It's an interesting proposition, and it's not using current router tech. Basically, each person who connects to a router would be separately encrypted, presumably through a shared key. The problem is that once someone can connect to a router it isn't too difficult to listen in to other people's traffic. If each connection is separately encrypted, you pretty much eliminate that possibility.

At the same time, you have the issue that people are getting raided by ATF/DHS/MOUSE at 3am, getting guns pointed at their head, having people with guns shout at them that they're child molesters, and they didn't do anything: people used their open connection to download porn, and in one case, send death threats to the vice president. I'm not entirely clear on how full encryption will prevent this. But for the time being, I'm keeping my router encrypted, no broadcast SSID, and MAC filtering. It's not totally hack-proof, but it's as close as I can easily get. I'd like to have an open router, but if I do, it's going to have all connections logged.

Let's say you use your laptop to access the internet at Starbuck's, though why you'd pay to use their service I don't know. The SSID (name) of all of their access points are called T-Mobile after their provider. Your laptop remembers the SSID, and the next time you start it up, it tries to associate with it.

So here's the hack. I create an access point named T-Mobile. Your computer boots and says "Look! There's T-Mobile! I wonder if it will be my friend?" Your laptop is now associated with my access point and is now a little bit on the vulnerable side.

First solution: firewall. Don't use the Window's firewall, get something like Zone Alarm Pro. Second, NEVER associate to ad hoc networks. Always have your card to only associate with infrastructure networks. Apparently new laptops that have built-in wireless have a button to turn the card off. They recommend using said card when networking is not in use.

Anyway, Here's The Fine Article on Slashdot that includes a link to the source story.

Important stuff if you're a Windows user who does wireless networking!
