|Abstract: ||As the rapid evolution of Internet application, E-Commerce is playing a more and more
significant role. However, small value transaction through the Internet has still not yet got very
popular despite its urgent need.
With an efficient micropayment protocol, small-value transactions on web services can
be developed in a better condition. A key aim of this study is to design an efficient
micropayment protocol with highly secure, low costs and effective features. The payment
scheme will be designed with a balance between security and features and transaction costs.
An efficient micropayment protocol is proposed, which is based on the Peppercoin 
scheme. Our scheme inherits not only the low protocol cost benefit, but also resolves many of
the major limitations of general micropayment schemes.
With this protocol, a great amount of processing costs can be reduced. In addition, the
number of digital signature operations required can be greatly reduced by sharing a vendor
signature within a time interval. Also, session-based serial numbers, which are maintained by
Vendor, resolve the problem of sequential serial number maintained by every Client in
Peppercoin ; at the same time, it still guarantees that consumers who are billed for exactly
the amount they spend.
In order to implement the newly designed protocol, a web service prototype which
collects small value payments for services provided through the Internet, for example, the
viewing of a set of news articles, will be built.
In all, the new protocol not only is highly secure and easily compatible with existing
payment mechanisms such as credit cards, but also can be implemented in an easy-to-use
