Private Set Intersection (PSI) is a problem within the broader field of secure computation. The PSI problem There are two friends Alice and Bob such that Alice has a set of items $A=(a_1,\ldots,a_n)$ and Bob has the set $B=(b_1,\ldots,b_n)$. The goal is to design a protocol by which Alice and Bob obtain the intersection $A\cap B$, under the following privacy restriction: The protocol must not reveal anything about items that...
