To make sure I’m following along, to address the "Updates: 3779, 6484, 6487 (if
approved)" changes would the follow changes work:
0) RFC6484-related changes
If we’re going with two OIDs (one for the original “strict" validation and one
for new “relaxed” validation), then I’m hoping that we can just define a new
OID in s1.2 of RFC 6484 and be done with it (i.e., I hope we don’t also have to
update s4.1.1, s4.5.1, and s4.7.1 where RFC 3779 is mentioned). Here’s some
text for a new section:
#.# Updates to RFC 6484
This section replaces s1.2 of [RFC6484] with the following:
The name of this document is "Certificate Policy (CP) for the Resource PKI
(RPKI)”.
This policy has been assigned the following two OIDs:
id-cp-ipAddr-asNumber OBJECT IDENTIFIER ::= { iso(1)
identified-organization(3) dod(6) internet(1)
security(5) mechanisms(5) pkix(7) cp(14) 2 }
id-cp-ipAddr-asNumber-v2 OBJECT IDENTIFIER ::= { iso(1)
identified-organization(3) dod(6) internet(1)
security(5) mechanisms(5) pkix(7) cp(14) TBD }
id-cp-ipAddr-asNumber and the extensions defined in [RFC3779] indicate that the
original certification path validation rules are to be used.
id-cp-ipAddr-asNumber-v2 and the extensions defined in [this document] indicate
that the validation reconsidered certification path validation rules defined in
[this document] are to be used.
1) IANA registrations
We need to register some OIDs with IANA. Here’s an IANA considerations section
(assumes we’re registering a new CP OID - [] references will be to whatever
section # it ends up being):
6. IANA Considerations
IANA is to register the following five OIDs:
- id-cp-ipAddr-asNumber-v2 from [insert Section and #] in the SMI Security for
PKIX Certificate Policies registry.
- id-pe-ipAddrBlocks-v2 and id-pe-autonomousSysIds-v2 from [insert Section and
#] in the SMI Security for PKIX Certificate Extension registry.
- IPAddrAndASCertExtn-v2 and IPAddrAndASCertExtn-2010v2 from [insert Section
and #] in the SMI Security for PKIX Module Identifier registry.
RFC EDITOR: There are two ASN.1 modules both include the same assignments for
id-pe-ipAddrBlocks-v2 and id-pe-autonomousSysIds-v2, i.e., the assignments are
made by IANA once and the values are included in the two modules. Please
delete this prior to publication.
2) RFC3799-related changes
As far as RFC 3779 updates go, we probably need to update s2.3 and s3.3 as well
as add new ASN.1 modules.
2.1) I haven’t got text off the top of my head for the s2.3 and s3.3 changes.
2.2) As far as the ASN.1-related changes go here’s two ASN.1 module(s). The
modules define the new OIDs and imports the syntax from RFC3779/RFC6268. The
basic idea is to keep the modules as short as possible. The 2nd module is for
the ’08 ASN.1 that was defined in RFC 6268 to be used with RFC5911/5912.

2.3) If we want to be really ambitious, then right after the ASN.1 modules are
included in the draft we could request the WG chairs start an early IANA
allocation request for these OID ;)
Cheers,
