Have a look at this:

In simple terms, WPA-PSK is extra-strong encryption where encryption keys are automatically changed (called rekeying) and authenticated between devices after a specified period of time, or after a specified number of packets has been transmitted. This is called the rekey interval. WPA-PSK is far superior to WEP and provides stronger protection for the home/SOHO user for two reasons. The process used to generate the encryption key is very rigorous and the rekeying (or key changing) is done very quickly. This stops even the most determined hacker from gathering enough data to break the encryption.
