Open
For security reasons, you should NOT set security mode to Open System because authentication and data
encryption are not performed in Open System mode.
WEP (only for legacy mode)
NOTE
Weidmüller 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.
According 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 specified in 64/128
bits, which is actually a 40/104-bit secret key with a 24-bit initialization vector. The IE-WL-BL-AP-CL 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.
