The problem
What today's M2M auth can't deliver in space exploration.
Lunar, cislunar, and deep-space missions face authentication challenges fundamentally different from LEO. Light-time delay makes round-trip authentication impossible; multi-day blackouts and irrecoverable loss-of-contact are routine. Existing space cryptography assumes ground-station reach-back at command-execution time, which deep-space simply cannot guarantee.
How EdSSA addresses it
What EdSSA does differently here.
EdSSA Orbit was designed for this regime. State advancement is keyed to physical events the spacecraft observes locally — perigee passage, eclipse exit, communication-window acquisition. Hibernation handshakes survive multi-orbit and multi-day comms gaps without re-bootstrap. Light-time-delay does not block authentication.
Use cases
Concrete operational scenarios.
- Lunar lander and rover authentication during ground-blackout windows
- Cislunar relay station authentication for cross-mission data transit
- Deep-space probe authentication with light-time delays beyond round-trip viability
- Authenticated commanding of long-duration unmanned exploration platforms
