comment Verify product without revealing multipliers
Agreed but the question does say "without revealing multipliers" which I took to mean that each party's contribution remains private. I'm not sure why that is needed, I just took the requirement at face value and worked within it's additional constraint. If it were only the case of generating a fair random value, then the coin flipping protocol in your answer suffices and is more efficient.

comment Where can I find useful data for cryptography/coding theory?
The fun part is getting Wolfram Alpha to generate a safe prime, short of running this query over and over again: {#,PrimeQ[#]}&/@{(RandomPrime[{2^1023,2^1024}]-1)/2}

comment Mapping points between elliptic curves and the integers
Thanks! This is useful. Hopefully accepting this answer won't discourage other answers for other types of curves (e.g. ones that are not supersingular—Telex for example relies on DDH.)
