“…To the best of our knowledge, existing work addresses the security of distributed IIoT systems communication, but does not take the low-latency requirements into account. In fact, the cost of securing the communication has already been explored [12], albeit with a strong focus on energy consumption rather than on whether the latency still meets the real-time requirements. It has been found that AES-CBC is most efficient [12], but still significantly more expensive than having no cryptography at all.…”

Fieldbusses have been the backbone of inter-device communication in both industrial and home automation settings for a few decades. The underlying assumption is the availability of reliable and low-latency communication for all busses. This often implies that the busses are confined to a single physical location. With the advent of the 'Internet of Things' (IoT) and succinctly the 'Industrial Internet of Things' (IIoT) and the increased demand for control logic to be pushed into the 'Cloud', that assumption can no longer be upheld. Since no (I)IoT protocol exists to provide remote control, let alone in a secure fashion, while providing low latency at the same time, we are left with the problem of routing fieldbusses from, say, data-centres to shopfloors. This presents a challenge, because those busses have been designed for safety rather than security.In this paper, we elaborate on the viability of routing layer two fieldbus traffic while providing both: low latency to fulfil real-time requirements and security through cryptographic tunnels. We design and implement a network topology where Profinet traffic is routed through a VXLAN over Wireguard overlay to control a SoftPLC instance. We evaluate our implementation in a realistic test-bed and our measurements indicate that bridging Profinet over VXLAN and Wireguard induces a latency low enough for running time-critical applications.

Smart grid is a new revolution in the energy sector in which the aging utility grid will be replaced with a grid that supports two-way communication between customers and the utility company. There are two popular smart-grid reference architectures. NIST (National Institute for Standards and Technology) has drafted a reference architecture in which seven domains and actors have been identified. The second reference architecture is elaborated by ETSI (European Telecommunications Standards Institute), which is an extension of the NIST model where a new domain named distributed energy resources has been added. This chapter aims at identifying the use of IoT and IoT-enabled technologies in the design of a secure smart grid using the ETSI reference model. Based on the discussion and analysis in the chapter, the authors offer two collaborative and development frameworks. One framework draws parallels' between IoT and smart grids and the second one between smart grids and edge computing. These frameworks can be used to broaden collaboration between the stakeholders and identify research gaps.
