“…Therefore, we assume that signals are transmitted through one cluster and all the AODs of paths are distributed within the angular range [θ min , θ max ]. If Ψ i ∈ [sin(θ min ), sin(θ max )], the i th column of U (the i th orthogonal basis vector) represents a spatially resolvable path and we assume that the i th complex gain g i is a complex Gaussian coefficient with g i ∼ CN (0, 1); otherwise, g i = 0 [4], [24], [30].

Millimeter wave offers a sensible solution to the capacity crunch faced by 5G wireless communications. This paper comprehensively studies physical layer security in a multi-input single-output (MISO) millimeter wave system where multiple single-antenna eavesdroppers are randomly located. Concerning the specific propagation characteristics of millimeter wave, we investigate two secure transmission schemes, namely maximum ratio transmitting (MRT) beamforming and artificial noise (AN) beamforming. Specifically, we first derive closed-form expressions of the connection probability for both schemes. We then analyze the secrecy outage probability (SOP) in both non-colluding eavesdroppers and colluding eavesdroppers scenarios. Also, we maximize the secrecy throughput under a SOP constraint, and obtain optimal transmission parameters, especially the power allocation between AN and the information signal for AN beamforming. Numerical results are provided to verify our theoretical analysis. We observe that the density of eavesdroppers, the spatially resolvable paths of the destination and eavesdroppers all contribute to the secrecy performance and the parameter design of millimeter wave systems.Index Terms-Physical layer security, millimeter wave, multipath, stochastic geometry, artificial noise, secrecy outage, secrecy throughput.

Ensuring the physical layer security (PHY-security) of millimeter wave (mmWave) communications is one of the key factors for the success of 5G. Recent field measurements show that conventional fading models cannot accurately model the random fluctuations of mmWave signals. To tackle this challenge, the fluctuating two-ray (FTR) fading model has been proposed. In this correspondence, we comprehensively analyze the PHYsecurity in mmWave communications over FTR fading channels. More specifically, we derive analytical expressions for significant PHY-security metrics, such as average secrecy capacity, secrecy outage probability, and the probability of strictly positive secrecy capacity, with simple functions. The effect of channel parameters on the PHY-security has been validated by numerical results.

This article examines the secrecy performance of millimeter-wave (mm-Wave) communications with imperfect hardware and uncertain eavesdropper (Eve) location. We consider a multiple-antenna source communicating with a single-antenna destination using masked beamforming to transmit the information signals with artificial noise (AN) in the presence of a passive Eve. For this system, we derive new expressions for the secrecy outage probability (SOP) and secrecy throughput with mm-Wave multipath propagation under slow-fading channel conditions and hardware imperfections. Based on this, optimal power allocation (OPA) solutions are derived for the information and AN signals aimed at minimizing the SOP and maximizing the secrecy throughput. Our results reveal that it is non-trivial to achieve an OPA solution for the general scenario of imperfect hardware. We also highlight that our proposed masked beamforming with OPA scheme significantly enhances the secrecy throughput compared with the benchmark schemes of maximal-ratio transmission and equal power allocation.
