It has been said that quantum cryptography in general o ers a secure solution to the problem of key enhancement. This means that two parties who already share a small secret key, ...

In this work, we investigate secret key generation from channel states. We point out, by means of a packet-delaybased attack, that observing its own channel states is not the only ...

Secret-key agreement between two parties Alice and Bob, connected by an insecure channel, can be realized in an informationtheoretic sense if the parties share many independent pai...
