Download Free technews From viewzoft Its always only a matter of time. A little less than a year after the first quantum cryptographic network was demoed, a group of researchers at MIT have announced a working implementation of a hack thats been around in theory since 1998 but never implemented. Skirting around ol Wernie Heisenberg and that Principle of his, the team exploited quantum entanglement to read the encryption keys encoded in photon polarizations from their momentums, avoiding detection by either end -- in other words, doing what was once thought impossible by cryptographers. The system isnt perfect, however -- in this early incarnation it can only nab 40% of transmitted data before giving itself away, and more importantly, it requires the invention of a "quantum non-demolition box" before the attacker can be anywhere but the same room as the receiver, since right now both attacker and receiver need to be using the same photon detector. Sounds like that might put a damper on that whole "undetectable" thing. Still, the researchers sound upbeat -- theyre saying the work proves that no secret is truly safe. Were just wondering if theyre pushing MIT to rename their department SETEC ASTRONOMY. ( Read More )
Download Free technews From viewzoft Just over a week after a dubious duo found a way to commandeer a Mac thanks to an elusive flaw in QuickTime (of all things), Apples security police have purportedly fixed the flaw and issued an update. Apparently, the hole could be "exploited through a rigged website and let an attacker control computers running both Mac OS X and Windows," and the firm elaborated by stating that a "maliciously crafted Java applet could lead to arbitrary code execution" if users didnt apply the patch. The newest version of QuickTime now sits at 7.1.6, and reportedly "repairs the problem by performing additional checking," and interestingly enough, Apple seemingly tipped its hat to Dino Dai Zovi and the TippingPoint Zero Day Initiative for reporting the issue. So make sure you fire up that Software Update today if you havent already -- a presumably small bundle of downloadable joy should be waiting. ( Read More )
