RPKI Signed Object for Trust Anchor Keys
draft-ietf-sidrops-signed-tal-05
Abstract
A Trust Anchor Locator (TAL) [I-D.ietf-sidrops-https-tal] is used by
Relying Parties (RP) in the RPKI to locate and validate a Trust
Anchor (TA) CA certificate used in RPKI validation. This document
defines an RPKI signed object for a set of Trust Anchor Keys (TAK),
that can be used by TA creators and publishers to signal their set of
current keys and the location(s) of the accompanying CA certificates
to RPs, as well as changes to this set in the form of revoked keys
and new keys, in order to support both planned and unplanned key
rolls without impacting RPKI validation.
