WebMar 16, 2010 · Once we have n bits, we use a PRNG (Pseudo-Random Number Generator) to crank out as many bits as necessary. A PRNG is said to be cryptographically secure if, assuming that it operates over a wide enough unknown n -bit key, its output is computationally indistinguishable from uniformly random bits.

WebWe show how a pseudo-random generator can provide a bit commitment protocol. We also analyze the number of bits communicated when parties commit to many bits simultaneously, and show that the assumption of the existence of pseudorandom generators suffices to assure amortized O (1) bits of communication per bit commitment.
