WPA is slightly newer, and only takes a couple of minutes to crack.

#Wps vs wep vs wpa attacks crack#

I can't explain the actual algorithims very well, but WEP is an older, less complicated algorithim that takes less time to crack (under 20 seconds by some reports). As long as you use a good passphrase, both WPA and WPA2 can safely be used. The real key with either is to select a LONG (26+ digits) passphrase with letters, numbers, and symbols. While WPA2 is recommended, WPA is often used for compatability reasons (XP SP2 didn't support WPA2 for example). Since RC4 is significantly faster than AES, WPA is quicker to brute force. The only viable attacks against WPA/WPA2 is brute-force. While WEP is "broken" and only takes about 30 seconds to crack, WPA and WPA2 are both still very secure. Additionally, some of the key managemet and integrity checking was enhanced, but fundamentally it works similar to WPA. All of this is provided by the Temporal Key Integrity Protocol (TKIP). To mitigate some of the attacks presented against WEP, WPA periodically exchanges the keys for new ones, as well as providing integrity checks to stop the replaying of old packets. The pre-shared key (PSK) is only used during authentication to help establish a unique encryption key for each client to use. WPA still uses RC4 to maintain compatibility with legacy hardware (with a firmware upgrade), but has a corrected implementation. Since there is no replay protection, an attacker.can collect an encrypted packet and blindly rebroadcast it to solicit more traffic (the ARP injection attack). Due to a weakness in the way they implemented the RC4 encryption, and the static encryption key, you can trivially reverse the key once you have enough packets. Everyone on the AP uses the same key and it never changes. With WEP, the encryption key Is directly used to encrypt packets. Rule #6: Homework / Educational Questions must display effort.
