摘　　要：在简要分析了当前我国基于帐号的移动支付系统的基础上 ,提出了一种新的基于代币的移动支付系统模型 ,克服了传统模型的不足 ,并给出了适用于此模型的小额电子支付协议 .该支付协议利用电子现金本存储多个电子现金 ,使得电子现金本可多次进行支付直至其中的电子现金用完 ,从而防止了电子现金序列号的迅速增长 .This paper analyzed the account-based mobile payment system and presented a new token-based mobile payment system model overcoming some defects of the former one. A micro-payment protocol for this model was proposed. Instead of the single e-coin defined by Chaum, a specific number of e-coin was stored in a paybook in this protocol. With this method, one paybook can be used for payment many times until e-coins in it were used out to prevent the rapid growth of e-coin′s serial number.
