Configuring WPA2 (CCMP) Personal Parameters
WPA2 Personal type is use for small offices and home offices. The WPA2 Personal type provides basic level
of security that is adequate for usage in the above organizations.
Figure 3.11 WPA2 Type Screen - Personal
Configure the fields as per the following description:
WPA2 Algorithm Select the WPA2 algorithm to use:
• TKIP – Defines a ‘ wrapper ’ that goes around an existing WEP encryption
algorithm. TKIP comprises the same encryption engine and RC4 algorithm
defined for WEP. However, the key used for encryption in TKIP is 128 bits
long.
TKIP changes the key used for each packet. The key is created by mixing
together a combination of things, including a base key (called a Pairwise
Transient Key), the MAC address of the transmitting station, and the serial
number for the packet.
• CCMP (AES) – Utilizes an Advanced Encryption Standard (AES) 128-bit
key algorithm with a 48-bit initialization vector (IV) for replay detection.
The
Counter Mode (CM) component of CCMP is the algorithm providing
data privacy. The Cipher Block Chaining Message Authentication Code
(CBC-MAC) component of CCMP provides data integrity and
authentication.
• Both – Select this option to enable CB3000 to support devices that use
both TKIP and CCMP algorithms. Use this option when the number of
devices is large.
WPA2 Shared Key Enter the key (8-63 characters long) that is shared between the client and
CB3000.
