Field Description
Cipher Suites Select the cipher you want to use from the list:
• TKIP
• CCMP (AES)
• Both
Temporal Key Integrity Protocol (TKIP) is the default.
TKIP provides a more secure encryption solution than WEP keys. The TKIP
process more frequently changes the encryption key used and better
ensures that the same key will not be re-used to encrypt data (a weakness
of WEP). TKIP uses a 128-bit “temporal key” shared by clients and access
points. The temporal key is combined with the client's MAC address and a
16-octet initialization vector to produce the key that will encrypt the data. This
ensures that each client station uses a different key to encrypt data. TKIP
uses RC4 to perform the encryption, which is the same as WEP. But TKIP
changes temporal keys every 10,000 packets and distributes them, thereby
greatly improving the security of the network.
Counter mode/CBC-MAC Protocol (CCMP) is an encryption method for
IEEE 802.11i that uses the Advanced Encryption Algorithm (AES). It uses
a CCM combined with Cipher Block Chaining Counter mode (CBC-CTR) and
Cipher Block Chaining Message Authentication Code (CBC-MAC) for
encryption and message integrity.
Both is where both TKIP and AES clients can associate with the access
point. WPA clients must have one of the following to be able to associate
with the AP:
• A valid TKIP key
• A valid CCMP (AES) key
Clients not configured to use WPA-PSK will not be able to associate with AP.
Key The
Pre-shared Key
is the shared secret key for WPA-PSK. Type a string
of at least 8 characters to a maximum of 63 characters.
