IANA Registration for new Cryptographic Algorithm Object Identifier
Range
draft-schaad-curdle-oid-registry-03
Abstract
When the Curdle Security Working Group was chartered, a range of
object identifiers was donated by DigiCert, Inc. for the purpose of
registering the Edwards Elliptic Curve key agreement and signature
algorithms. This donated set of OIDs allowed for shorter values than
would be possible using the existing S/MIME or PKIX arcs. This
document describes the range of identifiers that were assigned in
that donated range, transfers control of that range to IANA, and
establishes IANA allocation policies for any future assignments
within that range.

1. Introduction
When the Curdle Security Working Group was chartered, a range of
object identifiers was donated by DigiCert, Inc. for use by that
working group. The use of these object identifiers allowed for the
Edwards Ellitptic Curve key agreement [RFC7748] and signature
[RFC8032] algorithms to be defined with encodings that are smaller
than similar ones would be if assigned from the existing S/MIME or
PKIX arcs. These initial registrations from this arc were done while
developing [I-D.ietf-curdle-pkix]. After those registrations were
done, there were still some unused values that can be used for other
security groups.
Object identifiers are primarily used with Abstract Syntax Notation
(ASN.1) [ASN.1]. The ASN.1 specifications continue to evolve, but
object identifiers can be used with any and all versions of ASN.1.
This document describes the object identifiers that were assigned in
that donated range, transfers control of the range to IANA, and
establishes IANA allocation policies for any future assignments.

Internet-Draft OID Registry January 2018
The donated range from DigiCert, Inc. is:
first: { iso (1) identified-organization (3) thawte (101) 100 }
last: { iso (1) identified-organization (3) thawte (101) 127 }
2. IANA Considerations
IANA is asked to create one new registry table.
2.1. "SMI Security for Cryptographic Algorithms" Registry
Within the SMI-numbers registry, add an "SMI Security for
Cryptographic Algorithms" table with the three columns:
+-----------+---------------------------+---------------------------+
| Decimal | Description | References |
+-----------+---------------------------+---------------------------+
| 0 - 99 | Retained by Digicert | [I-D.ietf-curdle-pkix] |
| | | |
| 100 | Reserved for child reg | |
| | | |
| 110 | id-X25519 | [I-D.ietf-curdle-pkix] |
| | | |
| 111 | id-X448 | [I-D.ietf-curdle-pkix] |
| | | |
| 112 | id-EdDSA25519 | [I-D.ietf-curdle-pkix] |
| | | |
| 113 | id-EdDSA448 | [I-D.ietf-curdle-pkix] |
| | | |
| 114 | Reserved for id- | [I-D.ietf-curdle-pkix-03] |
| | EdDSA25519-ph | |
| | | |
| 115 | Reserved for id- | [I-D.ietf-curdle-pkix-03] |
| | EdDSA448-ph | |
| | | |
| 128 and | Retained by Digicert | [I-D.ietf-curdle-pkix] |
| up | | |
+-----------+---------------------------+---------------------------+
The column 'Decimal' is required to be a number between 100 and 127
inclusive.
The value of 100 has been reserved so that a new arc below that point
can be established in the future. (I.e. starting at 1.3.101.100.1)
If the new child registry is established, a name for this value is to
be assigned at that point. The experts can, at their discretion,
assign an algorithm OID instead.

The registry is to be created using the "Specification Required"
policy as defined in [RFC8126].
3. Security Considerations
This document populates an IANA registry, and it raises no new
security considerations. The protocols that specify these values
include the security considerations associated with their usage.

Acknowledgments
Our thanks go out to DigiCert for donating the range of OIDs covered
in this document. At the time of the donation, the root of the range
was assigned to Symantec but has sense been transfered DigiCert.
This document uses a lot of text from a similar document by Russ
Housley. Copying always makes things easier and less error prone.
