| Electronic
Payment Systems for tinny amounts. (Micro Payments)
Since last semester, I am working with Micro
Payment systems, which consists of electronic payments mechanisms
for drive small amount trade transactions, like buying the
information of a webpage or for download a mp3-encoded music
file.
The main goal of Micro Payment systems is to
decrease as possible the operational cost involved in each
transaction. The need to use this kind of systems is comming
from the fact that the operational cost for conventional electronic
payment mechanisms are bigger than the amount of the trade
transaction involved in the payment.
There are several already proposed schemes to
drive this kind of payment operations, but there are still
some problems to solve and also the posibility to find new
ones from the proposed schemes.
About this topic is my research at UEC, in OHTA-KUNIHIRO
Laboratory at ICE Department, under the advisoring of Prof.
Kazuo OHTA.
Some interesting notes about the status of this
research are:
- We are working to propose a mechanism to generate a Check
List for the MR3 (Micali- Rivest) Scheme.
- We are implementing the MR2 and MR3 schemes in a web-based
Information Delivering System, using Java platform.
- We are looking for security problems in the MR schemes.
