A Unified Federation of Independent Trust Hierarchies.

TSCP LLC operates three discrete yet interoperable PKI hierarchies—Federal, Aviation, and AI—each governed by a consistent Policy Management Authority (PMA) framework to ensure global interoperability. This page visually represents the TSCP Bridge ecosystem, providing context for how cross-certification, trust policy alignment, and assurance mapping occur across different domains.

Cross-Domain PKI Connections

Visualizing Interoperable PKI Lines

The TSCP Bridge acts as the central hub, unifying three distinct PKI hierarchies. This structure allows independent sectors to maintain their specific security requirements while establishing seamless trust relationships with one another.

Federal Line (TSCP–FBCA Bridge)

The Federal Line provides interoperability with the U.S. Federal Bridge Certification Authority (FBCA) for agency and defense systems. This line includes the TSCP Bridge Root, Cross-Signing CA, Member Federal / Agency Issuing CAs, and supports mTLS and Device Certificates.

Aviation Line (TSCP–IATF Bridge)

The Aviation Line aligns with ICAO Docs 10169 and 10204, supporting aviation service providers, ANSPs, airports, and regulators through Trust Framework Instances (TFIs). It includes the TSCP Aviation Root, IATF Bridge CA, National / Organizational TFIs, and Certificate Policies for CNS/ATM and Service TLS.

AI Line (TSCP–AI Bridge)

The AI Line provides assurance for AI models, APIs, and supply-chain components under NIST AI Framework, ISO 42001 and EU AI Act principles. This structure features the TSCP AI Root, AI Bridge CA, Issuing CAs for AI Model / API Identity, and supports AI Provenance & Validation Certificates.
