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.
