Physical Layer Security in Ultra-dense Networks
Haijun Zhang, Jemin Justin Lee, Tony Q. S. Quek, I Chih‐Lin · Cambridge University Press eBooks · 2020
This chapter studies the potential of physical layer security in future ultra-dense networks. The unique features of ultra-dense networks are summarized, which can be exploited to enhance the secure transmission at the physical layer. We illustrate that physical layer security can be implemented in many use cases such as vehicle-to-everything, edge computing and caching services, to safeguard the confidential messages. The opportunities and challenges in these research areas are presented.
