Internet of Things (IoT) Enabling Technologies, Requirements, and Security Challenges

Internet of Things (IoT) is an emerging technique for connecting heterogeneous technologies related to our daily needs that can affect our lives tremendously. Many architectures and applications have been proposed and implemented using IoT platform from a simple supply chain to complex life support systems. There are many obvious benefits of such networks but these systems can cause great danger to finance and life if compromised. Such issues are hindering the mass adaptation of IoT. This requires a strong architecture that can provide strong user authentication, access control as well as privacy and trust to the users of the system. The IoT network is a heterogeneous network connecting many small hardware constraint devices and also where traditional security architectures and techniques cannot be applied. Therefore, it requires a different set of specialized techniques and architecture to provide security to the IoT network. This paper focuses on the security requirements, current state of art as well as future directions in the field of IoT.
