Abstract
Methods and circuitry for generating a cryptographic hash function using a strong pseudo-random generator along with the input data to create high quality pseudo-random keys as indices to pseudo-random functions, as well as a pseudo-random function from 2n bits to 2n bits given a pseudo-random function from n bits to n bits.
