Cipher Suites Select the cipher you want to use from the drop-down menu:
• 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 reused 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.
When the authentication algorithm is set to “Both”, 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. Enter a string of
at least 8 characters to a maximum of 63 characters.
WPA-PSK
Wi-Fi Protected Access (WPA) with Pre-Shared Key (PSK) is a Wi-Fi Alliance subset of
IEEE 802.11i, which includes Temporal Key Integrity Protocol (TKIP), Advanced
Encryption Algorithm (AES), and Counter mode/CBC-MAC Protocol (CCMP)
mechanisms. PSK employs a pre-shared key. This is used for an initial check of credentials
only. If you selected “WPA-PSK” Security Mode, provide the following:
