  1. Progress on OID Resolution System Jun Seob LEE (juns@etri.re.rk) Document number Zhangjiajia, China 8-10 April 2009

  2. Contents Concept History Contents of 2nd Working Draft Issues

  3. 1. Concept of OID Resolution System • Object Identifier (OID) • Definition: A globally unique value associated with an object to unambiguously identify it (ITU-T Recommendation X.680 | ISO/IEC 8824-1) • Variety of objects:ITU-T SG no., countries, Standards, cryptographic algorithm, network, protocol commend, code … Anything • Example • {0 1 17} = ITU-T Study Group 17 • {1 0 15961} = ISO/IEC 15961 • {1 2 410 200004 1 2} = HAS-160 hash algorithm • {0 3 4500} = Korea (Rep. of) HiNET-P (Korea Telecom) • {1 0 15961 126 7} = ReadSingleObjectCommand • OID Resolution System • Definition: A system which provides information associated with any object identified by an Object Identifier

  4. 2. History (1/2) • During the discussion on ITU-T restructuring, new ToR, OID resolution, is added to Q.10 (Q.12) • NP (6N13665) was proposed at July 2008 • NP was approved at October 2008 • JTC 1/SC 6 meeting (Montreux , 3 ~ 7 November 2008) • Project No. (55.01.00) and designate IS no. (29168) were assigned • BRM for NP ballot • 1st Working Draft was submitted to JTC 1/SC 6 at December 2008 • ITU-T SG17 meeting (Geneva, 11 ~ 20 February 2009) • BRM on 1st Working Draft • 2nd Working Draft was submitted to JTC 1/SC 6 at 31 March

  5. 2. History (2/2) • Project editors (both ITU-T SG17 and JTC 1/SC 6) • Mr. Jun Seob LEE (juns@etri.re.kr, Korea) • Ms. Xu Donmei (xudm@cesi.ac.cn, China) • Prof. Byoung-Ho Ahn (bhahn@ok.ac.kr, Korea)

  6. 3. Contents of 2nd Working Draft (1/3) • Title: Object Identifier Resolution System • Contents • OID Resolution System Architecture • Overview • General OID resolution process • Application-specific OID resolution process • The DNS protocol for the general OID resolution process • Query to an OID resolution server • Response from the OID resolution server • Operation of the OID Resolution System • Name space for OID Resolution System • Default setting of zone file for OID Resolution System • Security and Trust Aspects of the OID Resolution System

  7. 3. Contents of 2nd Working Draft (2/3) • Overview of OID Resolution System

  8. 3. Contents of 2nd Working Draft (3/3) • Input to OID resolution server • Canonical form of OID-IRI (ex, /2/27/1) • OID-IRI (ex, /joint-iso-itu-t/tag-based/mcode) • Output from OID resolution server • Access information • Access method and location (ex, HTTP, www.example.com) • Child node information (TBD) • Canonical form of an OID-IRI (ex, /2/27/1)

  9. 4. Issues • Name space for OID Resolution System • New gTLD for OID Resolution System • .oid, oid.itu.int, oid.int … • Default setting of zone file • Security issues • DNSsec
