| 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 p rotected. The solutions may come not only from the ethics education and legislation,but a l so from cryptographic technology.A scheme for privacy protection in the E-comme rce 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 priv acy protection for online customers and prevent the merchant from cheating effic iently; In addition,the scheme also ensure customers dealing with merchants ano nymously. |

| Keywords: | obliviously transfer obliviously polynomial evaluation digital signature anonymo us payment |
