Router Keying for BGPsec
draft-ietf-sidr-rtr-keying-08
Abstract
BGPsec-speaking routers are provisioned with private keys to sign BGP
messages; the corresponding public keys are published in the global
RPKI (Resource Public Key Infrastructure) thereby enabling
verification of BGPsec messages. This document describes two ways of
provisioning the public-private key-pairs: router-driven and
operator-driven.

1. Introduction
BGPsec-speaking routers are provisioned with private keys, which
allow them to digitally sign BGP messages. To verify the signature,
the public key, in the form of a certificate [I-D.ietf-sidr-bgpsec-
pki-profiles], is published in the RPKI (Resource Public Key
Infrastructure). This document describes two methods for
provisioning the necessary public-private key-pairs: 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 method. Routers are expected to support either
one, the other, or both methods to work in various deployment
environments. Some routers may not allow the private key to be off-
loaded while other routers may. Off-loading of private keys would
support swapping of routing engines which could then have the same
private key installed in the soon-to-be online engine that had
previously been installed in the soon-to-be removed card.
The remainder of this document describes how operators can use the
two methods to provision new and existing routers.
Note: [I-D.ietf-sidr-bgpsec-pki-profiles] specifies the format for
the PKCS #10 request and [I-D.ietf-sidr-bgpsec-algs] specifies the
algorithms used to generate the signature.
2. Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" are to
be interpreted as described in RFC 2119 [RFC2119] only when they
appear in all upper case. They may also appear in lower or mixed
case as English words, without normative meaning.
Readers are assumed to be familiar with the BGPsec protocol [I-
D.ietf-sidr-bgpsec-overview][I-D.ietf-sidr-bgpsec-protocol] and the
RPKI [RFC6480] as well as the BGPsec-specific PKI (Public Key
Infrastructure) specifications [I-D.ietf-sidr-bgpsec-pki-profiles][I-
D.ietf-sidr-bgpsec-algs].
3. Provisioning a New Router
Depending on the options supported by the new router, operators are
free to use either the router-driven or operator-driven methods.
