Security and privacy threats in IoT architectures

In this paper, we describe an overall architecture for Internet of Things (IoT) and analyze the known and new threats for the security, privacy and trust (SPT) at different levels of architecture, with attacker centric and system centric approaches. Our strong view is that IoT will be an important part of the global huge ICT infrastructure (“future Internet”) humanity will be strongly relying on in the future. While it is globally connected, it is divided into millions of management domains, such as homes, smart cities, power grids, access points and networks, etc. It will evolve both bottom-up and top-down. An important question is what consequences a bottom-up and top-down construction of the IoT infrastructure has for the security, privacy and trust. Another dimension is the energy consumption of IoT and its relationship with the architecture and SPT. These are research issues.
