WEP
According to the IEEE802.11 standard, WEP can be used for authentication and data encryption
(confidentiality).
Shared
(or
Shared Key
) authentication type is used if WEP authentication and
data encryption are both needed. Normally,
Open
(or
Open System
) authentication type is often
used when WEP data encryption is run with authentication.
When WEP is enabled as a security mode, the length of a key (so-called WEP seed) can be
specified as 64/128 bits, which is actually a 40/104-bit secret key with a 24-bit initialization vector.
The AWK-3121 provides 4 entities of WEP key settings that can be selected to use with
Key index
.
The selected key setting specifies the key to be used as a
send-key
for encrypting traffic from the
AP side to the wireless client side. All 4 WEP keys are used as
receive-keys
to decrypt traffic from
the wireless client side to the AP side.
The WEP key can be presented in two
Key type
, HEX and ASCII. Each ASCII character has 8 bits,
so a 40-bit (or 64-bit) WEP key contains 5 characters, and a 104-bit (or 128-bit) key has 13
characters. In hex, each character uses 4 bits, so a 40-bit key has 10 hex characters, and a 128-bit
key has 26 characters.
