Secure mobile payment methods are typically needed in mobile access channels, it is vital toapply them when using mobile payment applications, which have arisen as a result of the increase of e-commerce. Currently, there are some payment methods that most of them can be used when conducting transactions but, they differ in terms of functionality, usability, costs or security. What makes mobile payment system more useful and necessary are the features and functionalities which are essentially based on customer needs that may differ in different market places, social categories and regions. In addition to payment system functionality, what mainly matters is securing payment methods with sufficient security protections. In this thesis, it is been tried to introduce some features currently lacking in mobile payment systems to propose a security architecture and then to present a solution for prospective problems with some current mobile payment systems and applications. The solution mainly implements what has been proposed and required to fulfill system requirements. The proposed security architecture supports already designed mobile payment system (SAFE) which typically interacts with the merchant and the customer for performing secure payment transactions. Mobile payment security architecture is designed, implemented and analyzed to be highly scalable and modular in addition to providing the desired security requirements set to it in this thesis work. The architecture is enhanced with mobile applications, so called SAFE apps, enabling securely authorizing e-commerce transactions. This report begins with introducing mobile payment system technologies, concept and architecture as the foundation for this work. The systems relevant to the one proposed in this thesis are briefly discussed in terms of functionality and security issues. System architecture and design of SAFE Mobile Payment System are briefly discussed as the core component of the settling e-commerce functions in a holistic view. The functionality and security issues ofthe system design and implementation are presented and finally the work is analyzed to determine how the project objectives were met.
