Command Line Interface

TKIP defends against attacks on WEP in which the unencrypted initialization vector in encrypted packets is used to calculate the WEP key. TKIP changes the encryption key on each packet, and rotates not just the unicast keys, but the broadcast keys as well. TKIP is a replacement for WEP that removes the predictability that intruders relied on to determine the WEP key.

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.
