The well-known auction is English auction. This is an auction such that bidders bid up a price, and the highest bidder is determined as the winner when bidding time is over. On the other hand, for selections of order-received constructor of public-works, another type of auction, first-price sealed-bid auction is generally used. In this type of auction, first, each bidder bids for her/his price, and when the bids are opened, the highest(lowest) price bidder is determined as the winner, and gets goods or works at the price for which she/he bids. In this paper, we introduce the current technical trends of electronic first-price sealed-bid auction protocols, using cryptographic techniques for the purpose of keeping bidders' privacy and robustness of the protocols.}, pages = {15--21}, title = {電子オークションプロトコルの技術動向 ―第一価格秘密入札プロトコルについて―}, volume = {16}, year = {2003}, yomi = {オオタ, カズオ and イマイ, サトル and モリタ, ヒカル} }
