  Which message?  The RADIUS packet?  If so, the common term is not
"TEK", but "shared secret".

  Please don't invent phrases or acronyms to describe things.  It wastes
everyone's time.

  Do you mean supplicant?  i.e. PC running Windows?  It's not normally
called "client".

  Something... for what?

  Specification to do... what?

  Perhaps part of the reason why you can't find specifications is you're
using the wrong words to describe things.

  Please go read a few 802.1X "howtos" or guides to learn how it works,
and what the common terminology is.
