Securing and managing large-scale shared Internet of Things Infrastructures by Policy Definition and Enforcement

The Internet of Things (IoT) trend shows the pervasiveness of computing and introduces an online component to many aspects of human life. However, security needs to be taken into account to ensure widespread adoption of such technology, especially since IoT directly connects the physical and virtual world. Furthermore, to unlock the full potential and economies-of-scale, multiple stakeholders must be integrated and devices must be shared between applications. This PHD will focus on security in such a shared multi-stakeholder Internet of Things platform. The core activities will include: (i) research on a platform with explicit distinction between infrastructure providers and end-users of the shared infrastructure, (ii) research which policies are appropriate for expressing specific classes of security and management requirements for the various subsystems of the platform, and (iii) research how to effectively enforce each of those classes of policies at the platform level.
