Moxa Technologies AirWorks AWK-1137C User Manual

AirWorks AWK-1137C Web Console Configuration
3-19
Open
For security reasons, you should NOT set security mode to Open System, since authentication and data
encryption are NOT performed in Open System mode.
WEP (only for legacy mode)
NOTE
Moxa includes
WEP security mode only for legacy purposes. WEP is highly insecure and is considered fully
deprecated by the Wi
-Fi alliance. We do not recommend the use of WEP security under any circumstances.
Accord
ing to the IEEE 802.11
standard, WEP can be used for
authentication and data encryption
to maintain
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 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 64/128 bits,
which is actually a 40/104-bit secret key with a 24-bit initialization vector. The AWK-1137C 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 types, 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.
