  • The nose knows... how to let quadriplegics move and speak (video)

    We've seen quadriplegic transportation directed by brainwaves, speech and even the occasional Wiimote, but your best bet might be to follow your nose. Israeli nasal researchers at the Weizmann Institute of Science unveiled a "sniff controller" this week, that measures nasal pressure to control a wheelchair joystick with surprising precision (see a video after the break) and a specially-developed typing interface. The latter is likely the more important advancement, as Discover heartwarmingly reports at the source link, by giving patients with locked-in syndrome (a la The Diving Bell and the Butterfly) the long-lost ability to speak. Best of all, the technology is inexpensive compared to alternatives on the market; while a Stephen Hawking-esque eye-tracking system can cost tens of thousands of dollars, Weizmann scholars reportedly pieced the prototype together for $358. The device is already being considered for public availability by the institute's technology transfer company, Yeda R&D -- find out just how it works in the full study at our more coverage link.

  • 3G GSM encryption cracked in less than two hours

    Looks like all that GSM code-cracking is progressing faster than we thought. Soon after the discovery of the 64-bit A5/1 GSM encryption flaw last month, the geniuses at Israel's Weizmann Institute of Science went ahead and cracked the KASUMI system -- a 128-bit A5/3 algorithm implemented across 3G networks -- in less than two hours. If you must know, the method applied is dubbed 'related-key sandwich attack' where multiple values of known differentials are processed through the first seven rounds of KASUMI, then using resulting quartets that are identified sharing key differences, subkey materials can be obtained in round eight to build up the 128-bit key. Sure, it's hardly snooping-on-the-go at this speed, but worryingly this was only an 'unoptimized implementation... on a single PC.' At the same time, the paper condemns the presumably red-faced GSM Association for moving from MISTY -- a more computationally-expensive but much stronger predecessor algorithm -- to KASUMI. Guess we'll just have to stick with Skype.
