Hi Po-kai,

Thanks for presenting this contribution in 11mf.

Here are my personal technical comments on the proposal:

1) The proposed size of the MIC and the PN in protected control frames is in the order of the size of the content of the control frame. Given these frames are transmitted frequently and at lower data rates, they will consume significant medium time. Please consider reducing the size of the frame, by at least, truncating the MIC.

2) Personally, I'm not comfortable using the same TK for data confidentiality and control frame protection. A new TK should be derived for control frame protection given that the purpose is not data confidentiality.

3) Another point that I'd like to echo from Dan is that I don't believe there should be a requirement to use GCMP-256 for control frame encryption. I think we need to be more flexible with cipher suite negotiations.

Cheers,

Mike
