When to Use Static WEP
Static
Wired Equivalent Privacy
(
WEP
) is a data encryption protocol for 802.11 wireless networks. All
wireless stations and access points on the network are configured with a static 64-bit (40-bit secret key +
24-bit initialization vector (IV)) or 128-bit (104-bit secret key + 24-bit IV) Shared Key for data encryption.
R
ECOMMENDATIONS
Static WEP was designed to provide security equivalent of sending unencrypted data through an Ethernet
connection, however it has major flaws and it does not provide even this intended level of security.
Therefore, Static WEP is not recommended as a secure mode. The only time to use Static WEP is when
interoperability issues make it the only option available to you and you are not concerned with the potential
of exposing the data on your network.

When to Use IEEE 802.1x
IEEE
802.1x
is the standard for passing the Extensible Authentication Protocol (
EAP
) over an 802.11
wireless network using a protocol called EAP Encapsulation Over LANs (EAPOL). This is a newer, more
secure standard than Static WEP.
Key Management
Encryption Algorithm
User Authentication
Static
WEP
uses a fixed key that is
provided by the administrator. WEP
keys are indexed in different slots
(up to four on the Professional
Access Point).
The client devices must have the
same key indexed in the same slot
to access data on the access point.
An
RC4
stream cipher is used to
encrypt the frame body and
cyclic
redundancy checking
(CRC) of each
802.11 frame.
If you set the
Authentication Algorithm
to
Shared Key
, this protocol provides
a rudimentary form of user authenti-
cation.
However, if the A
uthentication Algo-
rithm
is set to
Open System
, no
authentication is performed.
If the algorithm is set to
Both
, only
WEP clients are authenticated.
