The Federated Trust Model Explained

This section provides an accessible explanation of how the Federated PKI model connects global participants while preserving local sovereignty.

Core Concept Each participant within the Federated Trust ecosystem operates under a local Trust Framework Instance (TFI), adhering to the shared assurance, cryptographic, and governance rules defined by the TSCP Policy Management Authority (PMA).

Bridge Integration The TSCP Bridge Services provide the technical and policy alignment that allow these TFIs to interoperate seamlessly — ensuring trust is maintained across borders and domains.
