一种基于多服务器的分布式电子拍卖方案
A Distributed Electronic Auction Scheme Based on Multiple Servers
摘要
Abstract
Electronic auction is online realization of traditional actions. Due to its privacy protection and security, sealed-bid auction scheme attracts widespread attention. However, most of these auction schemes are based on the assumption of existing trusted third party, which is often difficult to be established in fact. Based on LaGrange threshold secret sharing scheme and BIT comment mechanism, a distributed electronic auction scheme with multiple servers is proposed in this paper. In the bidding phase, based on LaGrange threshold secret sharing scheme, the bidder computes fragmentations of the bidding result and separately gives them to different auction servers. In the opening phase, no less than a certain threshold of servers submit their fragmentations. The final success bidder can be verified by BIT commit based method. It not only prevents a single point of bottleneck of a single auction server, but also cuts down auction process computational overhead. The scheme ensures the protection of users’ privacy, only the identity of the final successful bidder and the relative bid price can be revealed. Analysis results of the security and performance show that it satisfies the requirements of a secure electronic auction scheme. Meanwhile, it can reduce the computation and communication overhead.关键词
