一种自可信的匿名公平电子支付协议
Self-trusted anonymous fair-exchange e-payment protocol
摘要
Abstract
In allusion to trust problem in electronic commerce among the customer, the merchant and the third party, we proposed a simple and highly-efficient self-trusted anonymous fair-exchange e-payment protocol in this paper. The protocol was based on Brands off-line electronic cash scheme and concurrent signature. The protocol involved no trusted third party, but could provided a fair commerce environment and made both the customer and the merchant got what to want in time. The analysies and experiment show the protocol satisfied the properties of security, customer-anonymity, accountability, fair-exchange and atomicity besides self-trust, and had fine performance. The protocol has resolved the trouble problems on conspiracy and efficiency in e-commerce. It was suitable for the transaction of large-size items.关键词
