“…The results show that the minimum number of BS required by proposed and existing methods are atleast 60 and 62 BS antennas. Also, the EE is (7-24) Mbits for proposed and less than (6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18) Mbits for existing methods under different SEs.…”

“…11,12 Beamforming is one of the techniques to improve EE and SE. 13,14 Beamforming reduces energy consumption by distributing it across several transmitters and increasing the receiver signal strength. Cheap components are inclined to have equipment disabilities, for example, phase noise, nonlinear power amplifiers, in-phase/quadrature-phase imbalance (IQI), non-linear low noise amplifiers and analog-todigital conversion (ADC) impairments which will influence the performance of the framework.…”

Summary The massive multiple input multiple output (mMIMO) provides reliable base station (BS) for the mobile users (MUs) with CSI (channel state information) and jointly offers spectral efficiency (SE) and energy efficiency (EE). Conversely, because of the existence of multiple transceivers at both the transmitter and receiver side, the channel estimation (CE) issue is increasingly complex and expensive in terms of hardware and energy utilization. Hence, we have proposed an effective Hybrid Grey Wolf Optimization with Cuckoo Search (GWO‐CS) based optimal channel estimation for developing energy efficient mMIMO. The proposed GWO‐CS selects the optimal channel by jointly optimizing the spectral efficiency and reduces the SINR (signal to interference plus noise ratio). Experimental analysis of the performance of the proposed approach is carried out using existing approaches. The results obtained show that, the EE of the proposed GWO‐CS based CE provides 15–37 Mbits for varying quantization bits, 22.5–25 Mbits for different user equipment (UE) ranges and 7–24 Mbits for various SE. However, the existing approaches fail to provide such EE and this proves the efficiency of proposed approach.

“…Most of the works focused on the improved advanced encryption standard (AES) algorithms with the same encryption and decryption keys [4][5][6][7][8][9]. While these improved AES-based cryptography schemes have been successful in preventing communications from being intercepted, recent advances in the computational power of satellite internet devices have caused some security threats [10]. Unlike the improved AES, quantum encryption is a new approach that uses quantum mechanics for key generation, ciphertext communication, and antieavesdropping [11].…”

Satellite internet serves as an indispensable component of the upcoming sixth-generation networks for providing global broadband internet access service. Due to the open nature of satellite-ground communication, security issue in satellite internet has always been an important concern for both industry and academia. Although many researchers focus on secure communications in satellite internet, the literature is surprisingly sparse, with no comprehensive overview of the state-of-the-art security techniques. This paper provides an in-depth survey of secure communications for various satellite internet scenarios. Based on different security mechanisms, we first categorize the existing works of secure communications in satellite internet into two categories: cryptography-based and physical layer security-based. The former includes classical encryption-based and quantum encryption-based secure communication, and the latter is further divided into precoding-based, cooperative jamming-based, relay selection-based, and physical-layer authentication-based secure communication depending on the applied techniques. Finally, we provide some future research directions.

“…Fortunately, transmission security of satellite communication can also be protected by physical layer security (PLS) technologies, which exploit different properties of wireless propagation channels [1]. The concept of physical layer security was pioneered by Wyner for the degraded wiretap channel model in [2], and later, it has been regarded as a complement of cryptography to achieve perfect secrecy from the informationtheoretic perspective [3]. Therefore, serving as a critical issue, PLS for satellite communication systems has already attracted much attention.…”

Satellite communication systems serve as an indispensable component of heterogeneous wireless networks in the next generation era for providing various critical civil and military applications. However, due to the broadcast nature and full accessibility of the wireless medium, such systems exist serious security threats. As an effort to address this issue, this paper, for the first time, investigates secure communication in a dual-hop communication system consisting of a satellite working as an amplified-and-forward relay. We first provide the theoretical modeling to analyze the fundamental system metrics in terms of secrecy outage probability and connection outage probability. By using the modeling, we then study the security-reliability tradeoffs and propose to transmit power schemes depending on the search algorithm. We further analyze asymptotic expressions of outage performance, which was further utilized to simplify the transmit power schemes. Simulation results show the validation of the proposed secure transmission model and design schemes of transmit power. Results also illustrate that transmit power schemes based on asymptotic analysis effectively achieve the optimal performance for the relay satellite communication system.
