Secure Sealed-Bid Electronic Auction Scheme

基于一个群签名方案及公告牌,设计了一个新的密封投标的电子拍卖系统,利用群签名的性质,系统具有可保护投标人的投标价和防止中标人抵赖的特点,而使用公告牌使得在网络中能更方便地进行拍卖,并且使得本协议满足可撤销性及只用一次注册。作者利用了高效安全的群签名方案和公告牌使得协议具有安全性高、步骤简略、方便等特点。

A fair electronic auction system is proposed, which is based on an efficient group signature and bulletin board. The new protocol protects the privacy of the bidders, and the winner can not repudiate his bid and it is easy revocation and one-time registration. It is more efficient and safe than others when we use the bulletin board and the efficient group signature.
