Paper Abstract:
|
The micropayment has a special position in mobile commerce (m-commerce). Micropayment systems allow payments with low values. In these systems amount of payments are very low so implementation of security is limited to necessity. One of the problems which is considerable in Payword base micropayment systems is that users have to create a new payword chain for each vendor. MVPayword system is an extension to Payword which make it possible for users to buy from various vendors using only one hash chain. According to the fact that nowadays many people use mobile device for purchases, in this paper we propose a model for using MVPayword in m-commerce. This model provides anonymity for customers against vendor and broker. Indeed it prevents mobile users (MUs) to do double-spending and it can prevent inventing and stealing Paywords. Moreover this model prevents MUs from spending more than credit and it prevents MU fraud and NO fraud. |
