Private Set Intersection with Delegated Blind Quantum Computing [article]

Michele Amoretti
2022 arXiv   pre-print
In this work, we consider the case of two-party PSI in the honest-but-curious setting. We propose a protocol that solves the server-aided PSI problem using delegated blind quantum computing.  ...  The proposed protocol is correct, secure and blind against a malicious server, and characterized by a quantum communication complexity that is linear in the input size.  ...  Acknowledgements The author would like to thank Anna Pappa for helpful discussions on the MBQC-based multiparty delegated quantum computation protocol.  ...
