I thought Tinder had it solved...
- dripton 10y agoTinder is Trent in this protocol. As long as both Alice and Bob trust Trent, that works. But Trent can cheat.
- twokwy 10y agoYeah, Tinder achieves exactly the objective described of both parties only finding out if both parties' responses are 1. (And suffers from the issue they discuss where 'detectable cheating' - in this case, swiping right regardless to maximise information gain - is difficult to prevent). But, as others have mentioned, it relies on the trusted third party, that is to say Tinder, being trustworthy and not performing what the paper amusingly refers to as a 'Matchmaker In The Middle' attack.
