"802.1x"?

[Mikael Olsson <mikael.olsson () clavister com>]

Hullo,

Could someone clueful please take a minute or two and give us all the
"techecutive summary" of 802.1x?  I've been trying to piece together
what exactly it's supposed to be doing, but everything I've come 
across so far has been so buzzword-laden, it's been impossible to 
glean real clue from.

All I've understood is that it uses PPP EAP for authentication
(by, for instance, talking to a radius server)
- Which box is the "EAP server"?  I would assume that it's the
  endpoing ("base station"), but docs seem to suggest that 
  it just gets passed through to some sever in the background?
- Then there's something about key exchange.... (?)
- Is there a built-in crypto layer, or is that supposed to be 
  done by something else?
- Does it rely on known-good crypto, or are they inventing 
  own algorithms again?
- Is it any good? :)
