Private Set Intersection from TFHE for Cloud Computing Scenarios
Jiayu Qiang and Yi Deng
Abstract
In most scenarios of Private Set Intersection (PSI) computed on a cloud server, the client has a smaller set size and lower computation ability than that of the cloud server, which is known as the unbalanced setting. We use Torus Fully Homomorphic Encryption (TFHE) for the first time instead of the leveled ones to construct a PSI protocol. More precisely, we mainly focus on an adaptive and dynamic setting since the server may provide services to multiple clients at the same time and its data set is updated in real time.
We use TFHE to construct an adaptive PSI for unbounded items with a lower communication complexity of
