Anti-collusion multi-party private set union protocol in low-bandwidth scenarios

Aiming at the problems of the existing multi-party private set union (MPSU) protocols, such as a large number of interaction rounds and excessive communication overhead, which prevented them from being effectively applied in low-bandwidth scenarios, an oblivious matching permutation method based on...
