◆
WPA1_WPA2
— Clients using WPA or WPA2 with an 802.1X
authentication method are accepted for authentication. The default
data encryption type is TKIP/AES.
◆
WPA Algorithms
— Selects the data encryption type to use. (Default
is determined by the Security Mode selected.)
■
TKIP
— Uses Temporal Key Integrity Protocol (TKIP) keys for
encryption. WPA specifies TKIP as the data encryption method to
replace WEP. TKIP avoids the problems of WEP static keys by
dynamically changing data encryption keys.
■
AES
— Uses Advanced Encryption Standard (AES) keys for
encryption. WPA2 uses AES Counter-Mode encryption with Cipher
Block Chaining Message Authentication Code (CBC-MAC) for
message integrity. The AES Counter-Mode/CBCMAC Protocol (AES-
CCMP) provides extremely robust data confidentiality using a 128-
bit key. Use of AES-CCMP encryption is specified as a standard
requirement for WPA2. Before implementing WPA2 in the network,
be sure client devices are upgraded to WPA2-compliant hardware.
■
TKIP/AES
— Uses either TKIP or AES keys for encryption. WPA and
WPA2 mixed modes allow both WPA and WPA2 clients to associate
to a common SSID. In mixed mode, the unicast encryption type
(TKIP or AES) is negotiated for each client.
◆
Key Renewal Interval
— Sets the time period for automatically
changing data encryption keys and redistributing them to all connected
clients. (Default: 3600 seconds)
◆
PMK Cache Period
— WPA2 provides fast roaming for authenticated
clients by retaining keys and other security information in a cache, so
that if a client roams away from an access point and then returns
reauthentication is not required. This parameter sets the time for
deleting the cached WPA2 Pairwise Master Key (PMK) security
information. (Default: 10 minutes)
◆
Pre-Authentication
— When using WPA2, pre-authentication can be
enabled that allows clients to roam to another access point and be
quickly associated without performing full 802.1X authentication.
(Default: Disabled)
