SpaceComputer Unveils Space Fabric to Secure Satellite Shared Systems

SpaceComputer has developed a new secure compute architecture for satellites called Space Fabric. The system aims to improve security for shared satellite bus scenarios, where multiple payloads operate on the same spacecraft. Officials at the company stress the growing need for protection between subsystems in such setups. Space Fabric combines hardware and software that sits on top of a satellite’s compute module. It provides verifiable proof of security without affecting the on-board computer’s performance. The architecture is open-source, addressing the limitations of current bespoke and closed-source systems.

The system generates cryptographic keys directly on board the satellite. This ensures sensitive data never touches terrestrial systems or other payloads. It also produces cryptographic proofs to confirm that processes executed in orbit were indeed run there.

A demo mission is planned for October on a Spacemanic satellite. The test will validate two key features: a physical barrier between payloads and cryptographic proofs for process verification. The barrier prevents unauthorised access or tampering with orbital compute operations. The demo mission will showcase Space Fabric’s ability to secure shared satellite environments. The system’s open-source design and on-board key generation address critical security gaps. SpaceComputer’s CTO underlines the importance of such solutions for modern satellite operations.
