Chapter 3 - Software Configuration

Access Point

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
Selecting “TKIP” or “AES” in the WPA Encryption, this field is used as

a password to begin the encryption process. Note: 8 to 63 characters are

required.
WEP Encryption
Traditional WEP encryption is applied when “Open or Shared Key”, “Shared

Key” or “Radius with 802.1x” authentication methods are selected.

NOTE:

When “WPA” or “WPA-PSK” authentication methods are se-

lected, 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:
6-bit WEP Encryption
64-bit WEP and 40-bit WEP are the same encryption method 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.
