Abstract

Vickrey-Clarke-Groves (VCG) is a type of sealed-bid auction of multiple items which has good economic properties. However, VCG has security vulnerabilities, e.g. it is vulnerable to auctioneer fraud. To make VCG more practical, bid prices must be well protected. To tackle this challenge, we propose a bidder-oriented, privacy-preserving auction scheme using homomorphic encryption, where the bidders can calculate the results by themselves, and the auctioneer is able to verify the results. Compared to previous research, our scheme is more trustworthy with stronger privacy.
