[In this chapter, the context and the fundamental concepts of physical layer security are well introduced. It starts at Shannon’s definition of information-theoretic security, Wyner’s wiretap model, and secrecy conditions. Then the secrecy metrics are described, including secrecy capacity/rate,...
[In this chapter, we discuss the physical layer security in stochastic geometric networks. We first present the randomness of cellular networks deployment, and summarize the challenges to solve the physical layer security issue. We then introduce some primary knowledge of stochastic geometry...
[In this chapter, we discuss the physical layer secrecy transmission in a downlink cellular network under TDMA, coexisting with randomly located eavesdroppers. We adopt and investigate a secure multi-antenna transmission scheme in which artificial noise is injected into the null space of the...
[The heterogeneous cellular network is believed to be a promising deployment of cellular networks in 5G. This chapter comprehensively studies physical layer security in a multitier HCN where BSs, authorized users and eavesdroppers are all randomly located. We first propose a truncated average...
[In this chapter, we study the benefits of full-duplex (FD) receiver jamming. It enhances the physical layer security of a two-tier heterogeneous wireless ad hoc network, in which each tier is deployed with a large number of pairs of a single-antenna transmitter and a multiple-antenna receiver....
[This chapter concludes the whole book and also provides some future research directions.]
