SpaceComputer Unveils Open-Source Security for Satellite Networks

SpaceComputer has developed a new open-source architecture called Space Fabric to improve satellite security. The system aims to address growing risks as satellites increasingly share compute resources. It offers a more secure alternative to current bespoke, closed-source solutions. Satellites now rely more on partners for compute components, creating vulnerabilities. Rideshare missions with multiple payloads on a single bus increase the risk of attacks between payloads. SpaceComputer’s CTO, Filip Rezabek, stressed the need for stronger security between subsystems.

Space Fabric tackles these risks with two key features. It creates a physical barrier to prevent tapping or tampering with orbital operations. It also generates cryptographic proofs to verify that processes ran securely in orbit. The system produces cryptographic keys on board, ensuring sensitive data never touches terrestrial systems or other payloads.

According to CEO Daniel Bar, the technology provides verifiable security without affecting the satellite’s main computer. A demo mission is planned for October, with Space Fabric set to launch on a Spacemanic satellite. The upcoming mission will test Space Fabric’s ability to secure shared satellite systems. Its physical barriers and cryptographic proofs could set a new standard for orbital compute security. The demo aims to prove the system’s effectiveness in real-world conditions.
