But this uses stronger encryption scheme(WPA uses RC4 and WPA2 uses AES). This is an extension to 802.1x authentication. WPA/WPA2 -Enterprise - This uses a RADIUS Server for authentication. This uses Pre-Shared Key for authentication. WPA/WPA2-PSK - This is mainly for small offices. The standard also bring support for AES, which provides even further security benefits. WPA and WPA2 are actually are of 2 types respectively.

WPA2 closes holes in WPA, and introduces an enhanced version of TKIP, as well as CCMP.

The data being transmitted will then be converted into a radio signal. It starts when you are sending or receiving data from one end to another through Wi-Fi. You can read more about the attack at this other question. To fully understand the differences between WEP, WPA and WPA2, one should know how network security works. Whilst this makes a large improvement, vulnerabilities were found in the way that the protocol worked, allowing an attacker to break TKIP keys in about 15-20 minutes. It also improves upon the old handshake mechanism, to make it more resistant to de-auth attacks. In addition, depending on your router, performance can slow down by 30 percent or more when enabling WEP or WPA. As with WEP, WPA reduces the processing power of the network device.

WPA improves upon this, by combining RC4 with TKIP, which helps defend against the IV-based attacks found in WEP. In a performance test done by Tony Fortunato, a senior network performance specialist, WEP’s maximum transfer rate was four times lower than of that of WPA2-AES.

See this question for more details on WEP security. WEP vs WPA vs WPA2 To fully understand the differences between WEP, WPA and WPA2, one should know how network security works. Due to the severity of the break, WEP is now considered deprecated.

The attacker can then capture the initialization vectors from these re-authentication packets and use them to crack the WEP key in minutes.

Anyone with a laptop and a $20 wifi antenna can send special de-auth packets, which cause legitimate clients to re-authenticate to the AP.

WEP relies on a broken RC4 implementation and has severe flaws in various aspects of its protocol which make breaking WEP near-trivial.However, the security of the protocol does rely on making the key secure.

They don't mandate how the AP password is encrypted or hashed during storage. Wi-Fi Protected Access II (WPA2) The WPA2 security protocol increased the complexity of its predecessor (WPA) and has been the standard for network security for over a decade. The schemes you mention are protocols for securing 802.11x traffic over wireless networks. Comparing WPA vs WEP, the security benefits of WPA were significant but WPA’s own flaws quickly became apparent.
