摘　　要：在P2P网络中实现电子拍卖的功能对于P2P技术具有重要意义,这将意味着电子商务同样可以在P2P网络中广泛应用。然而,匿名性、投标价保密性、抗勾结性等安全问题一直是电子拍卖研究的难点问题,一种合理的解决方法是将盲签名、知识证明、可验证的数字签名加密算法引入到电子拍卖协议中。这样不仅可以很好地解决P2P网络无中心服务器的不足,还使得系统的安全性能得到显著提高。P2P technology is a new distributed network model which does not dependent on servers. It is significant to achieve electronic auction in P2P networks. This means that e-commerce in P2P networks can be widespread application. However, the security issues such as anonymity, confidentiality of bidders＇ quotations, anti-collusion are still the difficult problems in e-auction. A good solution is to deploy blind signature, knowledge-prove and verifiable encryption of digital signatures in e-auctlon protocol. It will not only resolve the disadvantage that no centers in P2P network, but also improve safety performance of the protocol.
