Engineering cryptographic frame authentication and encryption pipelines for satellite telecommand and telemetry links.
Historical satellite operations relied on obscurity and specialized ground antennas for security. Today, software-defined ground stations can easily transmit forged telecommand (TC) frames to unauthenticated satellites, potentially altering orbital vectors, disabling solar arrays, or initiating de-orbit burns. SpaceHSM enforces the CCSDS SDLS standard, cryptographically authenticating every single telecommand frame.
Satellite uplink data rates are often constrained to kilobits per second. SpaceHSM supports optimized cryptographic encapsulation that adds minimal byte overhead to CCSDS transfer frames while delivering 256-bit authenticated encryption.
