Digital trust
Trust is an operating service, not a certificate file.
Architecture and engineering for PKI, certificate lifecycle, trust distribution and electronic signature services.
Advice on trust-service architecture does not imply licensed, qualified or accredited service-provider status.
Architecture and assurance
Digital trust depends on accountable authorities, governed trust sources and reliable operations. We help organisations define those relationships and engineer the services that make them usable in identity systems.
- PKI and trust-service architectureRoot and subordinate authority models, certificate policy, trust domains, operational controls and separation of issuer and verifier trust.
- Certificate lifecycle managementIssuance, key protection, renewal, suspension, revocation, status publication and emergency response.
- HSM and key-management integrationSecurity boundaries, ceremony design, role separation, key inventory and integration with cryptographic services.
- Trust lists and distributionGoverned trust sources, authenticated updates, freshness, removal, offline handling and auditability.
- Electronic signatures and timestampsArchitecture for signature creation and validation, trusted time, evidence preservation and service integration.
- OCSP, CRLs and status servicesAvailability, caching, freshness, privacy, high-volume validation and failure policy for certificate-status systems.
Trust boundaries
Different trust questions need different authorities.
Document issuer trust, relying-party authorisation, wallet attestation and platform integrity are not interchangeable. A trust architecture must define the source, scope, distribution and revocation policy for each decision.
