Object Identifier Registry for the
Long-Term Archive and Notary Services (LTANS) Working Group
Abstract
When the Long-Term Archive and Notary Services (LTANS) working group
was chartered, an object identifier arc was set aside for use by that
working group. This document describes the object identifiers that
were assigned, and it establishes IANA allocation policies for any
future assignments within that arc.

1. Introduction
When the Long-Term Archive and Notary Services (LTANS) working group was chartered, an object identifier arc was set aside for use by that working group. These object identifiers are primarily used with Abstract Syntax Notation One (ASN.1) [ASN1-88] [ASN1-97].
The LTANS object identifier arc is:
id-ltans OBJECT IDENTIFIER ::= { iso(1) identified-organization(3)
dod(6) internet(1) security(5)
mechanisms(5) ltans(11) }
This document describes the object identifiers that were assigned,
and it establishes IANA allocation policies for any future
assignments within that arc.
2. Subordinate Object Identifier Arcs
Three subordinate object identifier arcs were used. The first arc, id-mod, was used to assign ASN.1 module identifiers. The second arc, id-ct, was used to assign Cryptographic Message Syntax (CMS) content types. The third arc, id-em, was set aside for Evidence Record Syntax (ERS) encryption methods.
id-mod OBJECT IDENTIFIER ::= { id-ltans 0 }
id-ct OBJECT IDENTIFIER ::= { id-ltans 1 }
id-em OBJECT IDENTIFIER ::= { id-ltans 2 }
Housley Informational [Page 2] RFC 7036 LTANS OID Registry October 2013
3. Module Identifiers
The Evidence Record Syntax (ERS) [RFC4998] includes two ASN.1 modules. Both modules define the same syntax, but one module uses the 1997 ASN.1 syntax, and the other module uses the 1988 ASN.1 syntax. These module identifiers are:
id-mod-ers OBJECT IDENTIFIER ::= { id-mod 1 }
id-mod-ers-v1 OBJECT IDENTIFIER ::= { id-mod 1 1 }
id-mod-ers88 OBJECT IDENTIFIER ::= { id-mod 2 }
id-mod-ers88-v1 OBJECT IDENTIFIER ::= { id-mod 2 1 }
The Long-term Archive Protocol (LTAP) [LTAP] includes two ASN.1 modules. While this protocol was never published as an RFC, the module identifiers were assigned to facilitate implementation. Both modules define the same syntax, but one module uses the 1997 ASN.1 syntax, and the other module uses the 1988 ASN.1 syntax. These module identifiers are:
id-mod-ltap88 OBJECT IDENTIFIER ::= { id-mod 3 }
id-mod-ltap88-v0 OBJECT IDENTIFIER ::= { id-mod 3 0 }
id-mod-ltap88-v1 OBJECT IDENTIFIER ::= { id-mod 3 1 }
id-mod-ltap OBJECT IDENTIFIER ::= { id-mod 4 }
id-mod-ltap-v0 OBJECT IDENTIFIER ::= { id-mod 4 0 }
id-mod-ltap-v1 OBJECT IDENTIFIER ::= { id-mod 4 1 }
The document that describes the conventions for using the Server- Based Certificate Validation Protocol (SCVP) to convey Long-Term Evidence Records [RFC5276] includes one ASN.1 module. The module identifier is:
id-mod-ers-scvp OBJECT IDENTIFIER ::= { id-mod 5 }
id-mod-ers-scvp-v1 OBJECT IDENTIFIER ::= { id-mod 5 1 }
The Data Structure for the Security Suitability of Cryptographic Algorithms (DSSC) [RFC5698] includes two ASN.1 modules. Both modules define the same syntax, but one module uses the 1997 ASN.1 syntax, and the other module uses the 1988 ASN.1 syntax. These module identifiers are:
id-mod-dssc88 OBJECT IDENTIFIER ::= { id-mod 6 }
id-mod-dssc88-v1 OBJECT IDENTIFIER ::= { id-mod 6 1 }
id-mod-dssc OBJECT IDENTIFIER ::= { id-mod 7 }
id-mod-dssc-v1 OBJECT IDENTIFIER ::= { id-mod 7 1 }
Housley Informational [Page 3] RFC 7036 LTANS OID Registry October 2013
4. CMS Content Types
A CMS content type for an Evidence Record was reserved, but no specification points to this value. It remains reserved.
id-ct-evidence-record OBJECT IDENTIFIER ::= { id-ct 1 }
The Data Structure for the Security Suitability of Cryptographic Algorithms (DSSC) [RFC5698] specifies three CMS content types. These CMS content types are:
id-ct-dssc-asn1 OBJECT IDENTIFIER ::= { id-ct 2 }
id-ct-dssc-xml OBJECT IDENTIFIER ::= { id-ct 3 }
id-ct-dssc-tbsPolicy OBJECT IDENTIFIER ::= { id-ct 6 }
The Long-term Archive Protocol (LTAP) [LTAP] defines two CMS content types. While this protocol was never published as an RFC, the CMS content types were assigned to facilitate implementation. These CMS content types are:
id-ct-LTAPRequest OBJECT IDENTIFIER ::= { id-ct 4 }
id-ct-LTAPResponse OBJECT IDENTIFIER ::= { id-ct 5 }
5. ERS Encryption Methods
An arc was set up for Evidence Record Syntax (ERS) encryption methods, and one object identifier was assigned. However, that object identifier is obsolete, and it should not be used.
id-em-enveloped-data OBJECT IDENTIFIER ::= { id-em 1 } -- obsolete
6. 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.
7. IANA Considerations
IANA has updated one registry table and created four additional tables.
Updates to the four new tables require Expert Review, as defined in [RFC5226]. The Designated Expert is expected to ensure that any new values are strongly related to the work that was done by the LTANS WG. Object identifiers for other purposes should not be assigned in this arc.
