Open
For security reasons, it is highly recommended that the security mode should be set to the options
other than Open System. When the security mode is set to Open System, no authentication or data
encryption will be performed.
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-4121 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.
