SpaceComputer to Test Open-Source Satellite Security in October Demo

SpaceComputer will test its secure satellite compute system in October. The demo mission, aboard a Spacemanic satellite, will showcase Space Fabric, an open-source architecture designed to enhance satellite security. The system aims to address growing concerns about hacking risks in space operations. Space Fabric combines hardware and software to sit above a satellite’s main computer. It does not interfere with the existing on-board systems. Instead, it provides verifiable proof that processes run in orbit remain untouched and genuinely occur in space.

The architecture introduces two key security features for the demo. It creates a physical barrier between different payloads to prevent interference. It also generates cryptographic keys directly on the satellite, ensuring sensitive data never passes through ground systems or other payloads.

SpaceComputer’s CTO emphasised the need for such solutions, especially for rideshare satellites. These often carry multiple payloads, increasing the risk of unauthorised access. Officials note that hacking threats extend beyond communications, affecting supply chains and on-board systems themselves. The October mission will validate Space Fabric’s ability to secure shared satellite environments. By offering cryptographic proofs and physical isolation, the system aims to prevent tampering or eavesdropping. This could mark a shift from closed, custom security systems to a more open and adaptable approach.
