Certificate Profile and Certificate Management for
SEcure Neighbor Discovery (SEND)
Abstract
SEcure Neighbor Discovery (SEND) utilizes X.509v3 certificates for
performing router authorization. This document specifies a
certificate profile for SEND based on resource certificates along
with extended key usage values required for SEND.

1. Introduction
SEcure Neighbor Discovery (SEND) [RFC3971] utilizes X.509v3
certificates that include the [RFC3779] extension for IPv6 addresses
to certify a router's authorization to advertise the IPv6 prefix for
the Neighbor Discovery (ND) protocol. The SEND specification defines
a basic certificate profile for SEND. The certificate profile
defined in this document supersedes the profile for Router
Authorization Certificates specified in [RFC3971]. That is,
certificates used in SEND (by routers, proxies, or address owners)
MUST conform to this certificate profile and MAY conform to the
original profile in [RFC3971].
The Resource Public Key Infrastructure (RPKI) is the global PKI that
attests to the allocation of IP address space. The RPKI represents
the centralized model discussed in Section 6.2 of [RFC3971].
Consequently, SEND will use the RPKI Certificate Profile and
certificate validation detailed in [RFC6487]. Consequently, the
certificate validation method described in [RFC3971] is updated with
the certificate validation method in [RFC6487].
Since the [RFC3779] IPv6 address extension does not mention what
functions the node can perform for the certified IPv6 space, it
becomes impossible to know the reason for which the certificate was
