I am aware that WEP has been broken, and I have read various White Papers on how it was broken but I fail to understand how the encryption keys are used.

Im hoping someone out there knows more about this than my limited knowledge.

If dynamic WEP keys are used (rotating every 15mins) rather than using static WEP keys, would this be a secure solution?

In addition, does anyone know of any security flaws with Kerberos encryption and authentication over a Wireless network?

I would prefer token authentication across a secure tunnel, but hey, Im just a lowlife security pleb!!!
