dc.description.abstractThe 5G technology will bring in a very close future, several new improvements to mobile communication systems, namely in terms of bandwidth, latency and scalability, as well as opening doors to new concepts and techniques. All of this makes 5G a serious candidate to be used in new areas and contexts where mobile communications are not usually used. One of these contexts is the Critical Systems. Given it's strict performance requirements (very low latency, high number of nodes), mobile communications like 4G/LTE, were not a feasible solution on these environments, leading to the need of deploying dedicated closed networks, what comes with increased cost. Some of these areas are railway signalling and power distributions systems. Shifting such systems to 5G networks means that systems usually using closed and dedicated transmissions systems will be using open ones. Moreover, current protocols used on such areas may not contain security mechanisms to prevent cyber attacks on open systems. With this in mind, this research work addresses the security gap existing on protocols and critical systems, namely on railway signalling and power distribution, that the shift to 5G technology will create. We analyse the design of several solutions already being used, as well as other work already developed on security mechanisms to these systems. We propose, develop and evaluate a solution based on a bridging device and an expandable security library, containing several recommended security mechanisms for Critical Systems using the Power Distribution Systems as practical use-case.This thesis is integrated in the 5G Mobilizer Project developed at the Centre for Informatics and Systems of the University of Coimbra, whose goal is to research, develop and validate a set of products running over 5G networks. The outcome of this work, will be integrated on the 5G Mobilizer project, more precisely on PPS3 - Products and Services for Machine-to-Machine communications, providing a security library and a bridging device implementation, combined to act as a Security Box to Critical Systems compliant with strict performance requirements.eng
