摘要
基于群签名技术和Shamir′s门限方案 ,设计了一个适于分布式松耦合广播 /预约系统使用的安全电子拍卖协议 .协议不仅保证了投标者对所投价位的不可否认性和匿名性 ,而且保证了拍卖代理对接收标书的不可否认性 .与先前工作相比 ,本文的方案提供了较高的安全特性 。
A new distributed secure electronic auction protocol based on group signatures and Shamir′s threshold secret sharing scheme is proposed.This protocol is designed for a loosely coupled broadcast/subscribe architecture.The protocol not only guarantees the non repudiation and anonymity of the bidder,but also ensures the non repudiation of the bid received.Compared with previous work,our protocol can provide more security,and is suitable for large scale distributed auction.
