Abstract

In this paper, particular study of security of ground-to-unmanned aerial vehicle (UAV) communication link, on physical layer, in the presence of a ground eavesdropper is given. We characterize the UAV as data collector, which is distributed randomly in a horizontal plane of certain cylindrical region, while a ground user that sends data up to UAV, is located in the centre of cylinder's base. Furthermore, we assume that the eavesdropper is randomly located within a circle which defines the base of the cylindrical region. The main (user-to-UAV) channel is characterized as severely corrupted by the path loss effect, while the wiretap (source-to-eavesdropper) channel is subjected to Fisher-Snedecor fading. Under aforementioned system/channel scenario, the probability of intercept events is investigated. In more details, throughout numerical results, the impact of the predefined cylinder's height and its base's radius, as well as the impact of the fading depth and shadowing severity of the ground wiretap channel, on the intercept probability, is analysed. Related concluding remarks are also given.

Physical Layer Security for UAV-Assisted IoT Data Collection in the Presence of an Aerial Eavesdropper

Jelena A. Anastasov, Aleksandra M. Cvetkovic, Aleksandra S. Panajotović +3 more

In this paper, we study physical layer security of an unmanned aerial vehicle (UAV)-assisted communication system, where a UAV collects data from a sensor node and UAV-eavesdropper tends to overhear confidential information. In particular, assuming Fisher-Snedecor fading environment, we derive the closed-form expression of the intercept probability and we examine the effect of different system/channel parameters on this performance metric. Numerical results are also presented to verify analytical result; and to highlight the impact of specific fading/shadowing conditions over the main-UAV link and UAV-eavesdropper’s link, as well as the impact of UAVs’ positions.

Safeguarding UAV IoT Communication Systems Against Randomly Located Eavesdroppers

Hongjiang Lei, Di Wang, Ki‐Hong Park +4 more

Unmanned aerial vehicles (UAVs) will be extensively utilized in various Internet of Things (IoT) scenarios due to their flexible mobility and rapid on-demand deployment. It becomes necessary and urgent to investigate the secrecy performance of the UAV IoT communication systems because of the open characteristics of wireless channels. In this article, the physical layer security of UAV IoT communication systems is studied, in which a ground IoT device transmits some confidential messages to a UAV hovering in the air, while a random number of eavesdroppers are randomly positioned around the ground source. The ground-to-air channel is assumed to experience Rician fading for the case of line-of-sight propagation and Rayleigh fading for the case of nonline-of-sight propagation, respectively. In addition, in order to improve the security of the system, we also investigate the secrecy performance of the UAV IoT system with a friendly UAV that generates jamming signals to distract the eavesdroppers. Utilizing the stochastic geometry theory, the cumulative distribution functions for the signal-to-interference-plus-noise ratio of the main and eavesdropping links are derived, and then the analytical expressions of the secrecy outage probability and the average secrecy rate are obtained. Finally, the accuracy of the analytical results is verified by Monte Carlo simulation.

It becomes necessary and urgent to examine the secrecy performance of the UAV communication systems due to the open characteristics of the transmission technologies employed in UAV systems. In this paper, we investigate the physical layer security of the UAV communication system, in which the ground base station sends secret messages to the UAV hovering in the air, while a random number of eavesdroppers are randomly located around the ground base station. Using the Poisson point process theory, we obtain the exact and approximate expressions of the cumulative distribution function for the signal-to-noise ratio of the ground-to-air link, and then the analytical expressions of the secrecy outage probability and the average secrecy rate are derived. Finally, the accuracy of the analytical results is validated by Monte Carlo simulation.

Physical Layer Security Over UAV-to-Ground Channels with Shadowing

Remon A. Polus, Claude D’Amours, Burak Kantarcı

With the notable interest in unmanned aerial vehicle (UAV)-to-ground communications, new fading channel models that take into account the effects of shadowing have been proposed for beyond 5G networks. Guaranteeing physical layer security of the UAV-to-ground channels is essential for the transmission of confidential messages in the presence of an eavesdropper. In this paper, we examine physical layer security metrics, such as the average secrecy capacity, the secrecy outage probability, and the probability of strictly positive secrecy capacity, in UAV-to-ground communications with shadowing. Monte Carlo simulations are performed to verify the analytical expressions. Finally, the effect of the fading parameters on the system performance is studied.

Secrecy performance analysis of unmanned aerial vehicles in the presence of interference

Abhijeet Upadhya, Vishal Narain Saxena

Abstract In this research work, we study the secrecy performance of Unmanned aerial vehicles (UAVs) in the vicinity of an interfering and eavesdropping UAVs. More precisely, firstly a case when the ground user communicates with the intended UAV where two unwanted UAVs operate in the vicinity, has been investigated. It is also considered that the wiretapping UAV also suffers interference from different UAV. The modelling of the UAV communication system considers the impact of small-scale fading, line-of-sight (LoS) probability, altitude and 3D coordinate of all the three involved UAVs. To this end, analytical expression has been derived for the secrecy outage probability (SOP) for the system considering simultaneous effects of eavesdropping and interference. The analysis for secrecy capacity has also been conducted to derive analytical formula. The results are extended to a case when multiple interfering and eavesdropping UAVs function to derive the expression for the SOP. Importantly, the numerical simulation of the derived results show that the effect of eavesdropper can be minimized by placing an interferer in the vicinity of the wiretap source. Moreover, the impact of power transmitted during wiretapping by the eavesdropper appears to be more compared to distance from intended UAV.

Secrecy Outage Performance Analysis of UAV-Assisted Relay Communication Systems With Multiple Aerial and Ground Eavesdroppers

Tingnan Bao, Haiming Wang, Wenjing Wang +2 more

In this article, we study the secrecy performance of an unmanned aerial vehicle (UAV)-assisted relay communication system, where a ground base station (GBS) intends to send confidential information to the ground legitimate user Bob with the help of a UAV relay in the presence of multiple aerial and ground eavesdroppers. We consider the height-dependent probabilistic line-of-sight and the general$\kappa$-$\mu$shadowed channel fading model in the system. To enhance the secrecy performance, the GBS and UAV relay apply directional beamforming transmission while implementing protection zones around their intended receiving destinations. We then derive the approximate closed-form expressions of the secrecy outage probability (SOP) under different aerial and ground eavesdropperscolluding strategies. To get insights, we also obtain the SOP expression over Rayleigh fading as a special case. After discussing the impacts of transmitting and multiple aerial and ground eavesdropping parameters on the SOP, we show that the optimal altitude of UAV relay exists with the minimal SOP value under different urban environments. We also show that UAV eavesdroppers have a larger effect on the system performance than ground eavesdroppers.
