Abstract:
An apparatus for balancing consumption of random data, comprising an entropy manager operable to: responsive to receipt of a request for random data, monitor one or more events associated with a plurality of entities and access one or more rules; determine whether a higher level of entropy associated with the random data is required by analyzing the one or more events in accordance with the one or more rules; responsive to a determination that a higher level of entropy is not required, set an entropy state associated with the entropy to a lower level of entropy and obtain random data from an entropy source having a lower level of entropy; and responsive to a determination that a higher level of entropy is required, switch an entropy state associated with the entropy to a higher level of entropy and obtain random data from an entropy source having a higher level of entropy.
