A process and system for generating a pseudo-random number is presented. Input data having entropy is gathered in an Entropy Pool and transformed once by a cryptographic hash function. The transformed data forms the internal state of the pseudo-random number generator. The generator forms the output by applying a second cryptographic hash function to this internal state. Finally, the generator updates the internal state by inputting the current internal state and data from the Entropy Pool into a third cryptographic hash function. The output of the third hash function forms the new internal state of the pseudo-random number generator.
