TG9 Proposed document changes
Nov 2013 TG9 Proposed document changes Dallas, TX November 12, 2013 Robert Moskowitz, Verizon

Address Format Current Proposed Nov 2013
Long addresses SHOULD be used when the KMP is performed to establish an SA. Short address MAY be used when the KMP updates an existing SA. Proposed The SA is associated with the long addresses. Thus long addresses SHOULD be transmitted when the KMP is performed to establish an SA. Short address MAY be transmitted when the KMP updates an existing SA. Robert Moskowitz, Verizon

ACK is no proof of processing
Nov 2013 ACK is no proof of processing Current As Key Management payloads may exceed the MPDU, a simple frame chaining method using Forced ACKs will provide the needed fragmentation support. The use of the Forced ACKs allow the sending device to be assured the receiving device has all the frames to reassemble the Key Management payload. Sending lost frames is handled within the MAC and not apparent to the KMP transport. The receiving side MUST anticipate duplicate frames if its ACK was lost. This behavior is accommodated within state machines. Robert Moskowitz, Verizon

ACK is no proof of processing
Nov 2013 ACK is no proof of processing Additional text If a fragment is lost, that is, the inbound state machine registers a skipped fragment, then the inbound processing fails; this is considered an acceptable behavior. A KMP SHOULD be able to handle a lost message, therefore no effort will be made to recover a loss fragment. Robert Moskowitz, Verizon

Security Associations
Nov 2013 Security Associations Additional text Many types of security associations are possible as described in the Security-related MAC PIB attributes section in and An implementer of this recommended practice will select from the options allowed to request the KMP higher layer to establish the desired SA and provide the necessary keys to the MAC PIB.

More on ACKs Current Proposed Nov 2013
a simple frame chaining method using Forced ACKs will provide the needed fragmentation support. The use of the Forced ACKs allow the sending device to be assured the receiving device has all the frames to reassemble Proposed a simple frame chaining method using the MAC Acknowledgment Frame will provide the needed fragmentation support. The use of the MAC Acknowledgment Frame allow the sending device to be assured the receiving device has all the frames to reassemble Robert Moskowitz, Verizon
