Zero Trust for LEO Satellite Command Systems
Abstract: This paper proposes Mission-Zero, a Zero Trust security architecture designed for Low Earth Orbit satellite command systems. Traditional satellite security models rely heavily on trusted ground infrastructure and perimeter-based defenses, which are increasingly insufficient against modern cyber threats such as RF spoofing, command replay attacks, and ground system compromise. The proposed framework introduces continuous verification across the entire command chain, including operator authentication, command validation, ground station protection, secure RF communication, and onboard satellite verification. By applying Zero Trust principles to satellite command and control infrastructure, the architecture improves resilience against unauthorized command injection and infrastructure compromise while maintaining lightweight operational overhead suitable for LEO missions.
