摘　　要：随着电子商务的迅速发展和普及,电子商务安全支付显得越来越重要,成为影响电子商务发展的关键技术。以国际电子商务支付协议标准SET协议为研究对象,针对其无法确保商品原子性和确认发送原子性的缺陷,进行了一些改进;建立了一个基于四方的、能够自动存取关键电子证据、确保商品原子性和确认发送原子性、仲裁处理交易纠纷的安全电子商务支付协议;给出了协议的形式化描述;最后对基于四方的电子商务支付协议的安全性进行了分析。With the rapid development and popularization of electronic commerce,the secure payment in the area has become more and more important and is a key technology that impacts on the development of e-commerce.Aiming at the standard Secure Electronic Transaction protocol（SET）,some improvements were done for the SET protocol in order to assure the goods atomicity and certified delivery.Then,this paper proposed a secure e-commerce payment system based on the four parties that can not only support the goods atomicity and certified delivery,but also access the key electronic evidence automatically and deal with the transaction disputes.In the meantime,the formal description of the protocol is presented.Finally,the security of the proposed protocol was compared and analyzed.
