Secure Receipt-Free Sealed-Bid Electronic Auction
نویسندگان
چکیده
The auction scheme that provides receipt-freeness, prevents the bidders from bid-rigging by the coercers. Bid-rigging is a dangerous attack in electronic auction. This happen if the bidder gets a receipt of his bidding price, which proves his bidding prices, from the auction protocol. The coercers used to force the bidders to disclose their receipts and hence bidders lose the secrecy of their bidding prices. This paper presents a protocol for a receipt-free, sealed-bid auction. The scheme ensures the receipt-freeness, secrecy of the bid, secrecy of the bidder and public verifiability.

Practical Receipt-Free Sealed-Bid Auction in the Coercive Environment
Sealed-Bid auction is an efficient and rational method to establish the price in open market. However sealed-bid auctions are subject to bid-rigging attack. Receipt-free mechanisms were proposed to prevent bid-rigging. The prior receipt-free mechanisms are based on two assumptions; firstly, existence of untappable channel between bidders and auction authorities. Secondly, mechanisms assume the ...

Bid-rigging is a dangerous attack in electronic auction. Abe and Suzuki firstly introduced the idea of receipt-free to prevent this attack. In this paper we point out that Abe and Suzuki’s scheme only provides receipt-freeness for losing bidders. We argue that it is more important to provide receipt-freeness for winners and propose a new receipt-free sealed bid auction scheme using the homomorp...
