“…On the other hand, high quality of Service (QoS) is provided by the convergence of heterogeneous networks (HetNets). They usually involve different access technologies such as macrocell, microcell, femtocells, and attocell, consisting of RF and optical wireless-based networks [78], [79], [80]. Since hybrid VLC/RF systems have both VLC and RF components altogether in the system, physical layer security for such systems should be jointly investigated due to the broadcast nature of both technologies [81].…”

The sixth generation (6G) of mobile network will be composed by different nodes, from macro-devices (satellite) to nano-devices (sensors inside the human body), providing a full connectivity fabric all around us. These heterogeneous nodes constitute an ultra dense network managing tons of information, often very sensitive. To trust the services provided by such network, security is a mandatory feature by design. In this scenario, physical-layer security (PLS) can act as a first line of defense, providing security even to low-resourced nodes in different environments. This paper discusses challenges, solutions and visions of PLS in beyond-5G networks.

“…A novel scheme for inducing inter symbol interference at the eavesdropper was proposed and analyzed in [21]. Further work in [22] presented a novel spatial constellation design strategy based on generalized space shift keying, for PHYSec improvements in MU-MIMO communication systems. In [23] a new secure transmission strategy, which jointly applies generalized precoding-aided spatial modulation and rotating symbol modulation for improving PHY-Sec was proposed.…”

Rate Splitting Multiple Access (RSMA) relies on multi-antenna rate splitting (RS) at the transmitter and successive interference cancellation (SIC) at the receiver. In RS the users' messages are split into a common message and private messages, where the common part is first decoded by the all users, while the private part is decoded only by the intended user using SIC technique. This split of the users' signals into common and private parts raises some interesting tradeoffs between maximizing sum rate versus secrecy rate. In this work we consider the secrecy performance of RSMA in multi-user multiple-input single-output (MU-MISO) systems, where secrecy is defined by the ability of any user to decode the signal intended for user k in the system. To that end, new analytical expressions for the ergodic sum-rate and ergodic secrecy rate are derived for two closed-form precoding techniques of the private messages, namely, 1) zero-forcing (ZF) precoding approach, 2) minimum mean square error (MMSE) approach. Then, based on the analytical expressions of the ergodic rates, novel power allocation strategies that maximize the sum-rate subject to a target secrecy rate for the two precoding schemes are presented and investigated. Our Monte Carlo simulations show a close match with our theoretical derivations. They also reveal that, by tuning the split of the messages, our power allocation approaches provide a scalable tradeoff between rate benefits and secrecy.
