Abstract

In this paper, we develop a secure multi-attribute procurement auction, in which a sales item is defined by several attributes called qualities, the buyer is the auctioneer (e.g., a government), and the sellers are the bidders. We first present a Vickrey-type protocol that can be used for multi-attribute procurement auctions.Next, we show how this protocol can be executed securely.
