Code for Unbreakable Quantum Encryption

Posted by ryuzaki0 on from the photon-data-torpedo dept.

An anonymous reader writes "ITO is running a story on NIST's latest quantum encryption key generation. From the article: 'Raw code for "unbreakable" quantum encryption has been generated at record speed over optical fiber at NIST. The work is a step toward using conventional high-speed networks such as broadband Internet and local-area networks to transmit ultra-secure video for applications such as surveillance.'"

    All together now: "this has nothing to do with quantum computing".

    This system exploits quantum mechanics to detect if someone is interecepting and retransmitting the signal. That's why it's called Quantum KEY Distribution. There's nothing "quantum" about the encryption itself. It is also of limited use since it requires an unbroken fiber-optic connection between the two devices.
