Customer-Controlled Encryption Over Satellite

Enhancing Confidentiality, Control, and Quantum Readiness for Starlink-connected Environments or for organizations using Starlink connectivity

Low-Earth-Orbit (LEO) satellite constellations such as Starlink are redefining global connectivity by offering high-throughput, low-latency communications across the most remote environments. Yet as data traverses networks that span multiple jurisdictions and operators, encryption trust boundaries become blurred. 

Who ultimately controls the cryptographic keys and algorithms— the provider such as SpaceX or the customer—and determines whether sensitive data remains confidential, compliant, and future-proof against quantum threats. 

This paper examines provider-managed LEO connectivity security models, using Starlink as a reference example, and outlines how customer-controlled encryption can extend confidentiality and compliance for mission-critical users.
