Abstract
The present invention is an apparatus for generating random bits from a computer system. The apparatus comprises a rotating storage device operating within the computer system. A rotational latency of the rotating storage device is associated with the computer system accessing information from the storage device with the rotational latency causing the accessing of the information to have an entropy. An extraction mechanism extracts random bits derived from entropy of the rotational latency of the storage device.
