This paper proposes a Multiparty Private Set Intersection Cardinality (MPSI-CA), where the number of participants in PSI is not limited to two and the ...

We describe a simple two-party protocol in which each party contributes a set as input. The output of the protocol is an estimate of the cardinality of the.

Proposed mPSI-CA is proven to be secure against malicious adversaries in the random oracle model (ROM) under the decisional Diffie-Hellman (DDH) assumption. It ...
