Security requirements for environmental sensing technology

In this paper, we identify security objectives and requirements for a class of ubiquitous computing technology, namely environmental sensing infrastructure. The method used starts with analyzing scenarios to define user-driven security objectives for specific applications and identify hints to potential misuse in a realistic setting. The described applications are examined to understand how they could be built using existing sensing technology (TinyOS, InCA and the Context Toolkit are considered here). The resulting security requirements, related to technical, social and legal issues, drive the discussion about the features and shortcomings of the considered sensing technologies and aid in proposing suggestions for enhancing their security properties.
