When you operate satellites, spacecraft, or platforms with periodic communication windows.
What it is
EdSSA Orbit in one paragraph.
EdSSA Orbit couples cryptographic state advancement to physical events that satellites and spacecraft observe naturally — perigee passages, eclipse exits, ground-station acquisitions. Hibernation handshakes survive multi-orbit communication gaps. Post-pass synchronisation does not need a re-bootstrap.
When you need it
Three signals you should look at this tier.
When ground-station unavailability must not interrupt inter-satellite authentication.
When your authentication must survive multi-day or multi-orbit comms gaps.
How it composes
Where this tier sits in the protocol family.
Protocol family
Nano is the foundation. Fleet, Swarm, Relay, Edge, and Orbit compose on top of it. Most deployments use two or three tiers together.
Orbit is the satellite-native expression of Nano. It composes with Swarm for constellation-scale operations and with Relay for ground-station-tiered topologies.
Industries served
Where this tier earns its keep.
SATELLITES
Archive-grade provenance above the existing space-security stack.
SPACE EXPLORATION
Archive-grade provenance for long-duration, long-archive missions.
DEFENCE
Sovereign-grade post-quantum auth for mission-critical operations.
CRITICAL INFRASTRUCTURE
Air-gapped, sovereign, post-quantum, audit-grade.
Patent posture
Patent pending · Filed 1 May 2026EdSSA Orbit is part of the patent application “Decentralised Stateless Structural Authentication” — filed at the Finnish Patent and Registration Office (PRH) on 1 May 2026, a European-jurisdiction filing with PCT international extension planned within the priority year. Fifty-four claims and eleven figures.
