Patent Policy and Procedures: The contributor is familiar with the IEEE 802 Patent Policy and Procedures <http:// ieee802.org/guides/bylaws/sb-bylaws.pdf>, including the statement "IEEE standards may include the known use of patent(s), including patent applications, provided the IEEE receives assurance from the patent holder or applicant with respect to patents essential for compliance with both mandatory and optional portions of the standard." Early disclosure to the Working Group of patent information that might be relevant to the standard is essential to reduce the possibility for delays in the development process and increase the likelihood that the draft publication will be approved for publication. Please notify the Chair <[email protected]> as early as possible, in written or electronic form, if patented technology (or technology under patent application) might be incorporated into a draft standard being developed within the IEEE 802.11 Working Group.

Submission
Proposed Changes to D0.00• Numerous re-wordings need to increase clarity of
the text. • Level numbers of keys:
– PMK-R0 is top level, PMK-R1 is second level, PMK-R2 is third level, PTK is fourth level.
• Description of Count Information Element– The number of IEs protected by the MIC in the
EAPKIE (this IE, and succeeding IEs up through and including the EAPKIE).
– See 7.3.2.28 for definition, and Table 9 in 7.2.3.6 for sample usage

Submission
Proposed Changes to D0.00, cont.
• TGr Key Hierarchy replaced by FBT Key Hierarchy
• Uses of “over-the-wire” replaced by “over-the-DS”
• Noted in frame definitions that a RIC is a variable number of information elements.
• Capability advertisement made consistent with frame definitions (but may change with additions to those definitions).

Slide 9
doc.: IEEE 802.11-05/0538r4
Submission
Proposed Changes to D0.00, cont.• Definition of “Security Domain” changed to be based on
“holders of keys derived from PMK-R0” instead of “R0 key holder children” (which was never defined).
• Security Domain “contained within” a Security Mobility Domain, and not “a member of” a Security Mobility Domain. A SMD being “a set of sets” adds only confusion, and is not consistent with 8A.5.7.
• (Possibly(?) technical) qualified a statement that a QSTA must associate with a new AP prior to requesting resources (Section 5.4.5.1.2) with “In a non-FBT environment”.
• After the FBT sequence, and before reassociation, resources are reserved for a “limited” but not a “fixed” length of time.

doc.: IEEE 802.11-05/0538r4
Submission
Proposed Changes to D0.00, cont.
• Communication between Current AP and Target AP consistently “out of scope” (as in the majority of cases) and not TBD (as in some cases).
• Text referring to “Action messages” generalized to “Request messages”, since not all FBT sequences will be using the FT-Action messages.
• In following the lead of Supplicant/Authenticator instead of STA/AP, made several refs for QoS to “Resource Requestor” instead of STA. More needed.
• Algorithm for RIC processing by AP changed to note success and failure status.

Submission
Proposed Changes to D0.00, cont.
• Added 11p (in addition to 11e and 11k) as specs we will be following to revcom
• Re-checked section numbering, figure numbering, table numbering
• “a STA” and “an RSN” and “an RSNA”
