TLDR; (fta) Alice and Bob should each learn the logical AND of their responses, and nobody should learn any other information The SENPAI protocol is proposing a way to do this with cryptography. There's a historical review of other proposed protocols (AMP, JMAP, MFP, SOAP, YGMP, SLP) along with their deficiencies. A SENPAI-MTT protocol is also considered that allows for non-binary interest (MTT=More Than Two). They propose foiling protocol cracking by quantum factoring by basing future SENPAI protocols on lattice based cryptographic methods.
