摘要
为了实现标价的匿名性,提出了一种基于Hash链的新的电子拍卖协议,创建了一条Hash链,把链的根和随机数的Hash值一次提交到拍卖中心。相比基于Shamir秘密分享方案的多方计算协议实现多个拍卖代理分享投标人身份的电子拍卖,该方案在计算效率和通信效率上有显著提高。
Security and privacy are the crucial conditions in the seal-auction design.For an anonymous bid,a new electron auction is presented based on Hash chain with constructing a Hash chain,root of the chain and Hash value of the random number submitted to the auctioneer by only one time.The scheme differs from the previous electronic auction of secret sharing of the multi-computation protocol that multi-proxy of auction share the identities of the bidders.Its efficiency is distinctly improved in computation and communication.
