Mobile Ticketing System Employing TrustZone Technology.

Research output: Contribution in Book/Report/Proceedings - With ISBN/ISSNConference contribution/Paperpeer-review



Security in mobile commerce is becoming more important due to increasing demand from users wishing to perform online transactions over mobile devices. Security is one of the critical issues for successful adoption of mobile commerce both from an operator and user perspective. Although there are many aspects relating to security in this paper we concentrate on one of the current difficulties concerned with the provision of mobile receipt. Current systems depend entirely on the merchant providing the proof of purchase relating to a particular item or service and many users can experience difficulty if the system fails. Further, as current mobile devices do not offer any verifiable security over the data stored means that merchants can have little confidence in receipts stored on the device. In this paper we present a simple mobile receipt system that offers security both for customer and merchant based on the new TrustZone Architecture for ARM devices.
