Amortizing Circuit-PSI in the Multiple Sender/Receiver Setting

ePrint Report: Amortizing Circuit-PSI in the Multiple Sender/Receiver Setting

Aron van Baarsen, Marc Stevens

Private set intersection (PSI) is a cryptographic functionality for two parties to learn the intersection of their input sets, without leaking any other information. Circuit-PSI is a stronger PSI functionality where the parties learn only a secret-shared form of the desired intersection, thus without revealing the intersection directly. These secret shares can subsequently serve as input to a secure multiparty computation of any function on this …
