Enterprise DRM: Terminal Link Integration & Backend Validation

[arkavo-com]

Overview

Integrate Terminal Link authentication with backend validation for enterprise-grade DRM.

Client-Side Tasks

• NTDF chain construction (PE→NPE) - PR NTDF Token Attestation #161
• DPoP proof generation - PR NTDF Token Attestation #161
• App Attest integration - PR NTDF Token Attestation #161
• Terminal Link request/response handling
• Session management integration

Backend Integration

• Send Terminal Link in X-Auth-Token header
• Handle Terminal Link refresh on expiry
• Integrate with session heartbeat
• Error handling for attestation failures

Testing

• Test with real App Attest on device
• Test session expiry and renewal
• Test DPoP binding validation
• Test jailbreak detection honeypot response

Security Level

Target: Maximum (Enterprise-Grade)

• Hardware-attested devices only
• Token binding via DPoP
• Graceful degradation for honeypot scenarios

Acceptance Criteria

• Terminal Link sent in all authenticated requests
• App Attest assertions generated per session
• DPoP proofs bound to requests
• All tests pass on real devices
