摘　　要：在电子商务中需要对用户隐私进行保护,根据安全多方计算中的不经意传输协议,运用基于Schnorr签名的不经意电子信封方案提出了一个网上订购数字产品的方案。用户匿名付费给银行后得到银行对欲订购商品的数字签名,用户通过电子签名和商家进行不经意交互,用户只能得到自己订购的商品。算例表明,该方案能够有效地保护用户的隐私信息不被泄露,同时防止商家的恶意欺诈。The privacy of users must be protected in e-commerce According to the theory of oblivious transfer, this paper pro- posed an online order of digital products scheme which could effectively protect the user＇ privacy through OSBE based on Schnorr signature.
