An Uncrackable Lock
Imagine an encrypted data chip so secure that even the greatest hackers in history would find impossible to crack. That chip is very much a reality thanks to the combined efforts of Siemens, Austrian Research Centers (ARC) and Graz University of Technology who have teamed up to create the first quantum cryptology chip for commercial use to ensure securer electronic communication.
8.5.2008 at 03:18pm - Comment by Someone_It's 'uncrackable' because it would violate laws of physic. Quantum cryptography uses single photons to negotiate a key. A hacker would need to watch them and make sure they receive as they were, which is impossible, Heisenberg said. Watching the photon you would destroy it. Then you use the negotiated key with some standard-encryption like AES or RSA, which theoretically is crackable.
