电子现金支付系统

与Maitland方案相比，我们的协议具有更少的模运算量和通信量，签名长度也较短，从而更适用于构建离线电子现金支付系统。

In contrast with the protocol provided by Maitland , not only the modular computation overhead and traffic in ours are reduced dramatically , but also the length of signature becomes even shorter , thus ours protocol is more suitable for constructing e-cash payment than Maitland ' s.

离线电子现金支付系统以其匿名性、离线性、独立交易性等特点，成为电子支付系统的首选模型。

The off-line electronic cash payment system has become the priority in the e-payment system due to its merits of anonymity and off-line .
