Wpa2 became available as early as 2004 and was officially required by 2006. Tkip is a deprecated encryption method, and apart from security concerns, its known to slow down systems that still run it. The protocol used by wpa2, based on the advanced encryption standard aes cipher along with strong message authenticity and integrity checking is significantly stronger in protection for both privacy and integrity than the rc4based tkip that is used by wpa. Unlike in wep and wpa, aes advanced encryption standard algorithms were implemented. In order to change the setting you have to go via the none option, apply it and then choose the option you want and apply that. Ways to speed up wpa2 cracking aircrackng, cowpatty. If you must choose between wep and tkip, choose tkip. The tkip protocol, which makes use of an notsecureenough rc4 cipher, was required for inclusion in all wpa certified routers. This was necessary because the breaking of wep had left wifi networks. Since im trying to do it like a pro would, i need to speed up the cracking process which is currently at 2000keyssec with crunch generating words in realtime to feed aircrackng. Network card that supports packet injection, such as an intel ign5100 based device. For every data packet, 280 trillion possible keys can be generated, using tkip. Although it comes with its own baggage, it is a much more secured protocol that supersedes that.

Aes is one of the most secure symmetric encryption algorithms. I have seen wpa tkip and wpa2 tkip, wpa aes and wpa2 aes on few access points. Data rate wont exceed 54 mbps when wep or tkip encryption. Aes is much more secure because it uses longer encryption keys and. Should you use aes or tkip for a faster wifi network. I have a few networks here that use wpa tkip and im wondering whether it makes any sense to switch them to wpa2 aes.

I dont really think that the difference between them in power draw would be noticeable, if. Most wireless routers give you the option of using tkip or aes for the key exchange. To set your router to use only wpa2, choose wpa2 with aes do not use tkip. It converts plaintext into ciphertext and comes in key lengths of 28, 192, or 256 bits. You do not need to go after the ap, but instead go after the client. Aside from that, ccmp counter cipher mode with block chaining message authentication code protocol was also introduced as a replacement to tkip still available in wpa2 as a fallback.
