Abstract

Wireless communications and cellular networks are vulnerable to various security threats due to several reasons. Physical layer techniques and technologies, such as massive multiple-input multiple-output (MIMO), millimeter communications, cognitive radio, and full-duplex wireless, can be easily integrated to implement comprehensive 5G wireless security solutions. This chapter discusses physical layer security techniques for 5G wireless communications. It introduces full-duplex communications and transceiver architecture, and discusses prior art on full-duplex physical layer security schemes reported for the bidirectional, base station, and relay topologies. The chapter considers the optimum beamforming designs for full duplex wireless security solutions for multiantenna bidirectional and relay communication systems. It emphasizes future challenges and open issues for the implementation of full duplex secure transmissions in 5G systems. Due to simultaneous transmissions, full-duplex operation in cellular networks can introduce increased levels of co-channel interference.
