1. A system, comprising: entropy data collected from one or more entropy sources based on event data; one or more entropy pools configured to collect the entropy data, the one or more entropy pools dynamically generated on-demand as the entropy data is collected; and processor pseudo-random number generators (PRNGs) implemented one each per logical processor of the system, each processor PRNG configured to maintain a PRNG entropy state that is reseeded with the entropy data, the processor PRNGs reseeded according to a PRNG hierarchy that comprises one or more levels of the processor PRNGs, and a processor PRNG further configured to generate a random number from a respective PRNG entropy state.
