Authentication 91 ZyXEL G 220 v2 User s Guide By generating unique data encryption keys for every data packet and by creating an integrity checking mechanism MIC with TKIP and AES it is more difficult to decrypt data on a Wi Fi network than WEP and difficult for an intruder to break into the network The encryption mechanisms used for WPA 2 and WPA 2 PSK are the same The only difference between the two is that WPA 2 PSK uses a simple common password instead of user specific credentials The common password approach makes WPA 2 PSK susceptible to brute force password guessing attacks but it s still an improvement over WEP as it employs a consistent single alphanumeric password to derive a PMK which is used to generate unique temporal encryption keys This prevent all wireless devices sharing the same encryption keys a weakness of WEP User Authentication WPA and WPA2 apply IEEE 802 1x and Extensible Authentication Protocol EAP to authenticate wireless stations using an external RADIUS database WPA2 reduces the number of key exchange messages from six to four CCMP 4 way handshake and shortens the time required to connect to a network Other WPA2 authentication features that are different from WPA include key caching and pre authentication These two features are optional and may not be supported in all wireless devices Key caching allows a wireless client to store the PMK it derived through a sucessful authentication wi
