ABSTRACT:
A random number generator includes one or more pseudorandom data sources that generate pseudorandom data, a randomness accumulation facility that receives pseudorandom data from the one or more pseudorandom data sources, a storage facility that stores a random value generated by the randomness accumulation facility, and an application programming interface (“API”), operating independently from the operation of the randomness accumulation facility, that retrieves, upon request by a software application, the random value currently stored in the storage facility and provides a random number to the software application. The pseudorandom data is hashed with a previously-stored random value and a first counter value and may be encrypted before storing in the storage facility. Likewise, the API hashes the current random value with a second counter value before outputting the random number thus generated, decrypting the current value first if necessary.
