Abstract

The invention discloses a method and device for calculating a second price sealed auction transaction amount, and electronic equipment, and the method comprises the steps: carrying out the statistics of the high 16 bits of a first quotation, and obtaining a first statistical vector; obtaining a first secret share by using a secret sharing technology according to the first statistical vector; according to the first secret share, calculating a high 16-bit first numerical value of the transaction amount; counting the lower 16 bits of the first quotation according to the first numerical value to obtain a second statistical vector; obtaining a third secret share by using a secret sharing technology according to the second statistical vector; according to the third secret share, calculating a lower 16-bit second numerical value of the transaction amount; and calculating the transaction amount according to the first numerical value and the second numerical value. According to the method, each auction party obtains the transaction amount of the second-price sealed auction on the premise of ensuring the quotation privacy of the auction party, and meanwhile, the number of rounds of communication is reduced, so that the calculation overhead and the communication overhead are balanced.

Description

technical field [0001] The present application relates to the technical field of multi-party privacy and security computing, and in particular to a method, device and electronic equipment for calculating the transaction value of a second-price sealed auction. Background technique [0002] In a second-price sealed auction, each bidder submits a sealed transaction price, and the highest bidder wins the item, but the transaction is made at the second highest price among all bids. If this kind of auction procedure is implemented, the optimal strategy of each bidder is to make the quotation equal to his own complete estimate of the commodity, or in other words, honesty is the best bidding strategy at this time. [0003] In the second-price sealed auction, when calculating the final transaction amount, it is necessary to publicize the quotation of each bidder to ensure the fairness of the entire auction process. [0004] In the process of realizing the present invention, the inve...
