Summary of Updates to Abbreviated Handshake March 2009 Summary of Updates to Abbreviated Handshake Date: 2009-03-06 Meiyuan Zhao, Intel

March 2009 Abstract This document summarizes the several changes to the Abbreviated Handshake specification Normative text in doc.:11-09/0266r0 and corresponding comment spreadsheet in doc.:11-09/0267r0 Note: adoption of 11-09/0266r0 depends on the adoption of Mesh Peering Instance Controller (11-09/0287r0) Meiyuan Zhao, Intel

Major Changes Moved AbbrHS FSM to SME (CIDs 190, 212) March 2009 Major Changes Moved AbbrHS FSM to SME (CIDs 190, 212) Update PMK selection procedure (CIDs 204, 226, 1254) Remove AKM suite selection and KDF selection (CIDs 193, 205) Resolve AbbrHS and PLM interaction (CIDs 187, 209) Meiyuan Zhao, Intel

Move AbbrHS to SME AbbrHS is for peering management and key management March 2009 Move AbbrHS to SME AbbrHS is for peering management and key management Peering Management Protocol now in SME Security associations are managed in SME Updates Remove unnecessary MLME primitives Update FSM specification accordingly CIDs: 190, 212 Meiyuan Zhao, Intel

Update PMK Selection Reasons Update CIDs March 2009 Update PMK Selection Reasons MKD domains removed with MSA protocols Each pair of mesh STAs should share at most one valid PMK Text to be added to specify protocol interactions (SAE and AbbrHS) and PMKSA requirements PMK selection using two lists is no longer a valid case Update Single value confirmation using Peering Open and Peering Confirm Update FSM specification accordingly (remove MESH_ALT_KEY status code) CIDs 204, 226, 1254 Meiyuan Zhao, Intel

Update AKM and KDF Selection March 2009 Update AKM and KDF Selection Issues AKM should include KDF AKMP in fact is part of PMKSA SAE should be updated to specify how to reach agreement on AKMP Protocol interaction between SAE and AbbrHS should be updated accordingly Update Remove AKM selection and KDF selection Remove NOAKM_RJCT and NOKDF_RJCT events from FSM CIDs 193, 205 Meiyuan Zhao, Intel

Update AbbrHS and PLM Interaction March 2009 Update AbbrHS and PLM Interaction Issue: Both protocols use Peering Management frames that cause ambiguity in protocol initiation Update Add a new “Mesh Peering Protocol Version” information element in all Peering Management frames Define two values: “Peering Management Protocol” and “Abbreviated Handshake Protocol” CIDs 187, 209 Meiyuan Zhao, Intel

Update FSM Specification March 2009 Update FSM Specification Update Remove CNF_ACPT event from CNF_RCVD state Add OPN_ACPT event in OPN_RCVD state PLM should be updated too Remove NOAKM_RJCT and NOKDF_RJCT events Update FSM to work with Mesh Peering Instance Controller Remove LISTEN state Remove NOKEY_RJCT event CIDs 165, 171, 210 Meiyuan Zhao, Intel

Other Changes Update GTK wrapping (CIDs 200, 202) March 2009 Other Changes Update GTK wrapping (CIDs 200, 202) Add lifetime in wrapped GTK key material Add specification on update GTK upon expiry Remove “echo” of received GTK in Peering Confirm frame Clean up frame processing (CIDs 189, 207) Misc frame formating update Remove V.5 (CIDs 217, 218, 220) Require substantial update to reflect normative text Served purpose of educating readers Meiyuan Zhao, Intel
