摘要

电子商务中需要尽可能地保护用户隐私

而密码技术则是这一需求的重要保障.在安全的1/2不经意传输存在这一假设下

本文提出了一个安全且具隐私保护的数字产品网上交易方案.方案很好的考虑了实际交易中可能出现的情况

并针对可能出现的种种欺诈行为(如:商家以次充好

买家一次消费多次交易等问题)给予了有效的解决.同时结合匿名支付和匿名通信技术保证了用户交易的匿名性.

Abstract

It is well known that customers' privacy in electronic commerce should be well protected.The solutions may come not only from the ethics education and legislation

but also from cryptographic technology.A scheme for privacy protection in the E-commerce is proposed which is based on the existence of secure 1/2 oblivious transfer.It takes oblivious polynomial evaluation as its technical means to realize privacy protection for online customers and prevent the merchant from cheating efficiently; In addition

the scheme also ensure customers dealing with merchants anonymously.
