Secure Video Conferencing via Quantum Cryptography

Roland Piquepaille writes "If you use a webcam to talk with your mom, this tool is not for you. But if you're working for a company and that you have to routinely discuss about sensitive future projects or the possible acquisition of another company, you need more security, and this new video conferencing system based on quantum cryptography is a tool you need. According to this article from Nature, researchers from Toshiba have developed a system which can generate 100 quantum 'keys' every second, fast enough to protect every frame in a video exchange. This technology, which today is working over a distance of about 120 kilometers, could become commercially available within two years at an initial cost of $20,000. This overview contains more details and references."

The Star Wars Kid could have used this

Maybe this "tool" isn't for having a chat with mom, but if you plan on making a Star Wars like lightsaber duel with a broom, make sure to use this.

Not only the company

[Anonymous Coward]

But you can cheat on your spouse as well!!

Not that the internet has such nefarious uses!

ah..

[Keruo]

video conferencing.. the politically correct way to say, streaming porn

What happened to Oscar?

[Vorondil28]

From the article:
Single photons do not split, so if the hacker (Eve) measures the photons on the fibre, they will not reach the intended recipient (Bob).

IIRC, "Oscar" was the traditional (wo)man-in-the-middle. If this new "Eve" is hot, she can have all the photons she wants.

Potential problem

Quantum cryptography is neat, to be sure, but what happens if the cat dies?
