MIT Demos Wi-Fi That's So High-Tech It Doesn't Need a Password (mic.com)

An anonymous reader shares an article on MIC: Researchers at the Massachusetts Institute of Technology want to change how we connect to Wi-Fi. To avoid the cumbersome network login process, a team has come up with a way to grant computers access to a Wi-Fi network based on their proximity to a router. Applied practically, that means you could walk into a cafe and your device would automatically connect to a network -- no annoying password necessary. The same could be true for a home network. When your friends come over, they could immediately be granted access to your Wi-Fi. The paper (PDF), sadly, doesn't offer details on the security aspect. Security researchers advise that one should be careful when connecting to a public Wi-Fi. Say you forget to turn off Wi-Fi on your device, and you walk into a cafe. Your phone will automatically establish a connection with this supposed network. If the network is compromised, plenty of devices will be exposed to attack.

      It says 97% accuracy within the building and 10 inch resolution so if that 3% failure rate was double or even triple then that's still accurate to less than 3 feet which would be plenty accurate enough. Honestly, I'm just guessing and 97% accuracy is almost meaningless in this context. It would be much better to say "accurate to 10 inches +/- 5 inches" or something along those lines or "works reliably 97% of the time and 3% of the time someone inside the building can't connect" which would be the other likely failure mode.

  15. Public Hotspot software by craighansen · · Score: 1

    This kind of application desperately needs to include hotspot software that does a VPN over SSL or TLS (https security layer, relying on PKI). An ideal platform for doing this would be for email providers to add VPN for internet access alongside the SSL/TLS links they already operate for IMAP/POP3/SMTP, as it provides for some level of user authentication and traceability. There's also existing standalone VPN hotspots, but incorporating VPN into email would help make VPN ubiquitous.

    I'm guessing this is an April Fool's story, because even if the signal is encrypted, there's no authentication factor to it, all you have to do is get in range. Furthermore, range boosters become a serious weakness; slip a tiny one in a corner or something, and BOOM! Instant security breach. I will say though, this was a pretty good one - not nearly so obvious as previous years.

      I think I'm wasting a post due to the April 1 chaos today, but everyone seems to be missing the point here. This is real, and it's not just an open network. And it's not vulnerable to range boosters - it's fundamentally undefeatable range-based authentication. The system uses time-of-flight of the signal to measure the distance from access point to user much like radar. Some wifi hardware already does this, but doesn't use that information for authentication purposes. For example, Ubiquiti's AirOS devices provide an actual range measurement but with much lower resolution since they are intended for long-range links. This is just an improvement in accuracy combined with the use of measured range data for authentication. It's very clever.

    This does nothing for in-band security. Basically anyone in the same cafe or router range could sniff and hack you as much as with passwords. The main thing it does is Geofence the WiFi router. So you must be in a given physical proximity to get into the router at all - even being in the street outside would be blocked. However emissions still occur so you could still promiscuously intercept any WiFi connected device. You just can't perform a man-in-the-middle or other crack without being inside the GeoFence.
