Does EAP/LEAP encrypt the wireless authentication to the AP or the entire session? In other words after you are authenticated is the data being sent through the air encrypted? i.e. Web traffic, e-mail

Hi
Leap / EAP is framework of protocol between Users , Radius Server and AP .
It authenitcates users via Radius server .
It generates DYNAMIC KEY to encrypt the ALL DATA traffic .
so you can have centralised database and dynamic Key . You don't have to
manage the key in this process .
So all traffic is encrypted between AP and client .
Above white paper explains in detail

YES..All the data between Wireless Client and Access point will be encrypted.
So data between Wireless LAN devices will be encrypted. Visit

On the client, if I am using LEAP, do I need to setup a encryption key? What is it used for? Is it dynamic like the unicast key provided from the RADUIS server? Does PEAP support the same dynamic environment that LEAP does.
Thanks,

If using LEAP, you need not to put the static WEP on the client. The WEP key fields are greyed out. EACH client will receive UNIQUE dynamic WEP key per session from the RADIUS. You can strengthen it further by rotating/limiting the key duration to let say 20 minutes. You can go extreme by turning TKIP on where you get UNIQUE key per PACKET: http://wlanresearch.com/LEAPVPN.htm
PEAP is similar to LEAP for the dynamic session key part. As for the rotating key and TKIP, LEAP is far better than anything else out there. It is truly a quantum leap :-)
