Context-based secure resource access in pervasive computing environments

Abstract

We present a system architecture for supporting ubiquitous computing for mobile users across different environments by transparently performing context-based discovery and binding of resources. A ubiquitous computing environment is viewed as a collaboration space among mobile users, system services, and sensors/resources embedded in the physical environment. We present here different policies for binding resources to names in this space. We also present a role based specification model for defining activities.
