Efficient Multi-party Private Set Union Resistant to Maximum Collusion Attacks
Abstract
Multi-party Private Set Union (MPSU) enables multiple participants to jointly compute the union of their private sets without leaking any additional information beyond the resulting union. Liu et al. (ASIACRYPT 2023) proposed the first scalable MPSU protocol fully based on symmetric key encryption (SKE), which designates one participant as the "leader" responsible for obtaining the final union. However, the protocol assumes that the leader does not collude with other participants, which weakens its practicality. In this work, we design a scalable MPSU protocol,
