A Privacy-preserving Distributed Multi-attribute Reverse Auction Scheme with Public verification using Threshold Paillier cryptosystem

Abstract

With the rapid updating of Internet technology, electronic auction network environment is more complex,so the electronic auction security requirements are getting higher and higher. In addition, thestudy of multi-attribute auction research on security is still very lacking. In this paper, a secure multiattributereverse auction scheme is proposed. It uses the paillier threshold homomorphic cryptosystemand multiple servers to prevent conspiracy attack between buyer and auction servers. Moreover,the techniques of oblivious transfer and anonymization are also used to achieve the bidder privacyand anonymity. Finally, the scheme achieves the public verification of auction process and auctionresults and the security analysis is given.
