Abstract
Systems and methods for providing a multiple source entropy feed for a PRNG that is used to generate server-side encryption keys are disclosed. A data recovery manager may collect additional entropy sources that feed into the PRNG between each key generation. The entropy may be collected from a variety of sources, for example, high-resolution timer intervals between input/output interrupts, hard disk access operations, and the like. The number of bits of entropy collected may be configured for each key generation.
