TRUST INFRASTRUCTURESERVICE REFERENCE

Cryptographic trust stays inside explicit trust boundaries.

Private keys do not belong in DPP/business repositories. Trust services remain external dependencies unless explicitly part of the deployment.

TRUST DEPENDENCIES

Use each trust service for a precise purpose.

Provider, licence/certificate scope and availability must be deployment-specific.

EXTERNAL / DEPLOYMENT

CA / Device CA

Certificate issuance/status domain. Certificate status is not runtime trust.

EXTERNAL / DEPLOYMENT

TSA / Trusted Time

Trusted-time evidence for material events where selected.

REGULATED DEPENDENCY

eSeal / Digital Signature

Use regulated trust services where legally/contractually required; do not imply ThingID itself holds the licence.

CRYPTO BOUNDARY

HSM / KMS

Key protection and cryptographic boundary; no private key in DPP repository.

PKI STATUS

OCSP / CRL

Certificate status from PKI source.

OPTIONAL / PROFILE

Archive / LTV

Long-term evidence retention/renewal according to deployment and policy.
