“…Despite its innovative approach, the framework relies on digital signatures and encryption, raising concerns about computational feasibility in the constrained environment, alongside its dependence on a single trust anchor. Challa et al [30] proposed CubeSec and GndSec, lightweight security solutions for CS communications, acknowledging the need for efficient security measures in resource-constrained environments. However, the security of their approach relies heavily on pre-shared keys as they utilize symmetric encryption.…”

The recent rise of CubeSat has revolutionized global space explorations, as it offers cost-effective solutions for loworbit space applications (including climate monitoring, weather measurements, communications, and earth observation). A salient feature of CubeSat is that applications currently on-boarded can either be updated or entirely replaced by new applications via software updates, which allows reusing in-orbit hardware, reduces space debris, and saves cost as well as time. Securing software updates employing traditional methods (e.g., encryption) remains impractical mainly due to the low-resource capabilities of CubeSat. Therefore, the security of software updates for CubeSats remains a critical issue.In this paper, we propose CubeSat Update Mechanism (CSUM), a lightweight scheme to provide integrity, authentication, and data freshness guarantees for software update broadcasts to CubeSats using a hash chain. We empirically evaluate our proof of concept implementation to demonstrate the feasibility and effectiveness of our approach. CSUM can validate 50,000 consecutive updates successfully in less than a second. We also perform a comparative analysis of different cryptographic primitives. Our empirical evaluations show that the hash-based approach is at least 61× faster than the conventional mechanisms, even in resource-constrained environments. Finally, we discuss the limitations, challenges, and potential future research directions for CubeSat software update procedures.

“…In the CGR and extended-CGR methods, CubeSats transmit to the ground station only when they have enough energy for data forwarding. Nevertheless, Challa et al proposed a torrent-based approach for CubeSats to improve the downlink and uplink times for large file transmissions [129]. In CubeSat-torrent, large files are split into small chunks, resulting in low latency.…”

Given the increasing number of space-related applications, research in the emerging space industry is becoming more and more attractive. One compelling area of current space research is the design of miniaturized satellites, known as Cube-Sats, which are enticing because of their numerous applications and low design-and-deployment cost. The new paradigm of connected space through CubeSats makes possible a wide range of applications, such as Earth remote sensing, space exploration, and rural connectivity. CubeSats further provide a complementary connectivity solution to the pervasive Internet of Things (IoT) networks, leading to a globally connected cyber-physical system. This paper presents a holistic overview of various aspects of CubeSat missions and provides a thorough review of the topic from both academic and industrial perspectives. We further present recent advances in the area of CubeSat communications, with an emphasis on constellation-and-coverage issues, channel modeling, modulation and coding, and networking. Finally, we identify several future research directions for CubeSat communications, including Internet of space things, low-power long-range networks, and machine learning for CubeSat resource allocation.

The research in the emerging space industry is becoming more and more attractive, given the increasing number of space-related applications. One primary entity of current space research is the design of miniaturized satellites, known as CubeSats, due to their numerous applications and low design and deployment cost.

We further present the recent advances in the area of CubeSats communications with an emphasis on constellation and coverage issues, channel modeling, modulation and coding, and networking. The paper finally identifies several future research directions on CubeSats communications, namely Internet of space things, low power long range networks, machine learning for resource allocation in CubeSats, etc.
