21-07-xxxx NSIS WG GIST draft failed to pass IESG evaluation IESG evaluation ( “Yes” or “No-Objection”: 8 “Discuss”: 2 “Abstain”: 6 Unvoted: 3 “Yes" or "No-Objection" positions from 2/3 of non-recused ADs, with no "Discuss" positions, are needed for approval The draft needs to go through a new WG last call and IETF last call to be a Proposed Standard RFC

21-07-xxxx MIPSHOP WG “Mobility Services Transport: Problem Statement” draft WG Last Call completed in May The latest draft: A liaison statement sent to MIPSHOP Purpose: to encourage and accelerate the DT work Transport solution: Design team report in IETF68 in March Identified three major issues: Layer Split between MSTP and MSTP User (e.g., MIHF and MIH User) Node Discovery (possibility of multiple discovery options) and Message Routing (multi-hop related issue) Security and Resilience The DT is still discussing design issues Progress of the work is slower than expected Further update to be reported in IETF69, including today’s discussion points on MIH transport

21-07-xxxx HOKEY WG HOKEY started to work on a 3-party key distribution protocol draft-ietf-hokey-key-mgm-00.txt HOKEY re-authentication solution draft became a WG draft draft-ietf-hokey-erx-03.txt There are inconsistency among HOKEY WG drafts in terms of Key hierarchy (USRK, DSRK, USDSRK) Different key hierarchy definitions in emsk-hierarchy draft and key-mgm draft Key distribution mechanism hokey-erx draft does not follow key distribution mechanism defined in hokey-key- mgm draft Pre-authentication discussion will start from IETF59 Big issue: HOKEY charter does not allow inter-technology pre-auth Problem statement and AAA requirements drafts are still important

21-07-xxxx DNA WG draft-ietf-dna-link-information-06 (Link-layer Event Notifications for Detecting Network Attachments) In RFC editor queue draft-ietf-dna-protocol-06.txt (DNAv6) WG Last Call ended on July 18, 2007

21-07-xxxx Mobility WGs being merged MIP6, NEMO and MONAMI6 WGs are being merged into a new single WG, MEXT (Mobility EXTentions for IPv6) Mailing list: Waiting for WG creation approval from IESG Three purposes: (A) enhance base IPv6 mobility by continuing work on developments that are required for wide-scale deployments and specific deployment scenarios (B) the working group will ensure that any issues identified by implementation and interoperability experience are addressed, and that the base specifications are maintained (C) The group will also produce informational documentation, such as design rationale documents or description of specific issues within the protocol
