“…Inspired from PLS, the authors in Reference propose an algorithm to minimize the total transmit power in a scenario wherein the legitimate receivers are dispersed throughout multiple beams with each receiver surrounded by multiple passive eavesdroppers. Similarly, Bankey et al investigate the secrecy outage probability of a hybrid multiantenna satellite‐terrestrial relay network in the presence of multiple eavesdroppers. Particularly, the authors employ two classic cooperative protocols, decode and forward and amplify and forward in the presence of both colluding and non‐colluding eavesdroppers.…”

Satellite communication is becoming a complementary technology in future 5G and beyond networks due to its wider coverage. Similar to any terrestrial network, security has become a major concern in satellite networks. Due to a long distance between ground stations (GS) and satellite transponders and due to its inherited broadcast nature, satellite communication encounters certain limitations such as high bit error rate, high link delays, power control, and large round trip delays. The aforementioned limitations make security techniques proposed for terrestrial networks more challenging in satellite settings. Denial-of-service (DoS) and distributed DoS (DDoS) attacks have become one of the most popular security threats in both the terrestrial and satellite networks. In this article, we present a DDoS mitigation technique that can be employed at the GS end in satellite networks. In particular, we simulate Internet Control Message Protocol echo request (ping) flooding across a satellite network and propose a proactive mitigation technique by restricting the number of echo requests a network entity can generate. The simulation results demonstrate that DDoS attacks can be mitigated in satellite networks without affecting the quality of experience of legitimate users.

Bankey et al studied the PHY security of a downlink hybrid satellite-terrestrial multi-relay network in [7]. The idea of exploiting the terrestrial resources to enhance PHY of satellite transmission has been investigated in [8].…”

This letter investigates the secrecy outage performance of satellite-to-terrestrial downlink transmissions consisting of one legitimate receiver (D) and one eavesdropper (E). To reflect the practical application scenarios, it is assumed that D and E are randomly distributed in the footprint of the satellite. Furthermore, in the considered downlink scenario, D and E are equipped with multiple antennas, and maximal ratio combining (MRC) technique is adopted at both of them to seek the maximum receiving diversity gain. To reveal the impacts of the randomness of the positions of D and E, and MRC scheme on the secrecy outage performance of the considered satellite-terrestrial system, the exact and asymptotic closed-form analytical expressions for secrecy outage probability are derived by using stochastic geometry method. Finally, simulation results are given to confirm the accuracy of our proposed analytical models.

“…In [13], the outage performance of non-orthogonal multiple access (NOMA) was studied for the ISTRN with fixed DF where one satellite serves two terrestrial users via the assistance of one single-antenna relay. In [14], the secrecy performance was studied for the ISTRN with multiple cooperative relays under adaptive DF protocols in the presence of multiple eavesdroppers. Authors in [8] adopted the incremental DF protocol for the ISTRN with multiple terrestrial users and gave the outage probability analysis.…”

“…Single and several relays providing best received SNRs perform the transmission in non-cooperative and cooperative modes, respectively. Relay selection under non-cooperative mode was considered for the ISTRN in [14]. And in [15] the outage and SER performance were studied for the ISTRN with relay selection under cooperative mode.…”

Satellite communication plays an important role in future wireless network. In this article, we investigate the outage performance of the integrated satellite-terrestrial relay network (ISTRN) with relay selection based adaptive decode-and-forward (RSADF), where the relay selection is based on outdated channel state information (CSI), and the multiple-antenna relays conduct maximum-ratio receiving and transmitting for decoding and forwarding, respectively. Particularly, we first obtain a novel closed-form expression for the outage probability of the considered ISTRN with RSADF. Furthermore, to get further insights of the effect of key system parameters, e.g., the number of relays, the number of antennas, the CSI outdating level, and the channel fading characteristics, on the system performance, we conduct asymptotic analysis for three typical high average signal-to-noise-ratio (SNR) scenarios, i.e., 1) all satellite and terrestrial links are with high average SNR, 2) the satellite-to-relay link and the relay-to-user link are with high average SNR, and 3) only the relay-to-user link is with high average SNR. The derived high SNR approximations of outage probability explicitly reveal the impact of key system parameters in the form of diversity gain and coding gain. Finally, numerical simulations are presented to validate the analytical results. INDEX TERMS Satellite communications, adaptive decode and forward, relay selection, outdated CSI.
