The role of reflective middleware in supporting flexible security policies

Na Xu , Gordon S. Blair , Per Harald Myrvang , Tage Stabell-Kulø and Paul Grace


Next generation middleware must support applications in the face of increasing diversity in interaction paradigms, end system types and network styles. Therefore, to secure applications, security policies must be configured and indeed reconfigured at runtime. In this paper, we propose an approach combining the openness of reflective middleware with the flexibility of programmable security to meet such demands. In particular, we build a security architecture based on the Gridkit reflective middleware platform and the Obol security protocol programming language. The paper then describes a case study that uses flexible policies in order to secure remote procedure calls and secure group communication. We also present the benefits of this approach in terms of flexibility, ease of use and extensibility.
