A Context-Aware Security Framework for Next Generation Mobile Networks

The openness and heterogeneity of next generation communication networks are now highlighting more security issues than those of traditional communication environments. Moreover users’ security requirements can often change in mobile communication environments, depending on the situation in which the user is immersed. Our objective is to define a context-aware security framework for addressing the problems of end-to-end security on behalf of endusers. Based on context data acquisition and aggregation features, the framework uses contextual graphs to define security policies encompassing actions at different layers of communication systems’ architecture, while adapting to changing circumstances.
