Wi-Fi Protected Access (WPA v1 and WPA v2) Privacy for an AAA WM-AD
The WM-AD Privacy feature supports Wi-Fi Protected Access (WPA v1 and WPA v2), a security
solution that adds authentication to enhanced WEP encryption and key management.
The authentication portion of WPA for AAA is in Enterprise Mode:
Specifies 802.1X with Extensible Authentication Protocol (EAP)
Requires a RADIUS or other authentication server
Uses RADIUS protocols for authentication and key distribution
Centralizes management of user credentials
The encryption portion of WPA v1 is Temporal Key Integrity Protocol (TKIP). TKIP includes:
A per-packet key mixing function that shares a starting key between devices, and then changes their
encryption key for every packet (unicast key) or after the specified re-key time interval (broadcast
key) expires
An extended WEP key length of 256-bits
An enhanced Initialization Vector (IV) of 48 bits, instead of 24 bits, making it more difficult to
compromise
