Proposal for OID-based M 2 M Node ID Group Name: WG 2 Architecture at TP#8 (Miyazaki, December 2013) Source: Yong-Suk Park, KETI, yspark@keti. re. kr Meeting Date: 2013 -12 -09 Agenda Item: TBD (Contribution on M 2 M Node ID)

What is OID? • OID (Object Identifier) – A globally unique value associated with an object to unambiguously identify it (ITU-T Recommendation X. 680|ISO/IEC 8824 -1) • Object Types – ITU-T SG(Study Group) number, country, standard, encryption algorithm, network, protocol command, etc. Anything • • • {0 1 17} = ITU-T Study Group 17 {1 2 410} = Korea {1 0 15961} = ISO/IEC 15961 {1 2 410 200004 1 2} = HAS-160 hash algorithm {0 3 4500} = Korea (Rep. of) Hi.

OID Structure • Hierarchical structure based on the “OID Trees” • Root is unnamed. The first arc consists of 3 values: 0, 1, 2 • Each arc is managed individually or jointly by international standards bodies Root Arc 1 st Arc 2 nd Arc 3 rd Arc 0 (ITU-T) 1 2 450 481 1 (ISO) . . . 40 1 2 2 (Joint ISO/ITU-T) . . . 40 410 1 27 . . . 40 1 An “Arc” is a placeholder for representation in the OID hierarchical tree structure and the number of digits in each “Arc “ is variable. © 2013 one.

Why use OID? • Standardized International Identification System – Unlike other identification schemes, OID is a globally unique identification system based on international standard (applicable to any industry, any country) • ITU-T X. 660 | ISO/IEC 9834 -1 (2008), General procedures and top arcs of the ASN. 1 Object Identifier tree • ITU-T X. 662 | ISO/IEC 9834 -3 (2008), Registration of object identifier arcs beneath the top-level arc jointly administered by ISO and ITU-T • ITU-T X. 665 | ISO/IEC 9834 -6 (2004), Registration of application processes and application entities • ITU-T X. 666 | ISO/IEC 9834 -7 (2008), Joint ISO and ITU-T registration of international organizations • Easily expandable due to the hierarchical structure of the OID Tree • The concept of “registration” can be applied to the identifier of a particular object – Conflict between identifiers can be avoided – Enables easy management and control – Infrastructure exists for OID Directory/Resolution (DNS like) © 2013 one.
