Radio Interface
5-39
Multicast Cipher Mode – Selects an encryption method for the
global key used for multicast and broadcast traffic, which is
supported by all wireless clients.
•
WEP: WEP is the first generation security protocol used to
encrypt data crossing the wireless medium using a fairly short
key. Communicating devices must use the same WEP key to
encrypt and decrypt radio signals. WEP has many security
flaws, and is not recommended for transmitting
highly-sensitive data.
•
TKIP: TKIP provides data encryption enhancements including
per-packet key hashing (that is, changing the encryption key
on each packet), a message integrity check, an extended
initialization vector with sequencing rules, and a re-keying
mechanism.
•
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 standard.
WPA Pre-Shared Key Type – If the WPA pre-shared-key mode is
used, all wireless clients must be configured with the same key to
communicate with the access point.
•
Hexadecimal: Enter a key as a string of 64 hexadecimal
numbers.
•
Alphanumeric: Enter a key as an easy-to-remember form of
letters and numbers. The string must be from 8 to 63
characters, which can include spaces.
