4-16 Chapter 4: Configuration

WPA Encryption

When “WPA-PSK” authentication method is used, the newly proposed TKIP

(Temporal Key Integrity Protocol) or AES encryption schemes are applied.

WPA Pre-Shared Key

Select “TKIP” or “AES” in the WPA Encryption, this eld is used as a password to

begin the encryption process. 8 to 63 characters are required.

WEP Encryption

When “Open or Shared Key”, “Shared Key” or “Radius with 802.1x” authentication

methods are selected, traditional WEP encrption is applied.

When “WPA” or “WPA-PSK” authentication methods are selected, you still

can set WEP encryption for those clients that do not support WPA/WPA-PSK.

Please note that Key Index for WEP key is limited to 2 or 3 when both WPA and

WEP encryption are supported at the same time.

64/128-bit versus 40/104-bit

The following section explains low-level (64-bit) and high-level (128-bit) WEP

Encryption schemes:

64-bit WEP Encryption

64-bit WEP and 40-bit WEP are the same encryption methods and can

interoperate in a wireless network. This level of WEP encryption uses a 40-bit (10

Hex character) encryption scheme as a secret key, which is set by the user, and a

24-bit “Initialization Vector” scheme, which is not under user control.

Together these two schemes make a 64-bit (40 + 24) encryption scheme. Some

vendors refer to this level of WEP as 40-bit and others refer to this as 64-bit. ASUS

WLAN products use the term 64-bit when referring to this lower level of encryption.

128-bit WEP Encryption

104-bit WEP and 128-bit WEP are the same encryption method and can

interoperate on a wireless network. This level of WEP encryption uses a 104-bit

(26 Hex character) encryption scheme as a secret key which is set by the user,

and a 24-bit “Initialization Vector”, which is not under user control.

Together these two schemes make a 128-bit (104 + 24) encryption scheme. Some

vendors refer to this level of WEP as 104-bit and others refer to this as 128-bit.

ASUS WLAN products use the term 128-bit when referring to this higher level of

encryption.
