Designing Mechanisms for E-Commerce Security: An Example from Sealed-Bid Auctions
研究指出，提升电子商务安全不能仅靠计算技术，还需补充经济机制来抑制安全漏洞的利用。以在线拍卖为例，提出了一种分层分区集协议，防止虚假身份投标行为。
ABSTRACT: The use of computing technology is a necessary but not sufficient approach to enhancing e-commerce security. It should be supplemented by the application of eco-nomic mechanisms to design e-processes that discourage the exploitation of security weak-nesses. Mechanisms that function well in traditional commerce should be updated to accommodate new problems raised in e-commerce, such as the lack of authentication. As an illustration, thiezezs research focuses on on-line auction mechanisms and develops a Leveled Partition Set (LPS) protocol for multi-unit sealed-bid auctions. LPS prevents on-line false-name bidding whereby bidders increase their utility by split ting their bids for a large bundle to several smaller bundles under false identities.
