摘要: 提出了一个基于Payword的移动微支付协议,新协议对Payword的协议的不足之处进行了改进。为了使协议更好地应用到移动商务中,协议采用了对称加密算法,并且将多值hash链应用到与不同商家的交易中,降低了用户端的存储和计算开销。协议在保证安全性的前提下降低了微支付的交易成本。

Abstract: A Payword-based micropayment protocol is described in this paper. It overcomes Payword’s several shortcomings. In order to make it suitable for m-commerce, only symmetry-encryption is used. Multiple Paywords which reduce customers’ storage and computation can be applied to several vendors. The protocol minimizes the exchange cost of micropayment on the promise of security.

Key words: mobile commerce, mobile payment, micropayment
