Abstract
A method, an apparatus, and a computer program product for generating and processing random numbers are provided. An apparatus comprises a processing system that includes a processor, a random number generator and a pair of buffers. A first buffer receives low-entropy random numbers generated by the random number generator and a second buffer provides high-entropy random numbers directly to a processing system. The processing system may directly access the second buffer in response to an instruction executed by the processing system. The processing system responds to an interrupt based on occupancy levels of the buffers by conditioning low-entropy random numbers read from the first buffer to obtain high-entropy random numbers that are then stored in the second.
