A provable secure sealed‐bid multi‐attribute auction scheme under semi‐honest model

Abstract

SUMMARYSecure electronic auction protocol attracts increasing attention in the field of information security research. A variety of secure electronic auction protocols have achieved a lot. However, those studies mainly focus on price‐based auction model. There are few literatures involving security issues of multi‐attribute e‐auction. In recent years, the existing literatures mainly focus on the winner determination problem of multi‐attribute auction, but research of multi‐attribute e‐auction just begin from the perspective of information security. The proposal intends to start with the multi‐attribute e‐auction protocol, explores the different results in the multi‐attribute auction model because of different bid structures, focuses on qualitative attribute‐based winner determination auction model, proposes a new qualitative attribute‐based sealed‐bid multi‐attribute auction scheme under semi‐honest model for the first time. According to the security analysis and computation comparison, it provides strong bid privacy, public verifiability, and reasonable computational cost. Copyright © 2013 John Wiley & Sons, Ltd.

A Fair and Secure Reverse Auction for Government Procurement

“…In 2014, Shi [4] utilized the private set intersection proposed by Freedman et al [17] and Paillier's [18] encryption system to protect the privacy of bids. Unfortunately, we should point out that buyers can do illegal things that are contrary to fairness in Shi's proposal.…”

“…Our protocol focuses on the reverse auction, and it was designed based on one buyer and n sellers. In addition, if desired, it can be extended easily to the double auction like Shi's auction protocol [4].…”

“…However, it was a single-attribute-based auction. Also in 2014, Shi [4] utilized the Based on how they determine the winner, auctions can be classified into single-attribute auctions and multi-attribute auctions [3,4]. In a single-attribute auction, the price is often the only determinant of the auction.…”

“…In 2014, Shi [4] proposed a provable secure, sealed-bid, multi-attribute auction protocol based on the semi-honest model. However, we found that it is vulnerable to the buyer's illegal operations, which can result in unfairness.…”
