network clients wanting to join the network:
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 (AESCCMP) 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.
◆ Auto — 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.
◆ Pass Phrase — The WPA Preshared Key can be input as an ASCII string (an
easy-to-remember form of letters and numbers that can include spaces) or
Hexadecimal format. (Range: 8~63 ASCII characters, or exactly 64 Hexadecimal
digits)
