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."

Boycott Roland Piquepaille Stories

[goldspider]

Yes, offtopic, I know. Moving on.

There are a lot of us here who object to Roland Piquepaille's well-documented practice of using Slashdot to direct readers to his site and thereby generate ad revenue for himself.

Roland Piquepaille contributes none of his own work (it's ALL derivative of others' efforts), and Slashdot is more than willing to sell their readers out to this character.

So the next time a Roland Piquepaille-submitted story comes up, don't read it. Don't post replies. Don't even acknowledge that the story is there.

It's time we send Slashdot the message that we don't like being taken advantage of in this manner.

Why?

I don't see this as being really practical for security. So you've got all of this quantum-encrypted video which is infinitely better than an SSH-encrypted stream and you're feeling pretty smug about how unbreakable it is. Meanwhile, the janitor has planted a bug under your desk and is eavesdropping on everything you say. Or someone else hid a pinhole camera in a plant and is recording it all.

While I applaud the research and find the technology cool, I don't think a lack of decent encryption technology is the weakest link with regards to security.
