Hardware hackers defeat quantum crypto • The Register
September 1, 2010 § Leave a comment
Security researchers using hardware hacking techniques have unearthed generic flaws in supposedly ultra-secure quantum cryptography systems.
The security of quantum cryptography hinges on using the fundamental properties of quantum physics for quantum key exchange. Any attempts to monitor this exchange would inevitably be detected as increased noise on the line and an abandoned data exchange. That principle remains solid and the attack, like others before it, relies on exploiting implementation flaws.
