Secure Spaces: Physically Protected Environments for Information Security

Abstract

We introduce the novel concept of ""Secure Spaces"", physical environments in which any resource is always protected from its unauthorized users' eyes or ears by assuredly enforcing its access control policies for pairs of it and each user inside them. Aiming to build such secure spaces, this paper proposes a model and an architecture for space entry control based on its dynamically changing contents, such as users, physical resources and virtual resources outputted by embedded devices. We firstly formalize the content-based entry control model and mechanism, and then describe the architecture for building secure spaces.
