Re: WPA-PSK audit

Hello Josh,

Since the PSK is
shared among all stations on the wireless network, every user with a
workstation that has the PSK could conceivably know the PSK and share it
with anyone else.  Further, a stolen device could disclose the PSK for
the network, compromising all later data exchanges.

And all earlier data exchanged, yes?  My memory of the protocol is
fuzzy, but WPA-PSK doesn't provide perfect forward secrecy, does it?

thanks,
tim
