Abstract

There is an increasing demand for variability and dynamic customization of middleware. Security, a key middleware service, requires variations at design-time, deploy-time as well as runtime. This is hard to achieve with state-of-the-art middleware. To handle this problem, we applied an SPL approach based on static and dynamic AO-composition in a component-based middleware platform. As proof of concept we developed a prototype with several variations in the security domain. A first evaluation shows that AO and component-based middleware are promising technologies to obtain an SPL.
