Description
TKIP or AES is used depending on the capability of the other station.
AES (Advanced Encryption Standard):
Strong symmetrical block encryption method based on the Rijndael algorithm that
further improves the functions of TKIP.
TKIP (Temporal Key Integrity Protocol): A symmetrical encryption method with the
RC4 algorithm (Ron's
Code 4). In contrast to the weak WEP encryption, TKIP uses changing keys de‐
rived from a main key.
