Conclusions

In this book, we have explored the critical need for robust security in power line communications (PLC) and PLC’s role in our interconnected power grid infrastructure. We also highlight physical layer security (PLS) as a crucial approach for securing low-complexity device networks in PLC applications. While the initial chapters lay a foundational understanding of the PLC ecosystem, discussing its evolution, technological landscape, and significance, subsequent chapters frame channel characteristics and address various security challenges, introducing the concept of PLS as a transformative approach to safeguarding data transmission. From Chaps. 5 – 10 , the focus shifts to detailed methodologies, performance metrics, and practical implementations that enhance the security at the physical layer. Despite extensive research and proposed solutions, the book cannot but conclude with a call for further investigation into securing PLC networks. We also suggest future directions for research with actionable impact that could support broader domains such as the Internet of Things (IoT) and edge computing, highlighting the dynamic and evolving nature of the field.
