the random number generation device and electronic device are provided. The random number generation device includes an instantiate and reseed function logic configured to receive an entropy input having a size smaller than or equal to a reference size of a reference seed material that may be processed at one time during a crypto operation and configured to repeatedly perform the crypto operation, based on a seed material configured to be processed at one time during the crypto operation in a current crypto operation sequence and an operation result in a previous crypto operation sequence, and a random number generation logic configured to generate random number data.
