Dh-based psi

WebPublic-key cryptography based PSI. Meadows[27]andHubermanet al. [19] proposed one of the earliest PSI approaches based on public-key, even before the PSI problem was formally defined in [15]. Both were based on the Diffie-Hellman (DH) key exchange, taking advantage of its commutative properties. WebDH-based PSI protocols are the cheapest for these input sizes (equal-size sets of a few hundred items, or sets of highly unbalanced size where the larger set is a few thousand …
