A Profile for BGPsec Router Certificates,
Certificate Revocation Lists, and Certification Requests
draft-ietf-sidr-bgpsec-pki-profiles-18
Abstract
This document defines a standard profile for X.509 certificates used
to enable validation of Autonomous System (AS) paths in the Border
Gateway Protocol (BGP), as part of an extension to that protocol
known as BGPsec. BGP is the standard for inter-domain routing in the
Internet; it is the "glue" that holds the Internet together. BGPsec
is being developed as one component of a solution that addresses the
requirement to provide security for BGP. The goal of BGPsec is to
provide full AS path validation based on the use of strong
cryptographic primitives. The end-entity (EE) certificates specified
by this profile are issued (to routers within an Autonomous System).
Each of these certificates is issued under a Resource Public Key
Infrastructure (RPKI) Certification Authority (CA) certificate.
These CA certificates and EE certificates both contain the AS
Identifier Delegation extension. An EE certificate of this type
asserts that the router(s) holding the corresponding private key are
authorized to emit secure route advertisements on behalf of the
AS(es) specified in the certificate. This document also profiles the
format of certification requests, and specifies Relying Party (RP)
certificate path validation procedures for these EE certificates.
This document extends the RPKI; therefore, this documents updates the
RPKI Resource Certificates Profile (RFC 6487).

Internet-Draft BGPsec Router PKI Profiles July 21, 2016
1. Introduction
This document defines a profile for X.509 end-entity (EE)
certificates [RFC5280] for use in the context of certification of
Autonomous System (AS) paths in the Border Gateway Protocol Security
protocol (BGPsec). Such certificates are termed "BGPsec Router
Certificates". The holder of the private key associated with a
BGPsec Router Certificate is authorized to send secure route
advertisements (BGPsec UPDATEs) on behalf of the AS(es) named in the
certificate. A router holding the private key is authorized to send
route advertisements (to its peers) that contain one or more of the
specified AS number as the last item in the AS PATH attribute. A key
property provided by BGPsec is that every AS along the AS PATH can
verify that the other ASes along the path have authorized the
advertisement of the given route (to the next AS along the AS PATH).
This document is a profile of [RFC6487], which is a profile of
[RFC5280]; thus this document updates [RFC6487]. It establishes
requirements imposed on a Resource Certificate that is used as a
BGPsec Router Certificate, i.e., it defines constraints for
certificate fields and extensions for the certificate to be valid in
this context. This document also profiles the certification requests
used to acquire BGPsec Router Certificates. Finally, this document
specifies the Relying Party (RP) certificate path validation
procedures for these certificates.
1.1. Terminology
It is assumed that the reader is familiar with the terms and concepts
described in "A Profile for X.509 PKIX Resource Certificates"
[RFC6487], "BGPsec Protocol Specification" [ID.sidr-bgpsec-protocol],
"A Border Gateway Protocol 4 (BGP-4)" [RFC4271], "BGP Security
Vulnerabilities Analysis" [RFC4272], "Considerations in Validating
the Path in BGP" [RFC5123], and "Capability Advertisement with BGP-4"
[RFC5492].
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
[RFC2119].
2. Describing Resources in Certificates
Figure 1 depicts some of the entities in the RPKI and some of the
products generated by RPKI entities. IANA issues a Certification
Authority (CA) certificate to each Regional Internet Registry (RIR).
The RIR, in turn, issues a CA certificate to an Internet Service
Providers (ISP). The ISP in turn issues EE Certificates to itself to
Reynolds, et al. Expires January 22, 2017 [Page 3]
Internet-Draft BGPsec Router PKI Profiles July 21, 2016
enable verification of signatures on RPKI signed objects. The CA also
generate. The CA also generates Certificate Revocation Lists (CRLs).
These CA and EE certificates are referred to as "Resource
Certificates", and are profiled in [RFC6487]. The [RFC6480]
envisioned using Resource Certificates to enable verification of
Manifests [RFC6486] and Route Origin Authorizations (ROAs) [RFC6482].
ROAs and Manifests include the Resource Certificates used to verify
them.

Figure 1
This document defines another type of Resource Certificate, which is
referred to as a "BGPsec Router Certificate". The purpose of this
certificate is explained in Section 1 and falls within the scope of
appropriate uses defined within [RFC6484]. The issuance of BGPsec
Router Certificates has minimal impact on RPKI CAs because the RPKI
CA certificate and CRL profile remain unchanged (i.e., they are as
specified in [RFC6487]). Further, the algorithms used to generate
RPKI CA certificates that issue the BGPsec Router Certificates and
the CRLs necessary to check the validity of the BGPsec Router
Certificates remain unchanged (i.e., they are as specified in
[ID.sidr-rfc6485bis]). The only impact is that RPKI CAs will need to
be able to process a profiled certificate request (see Section 5)
signed with algorithms found in [ID.sidr-bgpsec-algs]. The use of
BGPsec Router Certificates in no way affects RPKI RPs that process
Manifests and ROAs because the public key found in the BGPsec Router
Certificate is used only to verify the signature on the BGPsec

Internet-Draft BGPsec Router PKI Profiles July 21, 2016
certificate request (only CAs process these) and the signature on a
BGPsec Update Message [ID.sidr-bgpsec-protocol] (only BGPsec routers
process these).
This document enumerates only the differences between this profile
and the profile in [RFC6487]. Note that BGPsec Router Certificates
are EE certificates and as such there is no impact on process
described in [RFC6916].
3. Updates to [RFC6487]
3.1 BGPsec Router Certificate Fields
A BGPsec Router Certificate is a valid X.509 public key certificate,
consistent with the PKIX profile [RFC5280], containing the fields
listed in this section. This profile is also based on [RFC6487] and
only the differences between this profile and the profile in
[RFC6487] are specified below.
3.1.1.1. Subject
This field identifies the router to which the certificate has been
issued. Consistent with [RFC6487], only two attributes are allowed
in the Subject field: common name and serial number. Moreover, the
only common name encoding options that are supported are
printableString and UTF8String. For BGPsec Router Certificates, it
is RECOMMENDED that the common name attribute contain the literal
string "ROUTER-" followed by the 32-bit AS Number [RFC3779] encoded
as eight hexadecimal digits and that the serial number attribute
contain the 32-bit BGP Identifier [RFC4271] (i.e., the router ID)
encoded as eight hexadecimal digits. If there is more than one AS
number, the choice of which to include in the common name is at the
discretion of the Issuer. If the same certificate is issued to more
than one router (hence the private key is shared among these
routers), the choice of the router ID used in this name is at the
discretion of the Issuer. Note that router IDs are not guaranteed to
be unique across the Internet, and thus the Subject name in a BGPsec
Router Certificate issued using this convention also is not
guaranteed to be unique across different issuers. However, each
certificate issued by an individual CA MUST contain a Subject name
that is unique within that context.
3.1.2. Subject Public Key Info
Refer to section 3.1 of [ID.sidr-bgpsec-algs].
Reynolds, et al. Expires January 22, 2017 [Page 5]
Internet-Draft BGPsec Router PKI Profiles July 21, 2016
3.1.3. BGPsec Router Certificate Version 3 Extension Fields
3.1.3.1. Basic Constraints
BGPsec speakers are EEs; therefore, the Basic Constraints extension
must not be present, as per [RFC6487].
3.1.3.2. Extended Key Usage
BGPsec Router Certificates MUST include the Extended Key Usage (EKU)
extension. As specified in [RFC6487] this extension MUST be marked
as non-critical. This document defines one EKU for BGPsec Router
Certificates:
id-kp OBJECT IDENTIFIER ::=
{ iso(1) identified-organization(3) dod(6) internet(1)
security(5) mechanisms(5) pkix(7) kp(3) }
id-kp-bgpsec-router OBJECT IDENTIFIER ::= { id-kp 30 }
A BGPsec router MUST require the extended key usage extension to be
present in a BGPsec Router Certificate it receives. If multiple
KeyPurposeId values are included, the BGPsec routers need not
recognize all of them, as long as the required KeyPurposeId value is
present. BGPsec routers MUST reject certificates that do not contain
the BGPsec Router EKU even if they include the anyExtendedKeyUsage
OID defined in [RFC5280].
3.1.3.3. Subject Information Access
This extension is not used in BGPsec Router Certificates. It MUST be
omitted.
3.1.3.4. IP Resources
This extension is not used in BGPsec Router Certificates. It MUST be
omitted.
3.1.3.5. AS Resources
Each BGPsec Router Certificate MUST include the AS Resource
Identifier Delegation extension, as specified in section 4.8.11 of
[RFC6487]. The AS Resource Identifier Delegation extension MUST
include one or more AS numbers, and the "inherit" element MUST NOT be
specified.
3.2. BGPsec Router Certificate Request Profile
Reynolds, et al. Expires January 22, 2017 [Page 6]
Internet-Draft BGPsec Router PKI Profiles July 21, 2016
Refer to section 6 of [RFC6487]. The only differences between this
profile and the profile in [RFC6487] are:
o The Basic Constraints extension:
If included, the CA MUST NOT honor the cA boolean if set to TRUE.
o The Extended Key Usage extension:
If included, id-kp-bgpsec-router MUST be present (see Section
3.1). If included, the CA MUST honor the request for id-kp-
bgpsec-router.
o The Subject Information Access extension:
If included, the CA MUST NOT honor the request to include the
extension.
o The SubjectPublicKeyInfo and PublicKey fields are specified in
[ID.sidr-bgpsec-algs].
o The request is signed with the algorithms specified in [ID.sidr-
bgpsec-algs].
3.3. BGPsec Router Certificate Validation
The validation procedure used for BGPsec Router Certificates is
identical to the validation procedure described in Section 7 of
[RFC6487] (and any RFC that updates this procedure), but using the
constraints applied come from this specification. For example, in
step 3: "the certificate contains all the field that must be present"
- refers to the fields that are required by this specification.
The differences are as follows:
o BGPsec Router Certificates MUST include the BGPsec Router EKU
defined in Section 3.1.3.2.
o BGPsec Router Certificates MUST NOT include the SIA extension.
o BGPsec Router Certificates MUST NOT include the IP Resource
extension.
o BGPsec Router Certificates MUST include the AS Resource Identifier
Delegation extension.
o BGPsec Router Certificate MUST include the "Subject Public Key
Info" described in [ID.sidr-bgpsec-algs] as it updates [ID.sidr-
Reynolds, et al. Expires January 22, 2017 [Page 7]
Internet-Draft BGPsec Router PKI Profiles July 21, 2016
rfc6485bis].
NOTE: The cryptographic algorithms used by BGPsec routers are found
in [ID.sidr-bgpsec-algs]. Currently, the algorithms specified in
[ID.sidr-bgpsec-algs] and [ID.sidr-rfc6485bis] are different. BGPsec
RPs will need to support algorithms that are used to validate BGPsec
signatures as well as the algorithms that are needed to validate
signatures on BGPsec certificates, RPKI CA certificates, and RPKI
CRLs.
3.4. Router Certificates and Signing Functions in the RPKI
As described in Section 1, the primary function of BGPsec route
certificates in the RPKI is for use in the context of certification
of Autonomous System (AS) paths in the Border Gateway Protocol
Security protocol (BGPsec).
The private key associated with a router EE certificate may be used
multiple times in generating signatures in multiple instances of the
BGPsec_Path Attribute Signature Segments [ID.sidr-bgpsec-protocol].
I.e., the BGPsec router certificate is used to validate multiple
signatures.
BGPsec router certificates are stored in the issuing CA's repository,
where a repository following RFC6481 MUST use a .cer filename
extension for the certificate file.
4. Design Notes
The BGPsec Router Certificate profile is based on the Resource
Certificate profile as specified in [ID.sidr-rfc6485bis]. As a
result, many of the design choices herein are a reflection of the
design choices that were taken in that prior work. The reader is
referred to [RFC6484] for a fuller discussion of those choices.
CAs are required by the Certificate Policy (CP) [RFC6484] to issue
properly formed BGPsec Router Certificates regardless of what is
present in the certification request so there is some flexibility
permitted in the certificate requests:
o BGPsec Router Certificates are always EE certificates; therefore,
requests to issue a CA certificate result in EE certificates;
o BGPsec Router Certificates are always EE certificates; therefore,
requests for Key Usage extension values keyCertSign and cRLSign
result in certificates with neither of these values;
o BGPsec Router Certificates always include the BGPsec Rouer EKU
Reynolds, et al. Expires January 22, 2017 [Page 8]
Internet-Draft BGPsec Router PKI Profiles July 21, 2016
value; therefore, request without the value result in certificates
with the value; and,
o BGPsec Router Certificates never include the Subject Information
Access extension; therefore, request with this extension result in
certificates without the extension.
Note that this behavior is similar to the CA including the AS
Resource Identifier Delegation extension in issued BGPsec Router
Certificates despite the fact it is not present in the request.
5. Implementation Considerations
This document permits the operator to include a list of ASNs in a
BGPsec Router Certificate. In that case, the router certificate would
become invalid if any one of the ASNs is removed from any superior CA
certificate along the path to a trust anchor. Operators could choose
to avoid this possibility by issuing a separate BGPsec Router
Certificate for each distinct ASN, so that the router certificates
for ASNs that are retained in the superior CA certificate would
remain valid.
6. Security Considerations
The Security Considerations of [RFC6487] apply.
A BGPsec Router Certificate will fail RPKI validation, as defined in
[RFC6487], because the algorithm suite is different. Consequently, a
RP needs to identify the EKU to determine the appropriate Validation
constraint.
A BGPsec Router Certificate is an extension of the RPKI [RFC6480] to
encompass routers. It is a building block BGPsec and is used to
validate signatures on BGPsec Signature-Segment origination of
Signed-Path segments [ID.sidr-bgpsec-protocol]. Thus its essential
security function is the secure binding of one or more AS numbers to
a public key, consistent with the RPKI allocation/assignment
hierarchy.
Hash functions [ID.sidr-bgpsec-algs] are used when generating the two
key identifiers extension included in BGPsec certificates. However
as noted in [RFC6818], collision resistance is not a required
property of one-way hash functions when used to generate key
identifiers. Regardless, hash collisions are possible and if
detected an operator should be alerted.
7. IANA Considerations
Reynolds, et al. Expires January 22, 2017 [Page 9]
Internet-Draft BGPsec Router PKI Profiles July 21, 2016
This document makes use of two object identifiers in the SMI Registry
for PKIX. One is for the ASN.1 module in Appendix A and it comes
from the SMI Security for PKIX Module Identifier IANA registry (id-
mod-bgpsec-eku). The other is for the BGPsec router EKU defined in
Section 3.1.3.2 and Appendix A and it comes from the SMI Security for
PKIX Extended Key Purpose IANA registry. These OIDs were assigned
before management of the PKIX Arc was handed to IANA. No IANA
allocations are request of IANA, but please update the references in
those registries when this document is published by the RFC editor.
