Quantum cryptography open to hacking

I can’t bring myself to be too surprised by the news that, a scant year after the first quantum cryptography network was demonstrated, someone already has a theoretical hack for it. Of course, it’s only theoretical at this stage, but that’s exactly what they said about the DRM on Blu-ray and HD-DVD – and it didn’t take long for them to be crowbarred open, either. Technology is never going to be a foolproof method for hiding secrets, because the hackers will only ever be one step behind – if not ahead. Maybe David Brin is right, and the only solution is for no one to have any secrets to steal. [Engadget]
