摘　　要：电子商务的发展离不开网络安全的支持,目前的主流技术是以密码学为基础,如遵循X.509标准的PKI体系,但数字证书只能保障一次交易的安全性。由于电子商务中信息的异步性,无法预测交易的风险,对已造成的损失常常是无法挽回的。而声誉评估就是根据以往的交易历史来预测将来的行为,从而减少交易风险。另外,电子商务中的匿名欺骗可通过数字证书加以防范。因此,将在线声誉评估与数字证书结合起来,可进一步增强网络安全,减少风险,促进电子商务的发展,所以,声誉系统是对目前基于密码学的网络安全技术的一种重要补充。The security is the basis of e-commerce. The key technology of security is based on cryptography, such as X.509. But the key problem is that it cannot forecast the risk in the oncoming transaction because of the asynchronous information. Considering that the essence of reputation system is to forecast the risk according to your transaction history and that the anonymity cheat behavior in e-commerce can be kept away by the digital certification, so the idea of the combination of online reputation system and digital certification is proposed. The common goal of the reputation system and digital certification is to strengthen the security of network and to reduce the risk of e-commerce. So the reputation system is the important supplement to cryptography technology.
