a deck of cards, we need one random number from 0 to 51, then another between 0 and 50, etc. Thus a shuffle
is fully determined by the random sequence generated in the prior FAQ. What cryptographic assumptions is this protocol based on? Though there has been much interesting work building commitment schemes out of weaker assumptions, we are using
a rather blunt instrument and assuming that HMAC-SHA256...
