TOP LOC 242023 Physical Layer Security

Welcome to the course on "Context-Aware Physical Layer Security for Future Wireless Networks" offered in cooperation with the Medipol University in Istanbul / Turkey.

In this rapidly evolving era of wireless communications and sensing, ensuring the security of wireless networks is of paramount importance. Traditional security mechanisms often rely on cryptographic methods, but they may fall short in addressing the challenges posed by modern and dynamic wireless environments. This course delves into the innovative concept of physical layer security (PLS), where the unique attributes of the wireless channel and wireless signals are harnessed to enhance the security of communications.

Join us on this enlightening journey as we uncover the fusion of wireless communication and context-aware security and equip ourselves to shape the security landscape of future wireless networks. By the end of this course, you will be well-prepared to contribute to the development of secure and resilient wireless communication and sensing systems.
