I have seen wpa tkip and wpa2 tkip, wpa aes and wpa2 aes on few access points. Tkip also turned out to be insecure, so a new standard called wpa2 was created, which uses aes, or advanced encryption standard. As pbkdf2 is a slow hashing method, it will be costly to crack fairly complex. If you use these encryption methods for example, wep, wpa tkip, your data rate will drop to 54 mbps. To set your router to use only wpa2, choose wpa2 with aes do not use tkip. Everyone should update their devices to prevent the attack.

There was a great comment after that blog askingstating how preauthentication works with wpa. Wpa uses the tkip temporal key integrity protocol to create encryption keys from passphrases supplied by the administrator, coupled with ssid service set identifier codes of wireless networks. It converts plaintext into ciphertext and comes in key lengths of 28, 192, or 256 bits. This article seems to have carried forward some of the misinformation. Due to serious security weaknesses, the wep and wpa tkip encryption methods are deprecated and strongly discouraged.

The problem im having is that our secure network users are starting to complain about the speed of the network versus the open network. Well the maximum length is 63, but of course the more characters the more secure.
Wpa2 uses tkip aes algorithms to encrypt, which is a lot safer though not completely safe than wep, though that should have negligible effect on the actual speed. Aes is one of the most secure symmetric encryption algorithms. Should you use aes or tkip for a faster wifi network. If you must choose between wep and tkip, choose tkip. Wifi security types explained there are many types of. How to hack any wifi wpawpa2 tkipaes passwords with. These files are generally used to speed up the cracking process. Tkip is actually an old encryption protocol introduced with wpa to replace. In this article, we will explain what aes and tkip are and suggest which. 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. Use these modes only if necessary to support legacy wifi devices that dont support wpa2 aes and cant be upgraded to support wpa2 aes. Wep was deeply flawed and we fixed a few things with wpa such as upgrading from rc4 to tkip.
Cracking wpa with a word list is kinda pointless, you need to look at using a gpu to crack the code as its faster, and use more random key combinations ie hanyr3bn28bnann21n3a and so on. In terms of security, aes is much more secure than tkip. Robert mcmillan from idg news service reports that two japanese scientist from the hiroshima and kobe universities found a way to crack the wpa encryption system in. This was necessary because the breaking of wep had left wifi networks. The wpa psk tkip and wpa2psk aes cracking module by decision group allows recovery of wappsk tkip and wpa2psk aes passwordkey. The exact impact greatly depends on the processing power of the network device, it can vary from 5% to 30% of the maximum throughput. In essence, tkip is deprecated and no longer considered secure, much like wep encryption. When the original tkip crack came out last year, there was a lot of misinformation about wpa being insecure and wpa2 being completely secure. As far as switching is concerned, you definitely should as wpa2aes is required to get 802.
