A new encryption system, which its creators say is unbreakable, got its first test run Wednesday in Vienna, scientists from the European Union project SECOQC announced.
digg user kinthiri explains:
Quantum cryptography is unbreakable because if any 3rd party views it that does not have the credentials and is not the intended recipient, the simple viewing of the encrypted data by that third party changes that data such that even the intended recipient can’t decrypt it. Thus they know that there is a 3rd party viewing the stream. Effectively the data self destructs if anyone attempts to intercept it or decrypt it. This is not a new phenomenon.
What is new is that its being used commercially. It had previously been used experimentally by the military in association with researchers, but this is the first time its been brought to life outside test environments and is available commercially.
The nature of quantum mechanics makes this truly unbreakable. You couldn’t even factor this using your own quantum computer, if you could even get one with enough qbits.
