摘要:
A method for creating entropy in a virtualized computing environment includes waking one or more samplers, each sampler having a sampling frequency; sampling a sample source with each of the one or more samplers; placing each of the samplers in an inactive state when not sampling; determining a difference between an expected value and a sampled value at each sampler; and providing a function of the difference from each of the one or more samplers to an aggregator.
