“…The Ka-band modem employs channel-efficient ACM with LDPC codes for error correction. Multi-frequency time-division multiple access (MF-TDMA) and multiplexing schemes are employed in the system [57]. The building blocks of the GeReLEO concept are LEO satellites equipped with a GeReLEO modem, a GeReLEO gateway, a GeReLEO network control center, and a data relay payload on-board a GEO satellite [57].…”

This survey 1 fills in an important gap in the literature on CubeSat communication systems’ designs and architectures. The paper 2 comprehensively reviews the design details in-depth and 3 critically evaluates the performance and reliability of the reviewed systems by analyzing the demonstration and testing results and illustrating implicit assumptions in the reviewed works. Furthermore, the paper 4 proposes an original CubeSat communication system categorization based on the design approach and 5 analyzes the features and limitations of each category. Consequently, this leads to identifying the limitations of current CubeSat communication systems and the promising future developments that can boost CubeSat communications capabilities.

“…These satellites are at shorter distances from Earth, so they have higher signal strength and lower latency [6,7]. However, unlike the Geosynchronous-Equatorial-Orbit (GEO) satellite, which alone covers the entire surface of the earth, several LEO satellites are required for this purpose [8].…”

Satellite networks are recognized as the most essential communication infrastructures in the world today, which complement land networks and provide valuable services for their users. Extensive coverage and service stability of these networks have increased their popularity. Since eavesdropping and active intrusion in satellite communications are much easier than in terrestrial networks, securing satellite communications is vital. So far, several protocols have been proposed for authentication and key exchange of satellite communications, but none of them fully meet the security requirements. In this paper, we examine one of these protocols and identify its security vulnerabilities. Moreover, we propose a robust and secure authentication and session key agreement protocol using the elliptic curve cryptography (ECC). We show that the proposed protocol meets common security requirements and is resistant to known security attacks. Moreover, we prove that the proposed scheme satisfies the security features using the Automated Validation of Internet Security Protocols and Applications (AVISPA) formal verification tool and On-the fly Model-Checker (OFMC) and ATtack SEarcher (ATSE) model checkers. We have also proved the security of the session key exchange of our protocol using the Real or Random (RoR) model. Finally, the comparison of our scheme with similar methods shows its superiority.
