建立在Internet之上的电子商务以其高效率、低开销、高收益和全球性的特点,得到了很多国家政府和企业的重视,随着Internet的普及而迅速发展。电子商务中最关键的是电子支付系统,为保证数据的安全传输,可采用标准电子支付安全协议。目前,国际上主要有两种通行的安全协议:SSL协议和SET协议。 安全电子交易SET(Seeure Electronic Trade)协议是由MasterCard和Visa公司设计的基于消息流的协议,它用于保证公共网络上银行卡支付交易的安全性。SET提供了多层次安全保障,但它以牺牲简便性换来安全性,所以SET由于高度复杂且价格昂贵影响了具体实施。
E-commerce built on the Internet has attracted the attention of many governments and enterprises in many countries due to its high efficiency, low overhead, high revenue and global characteristics. With the popularization of Internet, it has developed rapidly. E-commerce is the most crucial electronic payment system, in order to ensure the safe transfer of data, the standard electronic payment security protocol can be used. At present, there are mainly two popular security protocols in the world: the SSL protocol and the SET protocol. The Secure Electronic Transaction (SET) Seeure Electronic Trade (SET) protocol is a message flow-based protocol designed by MasterCard and Visa Inc. to ensure the security of bank card payment transactions on public networks. SET provides multiple levels of security, but it comes at the expense of simplicity in exchange for security, so because of the high complexity and high cost SET affected the implementation.
