“…So far, communication security has been provided by using cryptography methods. Recently, an alternative technology, physical layer security (PLS) has been proposed to address the security problem of wireless systems in the physical layer by using the randomness of the wireless channels [10]. PLS is the most recent and easy to use security performance concept that can be used in NTNs [11], [12].…”

In the next generation (6G) wireless networks, the integration of terrestrial and non-terrestrial networks is essential to provide flawless connectivity over the globe. The vital element of this architecture is the high altitude platform station (HAPS) systems, which can provide reliable and ubiquitous connectivity among satellites, unmanned aerial vehicles (UAVs), and terrestrial users. Motivated by the importance of HAPS systems, in this paper, we provide three different use-cases for HAPS eavesdropping scenarios and investigate their physical layer security (PLS) performances. To quantify the PLS performance of the proposed setups, we perform secrecy outage probability (SOP), probability of positive secrecy (PPSC), average secrecy capacity (ASC), and secrecy throughput (ST) analyses. Furthermore, we also provide important design guidelines that can be beneficial for secure HAPS systems.

“…Typically, communication security is guaranteed through encryption. In recent research, however, a physical layer security (PLS) has been considered as a relevant solution complementary to cryptographicbased schemes to secure information against eavesdroppers relying on channel characteristics [7]. In particular, PLS has been introduced for FSO communication [8]- [10].…”

In recent years, satellite communication (SatCom) systems have been widely used for navigation, broadcasting application, disaster recovery, weather sensing, and even spying on the Earth. As the number of satellites is highly increasing and with the radical revolution in wireless technology, eavesdropping on SatCom will be possible in next-generation networks. In this context, we introduce the satellite eavesdropping approach, where an eavesdropping satellite can intercept optical communications established between a low Earth orbit (LEO) satellite and a high altitude platform station (HAPS). Specifically, we propose two practical eavesdropping scenarios for satellite-to-HAPS (downlink) and HAPS-to-satellite (uplink) optical communications, where the eavesdropper satellite can eavesdrop on the transmitted signal or the received signal. To quantify the secrecy performance of the scenarios, the average secrecy capacity (ASC) and secrecy outage probability (SOP) expressions are derived and validated with Monte Carlo (MC) simulations. We observe that turbulenceinduced fading significantly impacts the secrecy performance of free-space optical (FSO) communication.
