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
A Message Integrity Check or Code (MIC), an additional 8-byte code that is inserted before the
●
standard WEP 4-byte Integrity Check Value (ICV). These integrity codes are used to calculate and
compare, between sender and receiver, the value of all bits in a message, which ensures that the
message has not been tampered with.
