Outline of Final Research Achievements

This project aims at proposing an endorsement based mobile payment system that can be used by people in disaster areas to buy goods from merchants even without online connection to bank servers. This payment system utilizes mobile ad hoc networks formed from smart phones for communication, thus could be rapidly constructed and robust to node failures in aftershock of earthquakes. Specifically, we proposed schemes for user authentication, preventing collusion and double-spending attacks. We also proposed a monitoring scheme to secure packets route against Byzantine attacks in mobile payment systems and an adaptive packet transmission algorithm that saves battery power of smart phones. We verified by simulations that 1) our endorsement based mobile payment system achieves high transaction completion ratio, 2) our monitoring based link state routing protocol can guarantee secure transactions in mobile payment system.
