Quantum Cryptography Systems Commercially Launched

Posted by simoniker on from the i-lost-my-cat dept.

prostoalex writes "NY-based MagiQ has now started commercial shipments of its quantum cryptography systems, which it claims is the first commercially available device of its type. Apparently, 'Quantum cryptography goes a step further than electronic cryptography through its employment of a stream of photons, the quantum properties of which determine the key. The fun part is that if an intruder observes or intercepts the transmission, those properties get changed'." We've previously run stories on advances in quantum cryptography.

  1. Direct Fiber Connection? by cravey · · Score: 3, Interesting

    Yeah, but due to the nature of the the quantum portion, don't you have to have an unbroken end to end fiber connection with optical breaks for things like switching equipment? It seems that a repeater would change the polarization of the signal and kill the protocol.

    I have to say this technology is really subject to Dos style attacks. Simply overwhelm the server with false keys very much like an alphabet attack, and for those of you that scoff because of the huge numbers involved, realize the computer power of a large zombie army with todays excessive computer power.

    I don't want to say anymore because I am freaking myself out just thinking about it.
