Title:
Efficient Threshold Private Set Intersection via BFV Fully Homomorphic Encryptions

Authors: JINGWEI HU

Abstract:

In this paper, we consider how to use fully homomorphic encryptions (FHEs) to solve the problem of secure computations over set intersection where one party holds a relatively set of size N_s and the other party holds a relatively small set of size N_r collaboratively compute some functionality over their set intersection without revealing other information. This problem has many applications for online collaboration, for example, fingerprint matching, online dating, and shareriding.
