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.

    New encryption tools are cool, but they only secure the network. The end-terminals (and end-users) are still insecure. Holes in the OS, clicking on the wrong email, etc. can compromise one of the machines. And if either party likes chocolate, then we know that we can get the keys to crypto just by offering a tasty morsel.

    Security is only as strong as its weakest link. This invention ensures that the network is not the weakest link. Its a step in the right direction, but other components are still pretty vulnerable.

    perhaps Roland should spend his time and get a proper job (or perhaps nobody will employ him) and actually contribute something new to the internet instead of just leeching from others hard work.

  3. Boycott Roland Piquepaille Stories by goldspider · · Score: 5, Insightful

    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.

      I keep seeing the same sort of responses to Roland's stories, and have finally begun to wonder: why doesn't Slashdot stop posting his stories? Will someone at Slashdot address the readers' concerns? It is about time that an official answer came from Slashdot central about their relationship with Roland. I find it hard to believe that each and every story of his gets accepted, while the rest of us have a much less success rate.

  4. Why? by nacturation · · Score: 5, Insightful

    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.

    While that sounds all fine and dandy, if I understand this technology, it is not wireless. I am sure that the military could come up with some amazingly devious ideas with this, but I do not think this would be one. How could you transmit a stream of photons bearing the encryption to a remote location out of line of sight without some type of optical cable and maintain an error rate of around 9%? I am sure they have some other shit worked up for that!!!
