A VHL Sharer or VHL Receiver, as a participant in the trust network, SHALL be capable of retrieving public key infrastructure (PKI) material from a designated Trust Anchor.

The retrieved material MAY include:

• Public key certificates and associated trust lists
• Certificate revocation data (e.g., CRLs, OCSP responses)
• Metadata used to:
  • Validate digital signatures on VHLs and related resources
  • Establish secure connections
  • Decrypt content protected via asymmetric encryption

Participants SHOULD cache the received trust list to reduce network and server load.

Preconditions:

• The requesting participant knows in advance the endpoint from which to retrieve PKI material, as published or distributed by the Trust Anchor.
