The problem
What today's M2M auth can't deliver in v2x.
V2X authentication via SCMS-style PKI introduces latency budgets that high-speed cooperative manoeuvres cannot tolerate, depends on RSU connectivity that is not always present, and provides no clean post-quantum migration for vehicles with twelve-to-fifteen-year lifecycles.
How EdSSA addresses it
What EdSSA does differently here.
EdSSA Nano provides sub-microsecond mutual authentication between any two vehicles or any vehicle-and-RSU pair. After a single bootstrap, no further authority round-trip is needed. Authentication holds through urban-canyon RF degradation, mountain-pass connectivity gaps, and tunnel transits.
Use cases
Concrete operational scenarios.
- Cooperative-driving manoeuvre authentication (platooning, lane-change negotiation)
- Authenticated emergency-vehicle priority signalling across V2I infrastructure
- Authenticated over-the-air firmware updates for in-vehicle ECUs
- Cross-OEM V2V authentication without a shared SCMS authority
Compliance & standards
Standards and regulatory regimes.
ETSI ITS-G5 and C-V2X compatibility at upper layer. ISO/SAE 21434 cybersecurity engineering. UN-R 155 / UN-R 156 type-approval alignment.
Audit emission
Per-interaction audit emission at sub-microsecond cost per verification. Compatible with UNECE WP.29 cybersecurity management system requirements and EU CCAM audit specifications.
