A hardware random number generator (HRNG), true random number generator (TRNG), non-deterministic random bit generator (NRBG),[1] or physical random number generator[2][3] is a device that generates random numbers from a physical process capable of producing entropy, unlike a pseudorandom number generator (PRNG) that utilizes a deterministic algorithm[2] and non-physical nondeterministic random bit generators that do not include hardware dedicated to generation of entropy.
