WebAug 3, 2024 · In PSI two parties hold two sets of strings X and Y, respectively. 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.

"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. " - Circuit based psi
