Security Parameters
BreezeNET B can support encryption of authentication messages
and/or data frames using one of two encryption standards:
 WEP Wireless Equivalent Privacy algorithm. WEP is defined in the
IEEE 802.11 Wireless LAN standard and is based on the RSA’s RC4
encryption algorithm.
 AES Advanced Encryption Standard. AES is defined by the National
Institute of Standards and Technology (NIST) and is based on
Rijndael block cipher.
The following parameters are available through the Security Parameters
menu (in certain units some or all of the security options may not be
available):
Authentication Algorithm
The Authentication Algorithm option determines the operation mode of
the selected unit. The two following options are available:
 Open System: An RB configured to Open System can only associate
with a BU also configured to Open System. In this case, the
authentication encryption algorithm is not used.
 Shared Key: The authentication messages are encrypted. An RB
configured to use a Shared Key can only be authenticated by a BU
configured to use a Shared Key, provided the applicable Key (which
means both the key number and its content) in the BU is identical
to the key selected as the Default Key in the RB.
The default is Open System.
NOTE
The Shared Key option cannot be selected before at least one Key is defined. In the RB,
a Default Key that refers to a valid Key must be selected.
The BU and the RB it serves should be configured to the same Authentication Algorithm
option.
