A Post-Confirmation Method for Quantum Sealed Bidding Auction

Abstract

The invention discloses a post-confirmation method of quantum sealed bidding auction, which is characterized in that in the quantum sealed bidding auction, after each bidder sends his bidding price to the auctioneer, he processes his own bidding price information, Sent to other bidders, when the auctioneer announces the winner and its bid price, other bidders can verify the authenticity of the winner based on the previously received processed bid information. The purpose of the present invention is to solve the problems that the post-confirmation method of the existing quantum sealed bidding auction protocol has high operation and measurement complexity, requires quantum entanglement resources and quantum memory, and is difficult to realize, so that any bidder can verify the authenticity of the final winner To ensure the fairness of the auction.

Description

technical field

[0001] The invention relates to the field of quantum sealed bidding auction and classical post-processing, in particular to a post-confirmation method suitable for ensuring the fairness of the auction in the quantum sealed bidding auction process. Background technique

[0002] With the rapid development and wide application of Internet technology, various types of e-commerce are constantly appearing on the Internet, and e-auction is one of the most important e-commerce applications. A well-designed e-auction system can achieve the optimal allocation of resources and provide open , a fair and just economic transaction environment, which is of great practical significance to the healthy development of e-commerce, and helps to establish a social credit mechanism. At the same time, electronic auctions involve a variety of network and information security technologies, which can not only be used It is not only used in electronic auctions, but also in other e-comme...

Examples

Embodiment Construction

[0034] The technical solutions of the present invention will be described in detail below, but the protection scope of the present invention is not limited to the examples.

[0035] In this embodiment, a post-confirmation method of a quantum-sealed bidding auction is performed in the following steps:

[0036] Step 1: In an auctioneer Alice and N-1 bidders {B 1 ,B 2 ,...,B j ,...,B N -1} in the auction process, any jth bidder B j with i-th bidder B i share a key K ij , j, i=1,2,...,N-1 and i≠j;

[0037] Before the auction starts, any jth bidder B j with i-th bidder B i Share a 2n long key, denoted as K, through the quantum key distribution (QKD) method ij , the key can not only be used to verify the jth bidder B j and the i-th bidder B i The identity of the bid price can also be connected to the bid price to achieve the purpose of protecting the bid price information;

[0038] Step 2: Any bidder sends the processed bid price to all other bidders;

[0039] Step 2.1: T...
