Router Keying for BGPsec
draft-ietf-sidr-rtr-keying-16
Abstract
BGPsec-speaking routers are provisioned with private keys in order to
sign BGPsec announcements. The corresponding public keys are
published in the global Resource Public Key Infrastructure, enabling
verification of BGPsec messages. This document describes two methods
of generating the public-private key-pairs: router-driven and
operator-driven.
Requirements Language
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 BCP
14 [RFC2119] [RFC8174] when, and only when, they appear in all
capitals, as shown here.
