“…Then, the uncertainties of legitimate channels can also be characterized by the three methods mentioned above. It is worth noting that, towards the uncertainties of real channels, the robust secure designs are commonly performed to ensure achieving the security, reliability, and robustness of information transmission [30], [39], [56], [234], [253], [275].…”

Due to the malicious attacks in wireless networks, physical layer security has attracted increasing concerns from both academia and industry. The research on physical layer security mainly focuses either on the secrecy capacity/achievable secrecy rate/capacity-equivocation region from the perspective of information theory, or on the security designs from the viewpoints of optimization and signal processing. Because of its importance in security designs, the latter research direction is surveyed in a comprehensive way in this paper. The survey begins with typical wiretap channel models to cover common scenarios and systems. The topics on physical-layer security designs are then summarized from resource allocation, beamforming/precoding, and antenna/node selection and cooperation. Based on the aforementioned schemes, the performance metrics and fundamental optimization problems are discussed, which are generally adopted in security designs. Thereafter, the state of the art of optimization approaches on each research topic of physical layer security is reviewed from four categories of optimization problems, such as secrecy rate maximization, secrecy outrage probability minimization, power consumption minimization, and secure energy efficiency maximization. Furthermore, the impacts of channel state information on optimization and design are discussed. Finally, the survey concludes with the observations on potential future directions and open challenges.

“…Optimising the code-word transmission rate in the previous study, 21 a larger feasible set in connection with the outage constraints determined for the MIMOME transceiver was essentially achieved. Locality or globality-driven procedures: In the previous study by Ma et al, 22 a relaxation-restriction method was presented that was significantly able to achieve near-optimal solutions. In the previous study by Shi et al, 23 globally optimal solutions were accurately achieved regarding SDR.…”

The paper first provides a general overview on the existing probabilistic‐driven methods aimed at convexifying the secrecy rate maximisation problem. Challenges and requirements of the procedures are fully taken into consideration for multiinput multioutput multiantenna eavesdropper wiretap channels. The problem constrained by an outage probability for the pure Ergodic capacity (perfect secrecy defined by Shannon) is analytically solved. Such analytical solution is performed robustly, something that originates principally from our imperfect statistical knowledge of the wiretap channel at the transmitter. Then, solely concentrating on McDiarmid inequality, we also extend our previous work to propose 2 new approaches. The bounds of our represented schemes are obviously accurate, tight, and achievable, something that effectively guarantee the system to overcome the probable challenges, eg, correlation in multiinput multioutput antenna arrays. Furthermore, the procedures are straightforwardly compared with each other from standpoint of complexity. Results are technically conducted to assure us about the proposed methods' merits, merely defining the significantly more favourable asymptotic bounds and the less resultant complexities. In particular, our proposed approaches sensibly outperform all the procedures, per se, something that can be accordingly assigned for other ergodic equilibria.

“…In fact, security is also a fundamental problem in common wireless systems due to the broadcast nature of the wireless medium [36]. The most recent advance in physical (PHY) layer security is to exploit the PHY characteristics of the wireless fading channels for perfect secrecy of communication, especially there are some works have been presented to studied the PHY secrecy of the traditional wireless systems while considering imperfect CSI [37]- [43]. However, none of them is related to SWIPT systems.…”
