A New Quantum Sealed-Bid Auction Protocol with a Set of Local Indistinguishable Orthogonal Product States

Quantum sealed-bid auction (QSA) is a special form of transaction with significant applications in the economic and financial fields. Using unique set locally indistinguishable orthogonal product (LIOP) states, we propose new QSA protocol this paper. In protocol, bid message encoded as quantum sequence LIOP different particles states are transmitted separately. Even though an attacker obtains portion particles, they cannot recover entire because local indistinguishability states. Once auctioneer announces winner’s bid, all bidders able to confirm authenticity their bid. With help semi-honest third party, collusion between malicious bidder can be discovered. Finally, our capable meeting requirements for secure auctions through security completeness analysis. Additionally, proposed does not require any entangled resources complicated operations, so it easily implemented practice.
