A New Era for Cyber-Physical Systems: Optimal Integration of AI, ML and Digital Twins

In an era where the interconnection between the digital and physical realms becomes increasingly complex, the security of cyber-physical systems (CPS) emerges as a crucial challenge. This paper undertakes a comprehensive analysis of journal articles on CPS security, examining the diverse methodologies proposed to fortify these systems against emerging threats. Emphasizing the role of advanced technologies such as artificial intelligence (AI), machine learning (ML), and blockchain, our study showcases their pivotal contributions to enhancing CPS resilience. Central to our analysis is the innovative integration of AI and ML with Digital Twins, a strategy that stands out for its ability to concurrently bolster security and operational efficacy. This study gives further detail a novel application of AI-enhanced Digital Twins, outlining a methodology for its practical implementation. Through this investigation, the aim is to enrich the scholarly dialogue on CPS security, advocating for the strategic use of technological advancements to create smarter, safer, and more efficientsystems.
