一种安全的多属性拍卖模型

网络拍卖不仅成为电子商务不可分割的部分，而且是自治Agent和多Agent系统(MAS)技术的重要应用领域.同时，拍卖作为一种有效的资源分配形式，在联盟生成等MAS问题中有着重要的应用，因而受到学者们越来越多的关注.拍卖的安全性、隐私性特征是拍卖研究的重要方面.给出了一个一般的多属性拍卖模型和一个安全的多属性拍卖协议——SVAMA协议，并证明了SVAMA的一些重要性质，如Strategy-proof等.并与已有的多属性拍卖和使用的安全方法进行了比较，部分改进了David，Brandt等人的工作.

A Secure Multi-Attribute Auction Model

Internet auction not only is an integral part of electronic commerce but also has become a promising field for applying autonomous agents and multi-agent system(MAS)technologies.Meanwhile,auction,as an efficient resource allocation method,has important application in decentralized scheduling problems and MAS problems,such as coalition formation and has received more and more attention among scholars.Multi-attribute consideration for a resource should be a common phenomenon in an auction;however,it has received decreasing levels of attention.Also,the secure mechanisms and privacy of an auction are important aspects in implementing an auction.A general auction model is given and a Vickrey-type multi-attribute auction model is studied.For trust problems among participants in an auction,in this model,a mobile agent is introduced for a decentralized implementation during the auction.Furthermore,a secure two-party computation protocol is introduced for the privacy demand of bidding.Finally,a secure protocol named SVAMA comes out for the model.SVAMA has some useful properties like strategy-proof,false-name proof,Pareto efficient,etc.The model presented in this paper is more general compared with the existing multi-attribute auction models,and has a dominant strategy for sellers,also has the property of false-name proof.These characteristics are the improvements for the existing multi-attribute auction methods,improving the work of Esther David,Felix Brandt,et al.
