WebIn this work, we propose new circuit-based protocols for computing variants of the intersection with an almost linear number of comparisons. Our constructions are based on new variants of Cuckoo hashing in two dimensions. We present an asymptotically efficient protocol as well as a protocol with better concrete efficiency. WebNov 2, 2024 · The key features of our protocol are a rich set of SQL-like join/select queries and the ability to compose join operations together due to the inputs and outputs being generically secret shared between the parties. Provided that all joins operate on unique primary keys, no information is revealed to any party during the protocol.

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.
