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.

first: { iso (1) identified-organization (3) thawte (101) 100 }
last: { iso (1) identified-organization (3) thawte (101) 127 }
          

The donated range from DigiCert, Inc. is:

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-EdDSA25519-ph [I-D.ietf-curdle-pkix-03]
115 Reserved for id-EdDSA448-ph [I-D.ietf-curdle-pkix-03]
128 and up Retained by Digicert [I-D.ietf-curdle-pkix]

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.
