Industrial Internet of Things (IIoT) is evolving as the future of Cyber-Physical Systems (CPS). The
introduction of the IIoT systems aims to optimize efficiency and operability utilizing complex data
analytics. The IIoT requires constant bidirectional communication with cloud services and results in
internet exposure of these cyber-physical systems which raised a lot of security issues. Bidirectional
communication enables the remote control of the infrastructure mechanisms and thus support efficient
management of cyber-physical systems. However, remote communication with critical CPS also raises
security concerns, such as assuring user authentication when performing critical operations. The purpose
of this thesis is to study and propose an approach of Multifactor User Authentication on the edge side of
CPS. Towards these directions, in this thesis we design and implement an Edge OTP (One Time
Password) authentication for critical CPS operations, as a Multi-Factor Authentication (MFA) when a user
attempts to control these systems. We analyze and perform two scenarios based on Smart Buildings and
Industrial IoT indicating that this approach can be adopted in all IIoT domains as an extra security
measure that enhances the overall cybersecurity of these critical systems.
