Key Length
For 64 bits encryption, each key contains 10 hex digits or 5 ASCII characters. For
128 bits encryption, each key contains 26 hex digits or 13 ASCII characters.
Manual assign WEP keys
- When you select this option, the cursor appears
in the eld for Key 1. For 64-bit encryption, you are required to enter four WEP
Keys. Each Key contains exactly 10 hex digits (0~9, a~f, and A~F). For 128-bit
encryption, you are required to enter four WEP Keys. Each Key contains exactly 26
hex digits (0~9, a~f, and A~F).
Select one as your Default Key
The Default Key eld allows you specify which of the four encryption keys is to
use for transmitting data over wireless LAN. You can change the default key by
clicking on the downward arrow, selecting the number of the key you want to use,
and clicking the “Apply” button. If the access point or station with which you are
communicating uses the identical key by the same sequence, you can use any of
the keys as the default on your Network adapter.
Click the “Apply” button after you have created the encryption keys, the Wireless
Settings Utility uses asterisks to mask your keys.
64/128bits versus 40/104bits
There are two levels of WEP Encryption: 64 bits and 128 bits.
Firstly, 64 bit WEP and 40 bit WEP are the same encryption method and can
interoperate in the wireless network. This lower level of WEP encryption uses a 40
bit (10 Hex character) as a “secret key” (set by user), and a 24 bit
“Initialization Vector” (not under user control). This together makes 64 bits (40 +
24). Some vendors refer to this level of WEP as 40 bits and others refer to this
as 64 bits. Our Wireless LAN products use the term 64 bits when referring to this
lower level of encryption.
Secondly, 104 bit WEP and 128 bit WEP are the same encryption method and can
interoperate in the wireless network. This higher level of WEP encryption uses a
104 bit (26 Hex character) as a “secret key” (set by user), and a 24 bit
“Initialization Vector” (not under user control). This together makes 128 bits (104 +
24). Some vendors refer to this level of WEP as 104 bits and others refer to this as
128 bits. Our Wireless LAN products use the term 128 bits when referring to this
higher level of encryption.
