A New Credit Based Micropayment Scheme

As the development of online commercial transactions, the transactions that involve small amount of money are becoming popular. However, the existing micropayment systems are either not efficient enough for micropayment or too complicated and expensive for extensive application. A new credit based micropayment scheme is proposed in this paper. With only reasonable security performance, the efficiency of the scheme gets higher and the implementation is much cheaper, thus it is very suitable for extensive application. With reference to the mature credit card system, a credit mechanism was built in this scheme to achieve the better performance and lower cost. On the other hand, good practicability and strict anonymity are provided.
