3 21-07-0344-00-00003 Outlines Three meeting slots: Sep. 17 (Mon) PM2, Sep. 19 (Wed) PM1 and PM2 Officers Chair Election: A SG Roll Call vote was taken Voting result: Yoshihiro Ohba:36, Srinivas Sreemanthula:15, Clint Chaplin:6 The election result was affirmed by the WG unanimous Editor: Marc Meylemans (appointed by Chair) Looking for Secretary 7 technical contributions, all falling within the two problems: Problem 1: Security Signaling Optimization during Handover Problem 2: MIH-level Security Mechanism Agreement on Table of Contents of TR (Technical Report) document Agreement on Milestones

4 21-07-0344-00-00004 Problem 1: Security Signaling Optimization during Handover The purpose is to minimize handover signaling latency related to network access authentication and key management Support for inter-technology handover and inter-domain handover Three types of handovers in terms of security signaling: Authentication-based handovers Key Hierarchy based handovers Ticket-based handovers Clear work separation from IETF HOKEY WG is needed

5 21-07-0344-00-00005 Problem 2: MIH-Level Security Mechanism The purpose is to define a mechanism to secure MIH protocol signaling within MIH protocol in order to eventually realize flexible access control for MIH services in a secure manner One typical use case is to provide different pieces of information on neighboring networks depending on the subscription policies of the user All MIH Services (i.e., Event Service, Command Service and Information Service) are part of the Problem

6 21-07-0344-00-00006 Summary on the Technical Contributions http://www.ieee802.org/21/doctree/Security_SG/21-07-0297-02-0000-MIH%20security%20approaches.ppt Detailed explanation on the two Problems http://www.ieee802.org/21/doctree/Security_SG/21-07-0291-00-0000-hokey-preauth-ps.ppt Explanation on IETF HOKEY EAP pre-authentication problem statement draft http://www.ieee802.org/21/doctree/Security_SG/21-07-0301-00-0000-Security_Architecture.ppt Focused on authentication-based handovers for Problem 1 Mapping to existing 802.21 communication model is described Needs study on technical feasibility study on non-EAP authentication Needs study on the potential impact on existing link-layer technologies http://www.ieee802.org/21/doctree/Security_SG/21-07-0299-00-0000-Security-SG-Scenarios.ppt One Use Case for utilizing existing SA across multiple PoAs for Problem 1 One Use Case relating to Multi-Radio Power Management work is identified for Problem 2 http://www.ieee802.org/21/doctree/Security_SG/21-07-0299-00-0000-Fast_re-Authentication_Protocol.ppt Proposal on ticket-based handovers for inter-domain handovers for Problem 1 http://www.ieee802.org/21/doctree/Security_SG/21-07-0310-00-0000-MIH-Security-Options.ppt Solid Use Cases on Problem 2 Some Use Case requires server-only authentication while others do mutual authentication Some Use Case is tightly coupled with network access authentication while others are independent of network access authentication http://www.ieee802.org/21/doctree/Security_SG/21-07-0302-01-0000- MIH_Security_Technical_Requirements_Skeleton.doc Agreement on Table of Contents of TR Agreement on the need for SG agreement on Use Cases for any contribution to get included in TR

7 21-07-0344-00-00007 Security SG Milestones November 2007 All contributions intended to be included in the TR need to be submitted before the meeting Detailed submission guidelines will be posted to the reflector PAR/5C discussion January 2008 All major studies are expected to be done PAR/5C discussion February 2008 Submit PAR/5C to IEEE 802 EC to create a TG March 2008 Completion of TR Discuss feedback on PAR/5C
