Putting it simply, WPA's TKIP is/was an interim measure to mitigate the poor key management of RC4 in WEP. It is not expected to be necessary with WPA2's AES-CCMP due to the higher confidence in that cryptosystem.

Hello, Lately I'm reading more about upcoming standards for wireless networks WPA & WPA II. I understand the difference, but what seems to be interesting is that in some articles the author says that in WPA II., when used AES the TKIP will be NOT in use, i.e. the base key will be the same, with an IV of 2xWEP's (ie. 48 bits). Is that true or do you have indication that even with such a strong block cipher such as AES the Temporary Key Integrity Protocol will be in use?
