SitAC - A System for Situation-aware Access Control - Controlling Access to Sensor Data

This paper addresses situation-aware access control for sensitive data produced in sensor networks. It describes how an attribute-based access control system can be combined with a situation recognition system to create a highly flexible, well performing, and situation-aware access control system. This access control system is capable of automatically granting or prohibiting access depending on situation occurrences and other dynamic or static security attributes. Besides a high-level architecture, this work also describes concepts and mechanisms that can be used to build such a system.
