Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

The Personal Distributed Environment is a new concept being developed within the Mobile VCE Core 3 research programme whereby users have access to their services and data through a distributed set of terminals, wherever their location: ubiquitous access. Devices are co-ordinated by Device Management Entities (DMEs), which are either Local DMEs, controlling devices within a single PDE subnetwork at a user's home or office. For example, or an overall Root DME providing universal co-ordination and a single point of contact. While such a structure allows very flexible service delivery, it has serious security concerns, as the presence of signalling between Root and Local DMEs will allow the location of the user to be determined at all times. In this paper, we analyse the security threats to the DME structure proposed for the PDE, and introduce a system of tunnelling and mix networks to provide security and privacy.
