August 2018IANA Registration forthe Cryptographic Algorithm Object Identifier RangeAbstract   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 donated range and the identifiers that were   assigned from that range, transfers control of that range to IANA,   and establishes IANA allocation policies for any future assignments   within that range.Status of This Memo   This document is not an Internet Standards Track specification; it is   published for informational purposes.

Introduction   When the Curdle Security Working Group was chartered, a range of   object identifiers was donated to the working group by DigiCert, Inc.   The use of these object identifiers allowed for the Edwards Elliptic   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.  The initial   registrations from this arc were made while developing [RFC8410].   After those registrations were made, there were still some unused   values that could be used by 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.Schaad & Andrews              Informational                     [Page 2]

RFC 8411                      OID Registry                   August 2018   The donated range from DigiCert, Inc. is as follows:   first: { iso (1) identified-organization (3) thawte (101) 100 }   last: { iso (1) identified-organization (3) thawte (101) 127 }2.  IANA Considerations   IANA has created the "SMI Security for Cryptographic Algorithms"   registry within the SMI-numbers registry.  The new registry has three   columns, as shown below.     +------------+-------------------------------+-----------------+     | Decimal    | Description                   | References      |     +------------+-------------------------------+-----------------+     | 0-99       | Retained by DigiCert          |RFC 8411        |     | 100        | Reserved for child reg        |RFC 8411        |     | 110        | id-X25519                     | [RFC8410]       |     | 111        | id-X448                       | [RFC8410]       |     | 112        | id-EdDSA25519                 | [RFC8410]       |     | 113        | id-EdDSA448                   | [RFC8410]       |     | 114        | Reserved for id-EdDSA25519-ph | [SAFE-X.509-03] |     | 115        | Reserved for id-EdDSA448-ph   | [SAFE-X.509-03] |     | 128 and up | Retained by DigiCert          |RFC 8411        |     +------------+-------------------------------+-----------------+            Table 1: SMI Security for Cryptographic Algorithms   The registration policy is "Specification Required" as defined in   [RFC8126].   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.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.Schaad & Andrews              Informational                     [Page 3]

At the time of the donation, the root of the range   was assigned to Symantec but has since been transferred to DigiCert.
