Advanced Encryption Standard (AES)
AES has been designated by the National Institute of Standards
and Technology as the successor to the Data Encryption
Standard (DES) encryption algorithm, and will be used by the
U.S. government for encrypting all sensitive, nonclassified
information. Because of its strength, and resistance to attack,
AES is also being incorporated as part of the 802.11 security
standard.
The bridge radio band uses 128-bit static AES keys (hexadecimal
or alphanumeric strings) that are configured for each link p air in
the wireless bridge network. For a Slave bridge unit, only one
encryption key needs to be defined. A Master bridge allows a
different key to be defined for each wireless bridge link in the
network.
