Router Keying for BGPsec
draft-ietf-sidr-rtr-keying-04
Abstract
BGPsec-speaking routers must be provisioned with private keys and the
corresponding public key must be published in the global RPKI
(Resource Public Key Infrastructure). This document describes two
ways of provisioning public/private keys, router-driven and operator-
driven.

1. Introduction
BGPsec-speaking routers must be provisioned with private keys and the
corresponding public key must be published in the global RPKI
(Resource Public Key Infrastructure). The public key is published in
the RPKI in the form of a certificate [I-D.ietf-sidr-bgpsec-pki-
profiles]. This document describes two methods for generating the
necessary public/private key-pair: router-driven and operator-driven.
The difference between the two methods is where the keys are
generated: on the router in the router-driven method and elsewhere in
the operator-driven model. Different equipment necessitates the two
methods. Some equipment doesn't allow the private key to be off-
loaded while other equipment does. Off-loading private keys supports
hot-swappable routers that need to have the same private key needs
installed in the soon-to-be online router that was installed in the
soon-to-be offline router.
The remainder of this document describes how operators can use the
two methods to provision new and existing routers.
Note that in both models, the key pair is for algorithms defined in
[I-D.ietf-sidr-bgpsec-algs]. The first version specifies ECDSA on
the P-256 curve.
2. Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
"OPTIONAL" in this document are to be interpreted as described in RFC
2119 [RFC2119].
It is assumed that the reader understands BGPsec [I-D.ietf-sidr-
bgpsec-overview] [I-D.ietf-sidr-bgpsec-protocol], the RPKI [RFC6480],
and [I-D.ietf-sidr-bgpsec-pki-profiles].
3. Provisioning a New Router
When commissioning a new router, operators may use either the router-
driven or operator-drive methods. Regardless of the method chosen,
the operator first needs to establish a secure communication channel
with the router. Operators use the router-specific procedures to
enable them to connect to the router via an SSH session.
