1. Introduction
This document defines a Trust Anchor Locator (TAL) for the Resource
Public Key Infrastructure (RPKI) [RFC6480]. This format may be used
to distribute trust anchor material using a mix of out-of-band and
online means. Procedures used by Relying Parties (RPs) to verify
RPKI signed objects SHOULD support this format to facilitate
interoperability between creators of trust anchor material and RPs.
1.1. Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in [RFC2119].
2. Trust Anchor Locator
2.1. Trust Anchor Locator Format
This document does not propose a new format for trust anchor
material. A trust anchor in the RPKI is represented by a self-signed
X.509 Certification Authority (CA) certificate, a format commonly
used in PKIs and widely supported by RP software. This document
specifies a format for data used to retrieve and verify the
authenticity of a trust anchor in a very simple fashion. That data
is referred to as the TAL.
The motivation for defining the TAL is to enable selected data in the
trust anchor to change, without needing to effect redistribution of
the trust anchor per se. In the RPKI, certificates contain
extensions that represent Internet Number Resources (INRs) [RFC3779].
The set of INRs associated with an entity likely will change over
