Secure Dataspace Approach for Interorbital Satellite Links

Abstract

Satellite systems have a critical role in various domains such as communication, navigation, earth observation, and scientific research. Security of the data transmitted by satellite systems is of utmost importance to ensure the confidentiality, integrity, and availability of sensitive information. Satellite operators withhold orbital location data, despite the imperative to share information to avert collisions. In order to cope with these requirements, this proposed approach combines the concept of the GAIA-X data ecosystem with advanced privacy preserving techniques and decentralized computations. In order to do so, this paper uses technologies, such as secure multiparty computation (MPC) and homomorphic encryption (HE), to ensure data sovereignty for international collaboration in space missions. By sticking to the GAIA-X core values, this approach incorporates principles such as openness and transparency, federation, security-by-design and interoperability for an interorbital satellite link.
