Secure service-oriented architecture for mobile transactions

The paper describes secure service-oriented architecture for mobile transactions. The architecture comprises components, protocols, applications and interfaces and it provides various security services to various mobile applications: registration, certification, authentication, and authorization of users, secure messaging at an application-level (end-to-end security), protection of data in databases, and security services for protection of its own components. The architecture is modular, integrated, extendible and scalable. The paper describes design of the architecture, the status of its current implementation, and future research and development plans.
