As for mixing wpaaes and wpa2tkip, this isnt standards based, but vendors on the client side and infrastructure side support it. Because wpa and wpa2 both are vulnerable to the same attack when exchanging keys using tkip. Currenty our ssid profile is allowing mixed authentication of wpaaes, wpatkip, wpa2aes and wpa2tkip. So, contrary to what virtually every pundit is currently recommending, it is not necessary to abandon wpa in favor of wpa2. Enough with the general knowledge, its high time we got a bit mire specific, but first an answer to the question. Tkip also turned out to be insecure, so a new standard called wpa2 was created, which uses aes, or advanced encryption standard.
Tkip is a little less stronger in terms of encryption but is widely supported by many devices on the market. Wpa2 uses aes for packet encryption, whereas wpa uses tkip encryption. Wpawpa2 supports many types of authentication beyond preshared keys. Researchers has discovered several key management vulnerabilities in core wifi protected access ii wpa2 protocol that allows any attacker to hack into your wpa2 network which you through as more secured then other protocols however, wpa2 is also an old encryption mechanism which. Using the above 3 methods puts breaking into your wireless network well beyond the abilities of anyone.

Notice in the top line to the far right, airodumpng says wpa handshake. Setting it to a mode that allows both will allow older devices that dont support wpa2 to connect in wpa mode, while devices that do support wpa2 will use that instead. Later, wpa2 became an industry standard since it introduced aes encryption, which is more powerful than tkip. The choice between tkip temporal key integrity protocol and aes advanced encryption standard is a choice between old and new technologies, respectively. While wpa2 is supposed to use aes for optimal security, it can also use tkip where backward compatibility with legacy devices is needed.
When you use wpa2 with aes and tkip which you may want to do if communicating with legacy devices, you could experience slower transmit speeds. The airport extreme just says wpa2 personal, does not mention aes or tkip, but the device i am connect say wpa2 personal aes and wpa2 personal tkip how do i set the airport extreme to wpa2 personal aes or is this the default and it does not support tkip. This is now the preferred encryption method, replacing. Aes is one of the most secure symmetric encryption algorithms. Airhead community explains this is because group ciphers will always drop to the lowest cipher. Wpawpa2 is the next evolution of secure wireless network that came up after wep turned out to be insecure. Crack wpa2 with kali linux duthcode programming exercises.
This is what replaced tkip when the final wpa2 implementation was released. Beyond the technical differences between tkip and aesccmp, the practical difference for you is what hardware will support wpa2. To set your router to use only wpa2, choose wpa2 with aes do not use tkip. You will see a lot of vendors use wpa2aes, when in fact, it really should be wpaccmp. With the wpa2, we chose to go a different route with encryption. I try alot to use commview for wifi but it dosnt work with me. If it only supports wpa it will connect with wpa with tkip. Aes is the best solution if your equipment supports it, mandatory since 2006 from a wifi alliance perspective as it is more efficient and secure than tkip. Airdecap wouldnt decrypt any packets captured over my wpa2aes encrypted wireless, however wireshark would. Most routers these days use a random key code provided by the isp, its either in the manual or on a sticker on the base of the unit. Based on what ive read, it is the tkip encryption that is broken. I applied the patch, recompiled, used the exact same capture file and airdecap parameters, and it decrypted just fine.
