In the Resource Public Key Infrastructure (RPKI), Certificate Authorities publish certificates [RFC6487], RPKI signed objects [RFC6488], manifests [RFC6486], and CRLs to repositories. CAs may have an embedded mechanism to publish to these repositories, or they may use a separate Repository Server and publication protocol. RPKI repositories are currently accessible using the rsync protocol [RSYNC], allowing Relying Parties to synchronize a local copy of the RPKI repository used for validation with the remote repositories [RFC6481].

                The RPKI Repository Delta Protocol (RRDP)


   In the Resource Public Key Infrastructure (RPKI), Certificate    Authorities (CAs) publish certificates, including end-entity    certificates, Certificate Revocation Lists (CRLs), and RPKI signed    objects to repositories.  Relying Parties retrieve the published    information from those repositories.  This document specifies a new    RPKI Repository Delta Protocol (RRDP) for this purpose.  RRDP was    specifically designed for scaling.  It relies on an Update    Notification File which lists the current Snapshot and Delta Files    that can be retrieved using HTTPS (HTTP over Transport Layer Security    (TLS)), and it enables the use of Content Distribution Networks    (CDNs) or other caching infrastructures for the retrieval of these    files.
