This thesis presents an in-depth exploration of designing a cybersecurity system for satellitecommunication, addressing cyberthreats as the space industry transitions from security byobscurity in mission specific designs to the use of mass-produced components. To counteract these threats, a comprehensive security system must be implemented,considering all facets of satellite communication, from key management and encryption to digitalsignatures, digital certificates, and hardware security modules (HSMs). The role of HSMs insecurely storing cryptographic keys and performing cryptographic operations is emphasized,highlighting their importance in protecting sensitive data. A partial implementation of the digital signature component demonstrates the practicalimportance of using HSMs for key storage, underscoring the feasibility of the proposed systemin real-world applications. The findings indicate that established protocols and algorithms, when combined effectively, can provide robust security solutions for satellite communication. This research contributes to the development of secure satellite communication systems byoffering a detailed security design tailored to the specific needs and challenges of the spaceenvironment. It provides a framework for future implementations, ensuring that satellite systemscan operate securely and efficiently in an increasingly interconnected and vulnerable digitallandscape.
