A pseudo-random number generator comprises: (a) a plurality of first-tier means each capable of receiving an entropy input and generating a respective hash output; and (b) a second-tier hashing means, which takes as input the respective first-tier hash outputs and generates as output a pseudo-random number. The generator of the present invention has particular application in cryptosystems, and particularly in public key cryptosystems where long sequences of data chosen from a large space of possible sequences need to be created quickly. |
