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 …

Webtheir approach: in the protocol closest to our optimized proposal (DH-based PSI [19,27]), the client and server reuse the same keys across all executions, which does not provide forward secrecy ... WebNov 17, 2024 · Though DH-based PSI protocols can keep a low communication costs, their computational costs are high due to the expensive public key operation. Cristofaro and Tsudik [ 3 ] utilzed blind-RSA signatures to construct a PSI protocol that could scale linearly in computation with the set size. dairy free games

WebImplementation of a DH-based PSI Protocol We chose the protocol described in [63, 85] for inclusion into the private microblogging solution, also in agreement with the recommendations made in [100]. The decision to use this protocol is because of its fast computation runtime for the given set sizes n and the best communication complexity of … WebApr 7, 2024 · DH-PSI protocol from [23] has an asymptotically faster online phase, but the. ...
