An Efficient Quantum Sealed Bidding Auction Scheme Based on the Correlation of Genuine Five-Qubit Entangled State
In this paper, an efficient quantum sealed bidding auction scheme based on genuine five-qubit entangled state is proposed. The scheme utilizes the correlation of quantum entangled states to transmit bidding information. It can use an entangled state to transmit two bits of bidding information, which greatly improves the transmission efficiency. In order to avoid collusion between bidders and auctioneer, we introduce a semi-trusted third party Trent. His supervision during the whole auction process can help participants trust each other and reduce the possibility of internal attacks. Finally, the security of the scheme is proved, and the scheme is more economical and feasible.
