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. WebPSI protocols in the semi-honest setting were actually faster than other special-purpose ones. Since then, the results in OT-based PSI have made special-purpose PSI protocols significantly faster. Kamara et al. [16] presented techniques for both semi-honest and malicious secure PSI in a server-aided model. In this model the WebPSI as the ultimate cryptographic tool, allowing multiple parties (di- agnosed users and healthcare providers) to privately match contact information and notify users who may … iris clean room
