RPKI Signed Object for Trust Anchor Keys
draft-ietf-sidrops-signed-tal-02
Abstract
Trust Anchor Locators (TALs) [I-D.ietf-sidrops-https-tal] are used by
Relying Parties in the RPKI to locate and validate Trust Anchor
certificates used in RPKI validation. This document defines an RPKI
signed object for Trust Anchor Keys (TAK), that can be used by Trust
Anchors to signal their set of current keys and the location(s) of
the accompanying CA certiifcates to Relying Parties, 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.
