The problem
What today's M2M auth can't deliver in specialised couriers.
Specialised courier operations — organ transplant, forensic evidence, diplomatic mail, controlled substances — depend critically on demonstrable chain of custody. Today most rely on signed paper manifests, scanned barcodes, and operator goodwill. None provides cryptographic non-repudiation of handler-to-handler transfer, and none survives the post-quantum horizon.
How EdSSA addresses it
What EdSSA does differently here.
EdSSA Nano provides cryptographic custody handoff between any two parties who have shared a single bootstrap. The custody record is non-repudiable, post-quantum, and operates across multi-day transit, customs holds, and intermittent connectivity. Court-admissible custody records become a property of the protocol, not a procedural addendum.
Use cases
Concrete operational scenarios.
- Organ-transplant courier custody with sub-second handoff verification
- Forensic evidence transit with court-admissible cryptographic chain
- Diplomatic-mail courier authentication across embassy and consulate networks
- Controlled-substance shipment authentication for regulated pharmaceutical and medical use
Compliance & standards
Standards and regulatory regimes.
UN Vienna Convention on Diplomatic Relations alignment. National forensic-evidence chain-of-custody standards. DEA Schedule II handling. UNOS organ-transport requirements.
Audit emission
Cryptographically chain-of-custody-grade audit logging. Per-handler event records, optional tamper-evident Merkle anchoring for evidence admissibility and regulatory inspection.
