@Shaggy, I'd suggest asking a new question stating specifically what you don't understand in the answer below and ask for clarification.

comment What's efficient MPC protocol for determining if sum's bigger than y?
My guess is that adding packed ss to Viff would be easy. I am not very familiar with FaiplayMP.

comment What's efficient MPC protocol for determining if sum's bigger than y?
@poncho, thanks for the update. I've seen a number of cases recently where generic MPC is faster than specialized protocols (often due to public key crypto), which is why I asked. Are you aware of any specialized millionaire problem solutions which do not use public-key crypto?

@poncho, do you know if specialized solutions to the millionaire problem are faster than generic MPC solutions? Or which millionaire problem solution is the most efficient?
