摘要: PayWord协议出于对效率和成本的考虑,对于支付公平性方面缺乏支持。基于PayWord协议提出了一个新型的公平支付方案,通过在PayWord协议中引入同时生效签名对消费者的支付承诺提供保护,并且设计了模糊商品服务承诺对商家提供保护,从而提高了PayWord协议的公平性。由于方案避免使用公开密钥算法,因而在保证支付的公平性的基础上还兼顾了支付效率。

Abstract: In consideration of efficiency and cost, PayWord protocol lacks fairness. A new solution based on PayWord protocol was proposed to protect the payment commitment of consumer and the service commitment of provider with concurrent signature, so as to enhance the fairness of PayWord protocol. The analysis results show that the new solution can better meet the requirements of micro-payment for efficiency and fairness.

Key words: concurrnet signature, micro-payment, PayWord, fairness
