Authentication and Billing Framework for Service Oriented Architecture

The current business environment has become still more demanding in which organizations are under increasing pressure not only to increase revenue but also to respond quickly to changing market conditions. These organizations shall only be successful if they transform themselves and adapt on demand businesses paradigm. There is constant demand for innovation and shorter time to market for products and services. All this has led to newer software engineering paradigms of Service Oriented Software Engineering (SOSE),Software as a Service (SaaS) & Service Oriented Architecture(SOA). These paradigms come with associated security risk.This paper presents a frame work wherein authentication of the clients and billing of services used by client is carried out.In order to mitigate the security risks, our proposed architecture changes the key within a time period which is less than the minimum successful brute force time of our encryption algorithm.
