TSCP–Federal Bridge (Federal Line)

What it is

The TSCP Federal Bridge is TSCP’s federal-aligned trust framework Bridge that enables policy-driven interoperability among TSCP members and participating federal stakeholders. It provides a governed model for assurance alignment, certificate trust interoperability, and auditable operations—while allowing each organization to preserve local control of its PKI and security posture.

What it enables

Through the TSCP Federal Bridge, participants can support:

  • Policy-aligned trust interoperability across approved federal and non-federal participants

  • Certificate path discovery and validation within the Bridge trust ecosystem

  • Consistent identity assurance outcomes via shared governance, onboarding, and lifecycle requirements

  • Audit-ready trust operations (issuance/renewal, revocation, incident response expectations)

What It Provides

Cross-certification interoperability with the U.S. Federal PKI trust ecosystem (FBCA-aligned)

Policy and assurance mapping aligned to federal certificate policy expectations

Trusted identity recognition between TSCP members and federal relying parties

Cryptographic interoperability supporting authentication, encryption, and digital signatures

Lifecycle transparency for issuance, renewal, revocation, and validation operations

Audit-ready operations supporting governance traceability and compliance evidence

Zero-trust enablement for regulated, mission-critical environments

How It Works

  • Step 1: Participating CAs align to required federal assurance and cryptographic requirements.
  • Step 2: TSCP performs certificate policy mapping and documents equivalence to federal expectations.
  • Step 3: Cross-certificates are established (as applicable) to enable trusted path validation.
  • Step 4: Relying parties validate certificate paths using published trust artifacts and status services.
  • Step 5: Ongoing operations maintain revocation, lifecycle controls, and periodic compliance evidence.

Governance & Assurance

  • Overseen by the TSCP Federal PMA under the Federated PMA governance model.
  • Ensures policy equivalence, assurance mapping, and cross-certification integrity.
  • Supports auditability through controlled lifecycle processes and evidence-ready operations.

Trust Lists / Interoperability Lab

Uses TSCP-published trust artifacts (Trust List / interoperability trust data) to support relying-party validation and operational transparency.

Interoperability testing validates certificate path building and revocation checking prior to broad deployment.

 

Where this fits in TSCP Federated Trust

TSCP operates three independent trust lines—Federal (FBCA), Aviation (IATF), and AI Trust (AI Bridge)—coordinated under a common federated governance model. Each line maintains separate policy authority and assurance scope, while sharing common trust principles and consistent interoperability mechanisms.

This framework supports secure collaboration where Federal assurance, transparency, and reliability are mandatory.
