Traceability in supply chains is a growing security concern. While Verifiable Data Structures (VDSs) have addressed specific issues, such as equivocation over digital certificates, they lack a universal architecture for all supply chains. This document defines such an architecture for single-issuer signed statement transparency. It ensures extensibility and interoperability between different transparency services as well as compliance with various auditing procedures and regulatory requirements.
This document is a product of the Supply Chain Integrity, Transparency, and Trust Working Group of the IETF.
STANDARDS TRACK: This document specifies an Internet Standards Track
