The problem
What today's M2M auth can't deliver in trade finance.
Trade-finance documentary credit chains involve issuing bank, advising bank, confirming bank, presenting bank, exporter, importer, freight forwarder, and customs. Authentication today rests on SWIFT message authentication and cryptographic seals on individual documents. Neither provides end-to-end cryptographic provenance across the multi-party chain, and neither has a clean post-quantum migration path.
How EdSSA addresses it
What EdSSA does differently here.
EdSSA Nano provides multi-party document custody authentication with the same single-bootstrap, forever-after authentication property as the rest of the protocol family. Documentary chains acquire intrinsic cryptographic provenance. Disputes acquire cryptographic adjudication evidence.
Use cases
Concrete operational scenarios.
- Letter-of-credit chain authentication across issuing, advising, and confirming banks
- Bill-of-lading custody authentication along the freight chain
- Documentary-collection presentation authentication
- Export-credit-agency-backed instrument authentication
