The RPKI Repository Delta Protocol (RRDP)
Abstract
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.
