Abstract

The issue we have focused on in the broad area of security for Pervasive Computing is maintaining trust in an interactive environment. Our solution is based on the premise that computers and implicit interaction mechanisms must function in accordance with the explicit parameters of physical human-human interaction. Otherwise, this results in imbalances between the physical and virtual worlds, which leads to ”windows of vulnerability”. Our solution presented requires an infrastructure of pervasive and context sensing technology, to provide entity mapping, policy and trust management services. We also investigate generating cryptographic keys using the context available The underlying technology is based on the Smart-Its context sensing, computation and communications platform.
