Behind the First Secure Quantum Crypto Network
schliz writes "Researchers behind the world's largest quantum encrypted network said the technology could secure business networks inside six years. The prototype Quantum Key Distribution network was built by the Secure Communication Based On Quantum Cryptography (SECOQC) group last year. It is described in a journal paper published by the Institute of Physics this week, which includes details on how it is based on the trusted-repeater paradigm."
... what's the point of this network? The weakness of current crypto isn't that someone will break it to decrypt in feasible time, but rather what happens outside of the crypto itself. No perfectly secure quantum network can stop worms or social engineering attacks, and as far as cryptographic algorithms themselves go, AES-256 and RSA-3072 is strong enough.
Now, if suddenly everybody had a quantum computer that could break RSA in polytime, there might be a point to this, but they don't, so there isn't - not that I can see.
