Objectives
The cyber-physical systems (CPSs) are resulted from the integration and coordination of cyber and physical components. The emergence of the Internet of Things (IoT) has led to a significant growth of CPSs, resulting in a wide range of practical applications in various sectors, including but not limited to mobility and transportation, healthcare, smart homes, and smart grids. Due to the existence of wireless communication links, these systems are vulnerable to cyber-attacks. In recent years, different types of attacks have been generated to damage cyber-physical systems, including DoS, replay, zero-dynamic, and covert attacks. The design of these attacks can be derived from a 3D model that is constructed using three primary sources: model knowledge, disruption resources, and disclosure resources. Several instances of cyber-attacks have occurred in recent years, one notable example being the Stuxnet attack, which was a computer worm specifically designed to inflict significant harm on Iran's nuclear infrastructure, resulting in a substantial setback to their nuclear program for a duration of two years.
Being resilient against cyber-attacks is a crucial step in designing these CPSs. Recently, various strategies to make CPSs resilient to cyber-attacks have been proposed to overcome these problems, including W-MSR and reputation algorithms. Some other algorithms are model-based algorithms, which exploit the tools of robust and adaptive control theory. The utilization of semi-homomorphic encryption presents itself as an additional approach for enhancing the resilience of a CPS against cyber-attacks. Recently, there has been a growing interest in exploring the utilization of blockchain technology as a means to enhance the security and resiliency of CPSs. In this way, the confidentiality of the data is maintained, and the system's resistance to attacks is increased by employing a secure transmission mechanism based on blockchain.
Workshop Plan
In the beginning of this workshop, the notions of cyber-physical systems and cyber-security are defined. Then, the importance of ensuring security in the Industrial Internet of Things (IIoT) is discussed. Afterward, we proceed directly to the corresponding literature on cyber-security in CPSs by introducing various cyber-attacks. In addition, we examine contemporary resilient control strategies, including graph-based, model-based, and encryption-based methods, as well as introduce the novel concept of utilizing blockchain for secure and resilient CPSs. Finally, we turn to the latest research from our team on enhancing security in three key areas, including platoons, microgrids, and networked control systems, and this concludes the first part of our workshop. In the second part of this workshop, we will discuss AI for cyber security and the concept of CyBoK for modern power systems and power electronics-dominated grids (please see the detailed abstract from Dr. Baghaei).
