At the end of the protocol one (or both) party should learn the intersection of the two sets Z= X\cap Y and nothing else about the input of the other party. There are many real-world applications in which PSI is required.

Web124 B. Pinkas et al. 1.1 Overview of Our Protocol The starting point for our protocols is the Circuit-Phasing PSI protocol of [PSSZ15] in which O(n) bins are considered and the circuit computes O(nlogn/loglogn) comparisons.Party P 1 uses Cuckoo hashing to map at most one item to each bin, whereas party P 2 maps its items to the bins using simple hashing … WebCircuit-based PSI protocols with almost linear overhead. We show a new circuit-based construction for computing any symmetric function on top of PSI, with an asymptotic overhead of only !(n) comparisons. (More accurately, for any function f2!(n), the overhead of the construction is o(f(n)).) This construction is based on standard Cuckoo hashing.
