excellent video and great work and great contribution also but I have a question, the MSK is sent from the radius server to the supplicant or that are generated locally?

[@GDNetworkingNewbie]

Thanks for your comments, MSK is generated locally at supplicant.

[@the_wizard_exe]

@@GDNetworkingNewbie thank's for your answer !

[@GDNetworkingNewbie]

Thank you Sir.

[@emailajay1]

Great video... I have one question... is the PMK value at the Supplicant and Authenticator has the same value ? Thanks again for the informative video.

[@GDNetworkingNewbie]

I think, it depends, but with PSK implementation, it is same.

[@emailajay1]

@@GDNetworkingNewbie Many thanks for your response. Yeah on the PSK mechanism it is same, as it is pre-shared. But what if we are using EAP-TLS or PEAP-MSCHAPv2 ?
