Abstract
A weighted entropy pool service system and methods. Weights are associated with entropy sources and are used to estimate a quantity of entropy contained in data from the entropy sources. An interface is optionally provided to facilitate connecting user entropy sources to the entropy pool service. The quantity of entropy contained in the system is tracked as entropy is distributed to entropy consumers. A persistent entropy pool state file stores entropy across system restarts.
