Dynamic WEP Key Exchange
The AP maps a unique key that is generated with the RADIUS server. This key
expires when the wireless connection times out, disconnects or reauthentication
times out. A new WEP key is generated each time reauthentication is performed.
If this feature is enabled, it is not necessary to configure a default encryption key
in the Wireless screen. You may still configure and store keys here, but they will
not be used while Dynamic WEP is enabled.
Note: EAP-MD5 cannot be used with dynamic WEP key exchange
For added security, certificate-based authentications (EAP-TLS, EAP-TTLS and
PEAP) use dynamic keys for data encryption. They are often deployed in
corporate environments, but for public deployment, a simple user name and
password pair is more practical. The following table is a comparison of the
features of authentication types.
