A Mobile Payment System Utilizing MANETs for A Disaster Area

Babatunde Ojetunde (1351116)

Existing payment systems require communication infrastructures (like wired networks and cellular networks) to enable transactions in disaster areas, which may be destroyed during disasters (like large-scale earthquake and flooding) and thus cannot be relied on in a disaster area. Therefore, an infrastructureless payment system is essential to for people to buy necessities such as groceries, clothing, and medical supplies.

In this thesis, we propose a mobile payment system, adopting infrastructureless mobile ad-hoc networks (MANETs), which allows users to shop in disaster areas while providing secure transactions. Specifically, we propose an endorsement-based scheme to guarantee each transaction and a location-information based scheme to provide transaction monitoring, and thus achieve transaction validity and reliability. Our mobile payment system can also prevent collusion between two participating parties, reset and recover attacks from any user and double spending by using location-based mutual monitoring by nearby users.
