[STDS-802-11-TGBN] 回复: [STDS-802-11-TGBN] Seamless roaming PDT Part 3, Part 4, and Part 5



Hi, Duncan

 

       Thanks for the hard work you have did.

       I have some questions as below.

1.     Part 3 section 37.9.1, P9, the sentence  the component of the 802.1X Authenticator in the SMD-ME interacts with an 802.1X Authenticator component in the AP MLD that manages the 802.1X Controlled Port for the non-AP MLD seems not clear, I suggest that giving the definition and the responsibility of the component of the 802.1X Authenticator in the SMD-ME and the component of the 802.1X Authenticator in the SMD-ME, and how the interacts? Or give a note/reference to help comprehension

2.     SNouce and ANouce are used to derive a new PTK if the Different PTK mode is used in section 37.9.5.3 of part 3. In my understanding, SNouce shall be included in ST preparation request, and ANouce shall be included in ST preparation response, maybe both of them can be included in SMD BSS Transition Parameters element, but it was not mentioned in the other place, so, I suggest add ANouce and SNouce in SMD BSS Transition Parameters element or some other subfield.

3.     Diffie-Hellman Parameter element shall be included optionally in UHR Link Reconfiguration request/Response, add it in the table 9-658bb and table 9-658bc

4.     Section 37.9.5.3, the new PTK is derived in ST preparation stage if the Different PTK mode is used, but there is no PTK confirm stage(verified the Non-AP MLD and target AP MLD share the same new PTK), in my understanding, it can be done in ST execution stage, which means the ST execution shall still be protected by the old PTK, and confirm information shall be included in ST execution request/response, if I am correct, new text shall be add to clarify this. Besides

5.     I suggest adding text to clarify when the new key will be used if the if the Different PTK mode is used

 

 

Cheers
