The problem
What today's M2M auth can't deliver in subsea.
Subsea M2M communication operates over acoustic links with bandwidths in the kilobits per second, latencies in seconds, and packet-loss profiles unlike any RF medium. Authentication overhead in this regime is not affordable; many operators simply skip authentication, accepting the operational risk.
How EdSSA addresses it
What EdSSA does differently here.
EdSSA Nano, calibrated for acoustic-link envelopes, provides authentication that fits inside acoustic-link bandwidth budgets and tolerates surfacing-window mediated key updates. Underwater unmanned vehicle (UUV) swarms authenticate to each other and to surface vessels without a shore-station round-trip.
Use cases
Concrete operational scenarios.
- UUV swarm authentication for pipeline inspection and naval surveillance
- Submarine-to-surface authentication tolerant of acoustic-link envelopes
- Subsea sensor network authentication for offshore-energy installations
- Authenticated acoustic communication between AUVs and host vessels
Compliance & standards
Standards and regulatory regimes.
NATO STANAG 1248 acoustic-link compatibility at architectural level. UN UNCLOS clean. EU NIS2 for offshore-energy operators.
Audit emission
Local audit log buffered until next surfacing window, then shipped to surface infrastructure. Tamper-evident on extended-isolation operations.
