You can collapse wpa, wpa2 and wpa2 with preauth. wpa and wpa2 are both actually trademarked terms of the Wi-Fi Alliance so they should probably not be in an IANA registry anyway. Regardless, though, they all do the same thing by conveying the same type of information in the same way. 802.11s specifies a password-based authentication scheme that does not use EAP so there doesn't seem to be a reason to define an "EAP lower layer" for 802.11s. 802.11r does things a little differently-- a key hierarchy is built up and keys are distributed hither and yon-- so it might be good to channel bind that stuff but 802.11r has been rolled into the 802.11 standard (there is no stand-alone reference for 802.11r, by the way) and can be dealt with as just 802.11. All the "information elements" that specify that 11r-specific stuff is being communicated are defined by 802.11's Assigned Number Authority and their communication is done in the same fashion as plain-jane 802.11 (aka wpa and wpa2). If "information elements" for 802.11r are included in the 802.11 channel binding data then it means the session is going to be used for 802.11r-type stuff. Values 4-8 in the table in section 11.1 can all be combined into a single value named "802.11" with a reference to IEEE 802.11-2007. regards, Dan. _______________________________________________ Emu mailing list Emu@ietf.org https://www.ietf.org/mailman/listinfo/emu
