Multi-Point HashDH OPRF using Multiplicative Blinding with Application to Private Set Intersection

ePrint Report: Multi-Point HashDH OPRF using Multiplicative Blinding with Application to Private Set Intersection

Minglang Dong

The privacy set intersection (PSI) protocol with the oblivious pseudorandom function (OPRF) as the core component is a crucial member of PSI family, and the most efficient PSI protocol at present also belongs to this category. Based on DDH assumption, Hash Diffie-Hellman (HashDH) PSI is one of the most classical PSI protocols. Benefiting by its low communication overhead, it still has tremendous research value …
