Not to be confused with WPA2-psk which is like WPA psk but uses aes instead
of TKIP cryptography.

Since there is WPA-PSK and WPA2 often known as Enterprise,
The real difference is that WPA-PSK uses a fixed 'pre-shared' key to
encrypt the link between the AP and the supplicant, Enterprise assumes
that a RADIUS server is available to authenticate the session and set the
key for the session. What has not been discussed is what protocol is
being used for these PEAP and/or EAP-TTLS are valid choices,
The encryption scheme is 'better' on enterprise as the key is not known
before session instantiation, But WPA-PSK (aka Personal) and WPA2 both
use the same cipher set to protect the session so the link is as secure
but if the key is disclosed to unauthorized users the wireless network
effectively has no security whereas WPA2 uses a user database and if the
user's credentials are disclosed the endpoint can be deauthenticated and
the users credentials changed. Whereas WPA-PSK requires reconfiguration
of the AP(s) and supplicant reconfiguration,
Hope this helps

Subject: [c-nsp] Cisco AIRONET WPA-Enterprise w/Windows question..
I have a question hopefully someone can give me a pointer or shed some
light on..
I have both an Aironet 1242AG and now a 1252AG access point, which are
working fine. I have WPA2-Personal with a shared key setup and running
great as well. As it was my impression that Vista and Win7 both
supported
Enterprise authentication, which I figured would be better and more
secure
than using the personal shared key stuff.
I have tried, and googled, and I for the life of me just can't seem to
get
Enterprise auth going.. Does anyone have any docs on getting the
Aironet
and Windows to play together, configs, or links to info that will help?
Just FYI, I am trying to use the radius server built into the AP, as I
figured that would be simple enough, hopefully doing that is ok..
