I want the wireless adapter on my linux box to behave as an access point. I also want the wireless network to run over WPA2 for security. I also want it to serve out addresses to other devices which would join the network.

How can i achieve this?

As Chris S said, you will need to use the hostapd daemon. There is one major caveat though; your wireless card must support "Master" mode in order to act like an access point. A somewhat current compatibility list is available here: http://hostap.epitest.fi/hostapd/

Actually, if you don't like the idea of writing a configuration file for hostapd, the popular NetworkManager tool also supports managing an AP now, but this is not available through its GUI tools; it requires a manual tweak in its configuration file for mode=ap.
