E cient Circuit-based PSI via Cuckoo Hashing

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. 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. lawrenceburg indiana newspaperWebDec 1, 2024 · In terms of works that support computing over the intersection while hiding the values, a prominent approach is Garbled-Circuit-based PSI. proposes an efficient sort-compare-shuffle circuit construction to implement PJC. improves circuit-PSI using several hashing techniques.

WebDec 9, 2024 · The name PSI with bi-oblivious data transfer comes from the fact that f_i output values can be thought as the data to be transferred from P_1 to P_2, but the transfer is bi-oblivious, meaning that neither P_1 nor P_2 knows the input bit b_i indicating which of the two data options was transferred.

WebStep 1. Quantum Teleportation begins with the fact that Alice needs to transmit ψ = α 0 + β 1 ψ = α 0 + β 1 (a random qubit) to Bob. She doesn't know the state of the qubit. For this, Alice and Bob take the help of a third party (Telamon). Telamon prepares a pair of entangled qubits for Alice and Bob. karcher k4 leaking water from the bottomWebAug 3, 2024 · In PSI two parties hold two sets of strings X and Y, respectively.
