Abstract
A hardware-based digital random number generator is provided. In one embodiment, a processor includes a digital random number generator (DRNG) to condition entropy data provided by an entropy source, to generate a plurality of deterministic random bit (DRB) strings, and to generate a plurality of nondeterministic random bit (NRB) strings, and an execution unit coupled to the DRNG, in response to a first instruction to read a seed value, to retrieve one of the NRB strings from the DRNG and to store the NRB string in a destination register specified by the first instruction.
