Abstract
The evolution of wireless networks and mobile device technologies has increased concerns about performance and security of mobile systems. We propose a new secured applicationlevel architecture for a two-party mobile payment transaction that is carried out between a resource-limited mobile device and a resource-rich computer server over wireless networks. As an example of such transactions, the mobile banking transaction is focused on throughout this thesis. The proposed architecture, namely SA2pMP, employs a lightweight cryptography scheme (combining both a Public-key cryptography algorithm (ECDSA) and a Symmetric-key cryptography algorithm (AES)), a multi-factor authentication mechanism, and a transaction log strategy. The proposed architecture is designed to satisfy the four properties of confidentiality, authentication, integrity and non-repudiation that are required by any secure system. The architecture can be implemented on a Java ME enabled mobile device. The security API library can be reused in implementing other two-party mobile applications. The present study shows that SA2pMP is a unique lightweight security architecture providing comprehensive security for two-party mobile payment transactions. In addition, simulations demonstrate that SA2pMP can be installed in resource-limited mobile devices as a downloadable software application. The main contribution of the thesis is to suggest a design for a security architecture for two-party mobile payment transactions, for example, mobile banking. It suggests a four-layer model of mobile payment participants, based on Karnouskos (2004). This model clarifies how participants are involved in a mobile payment transaction. In addition, an improved model is suggested to guide security aspects of system design, which is based on an Onion Layer Framework (Wei, C.Liu, & Koong, 2006).
