Privacy-Preserving Distributed Set Intersection
Qingsong Ye, Huaxiong Wang, and Christophe Tartary
Abstract
With the growing demand of databases outsourcing and its security concerns, we investigate privacy-preserving set intersection in a distributed scenario. We propose a one-round protocol for privacy-preserving set intersection based on a combination of secret sharing scheme and homomorphic encryption. We then show that, with an extra permutation performed by each of contacted servers, the cardinality of set intersection can be computed efficiently. All protocols constructed in this paper are provably secure against a semi-honest adversary under the Decisional Diffie-Hellman assumption.
