摘要: 为了实现投标者的身份匿名,给出了一个基于RSA函数的M+1电子拍卖方案,任何投标者不能否认所投的标书,未中标价不会被泄露。该方案执行开标算法至多需要P轮交互,至多2p log 2t次模乘法运算,其中P是标价的个数,t是RSA公钥。计算量与投标者的数量无关,方案安全、高效,远高于现有拍卖方案的效率。

Abstract: Security and privacy are the crucial condition in the seal-auction design. A new scheme for (M+l)-st electronic sealed-bid auctions based on the RSA function is presented, which preserves losing bids and bidders' s anonymous identities. No bidder can repu
