best security for ad-hoc network

Archived from groups: (More info?)

I've read some articles which say that WPA-PSK is the best security for
wireless, but this seems to be available only for Infrastructure mode
networks. As soon as I select ad-hoc as the type of network, WPA-PSK
authentication gets changed to WPA-None.

What does WPA-None mean?

Is this setup (authentication=WPA-None, encryption=TKIP) at all secure.

The other thing I've read is that for a home-adhoc network, WEP encryption
with OPEN authentication is "OK", meaning not great but better than nothing,
in that it won't stop a hacker but might stop less-computer-literate
neighbours.
But how does WEP/OPEN compare with WPA-None/TKIP ??

ok - thanks,
BUT what am I losing going from WPA-PSK to WPA-None for authentication when
I change from infrastructure to adhoc?

and is WPA-None/TPIK better than OPEN/WEP for an adhoc network?

WPA-AES using a radius server is better security since you then don't use a
pre shared key.
But for most home users, setting up a radius server is not an option.
WPA-PSK with a pre shared key more than ~20 characters should be more secure
than WEP.
preferebly using AES.
With WPA in infrastructure mode, the AP will provide you the key to
encrypt/decrypt data, you can also on most AP set the timout interval when
to renew the key.
With WPA-None, there is no 802.1x authenction, the key used to encrypt /
decrypt is just a hash of the SSID and the password.
To me using WPA-None / TKIP isn't much better than WEP. (since both
encrypt/decrypt using RC4 and the key is static)
Using WPA-None and AES should increase the security but still the key is
static.

well that's my two cents
