This problem can be solved with the help of: classical information-theoretic schemes (requires channel with noise; efficiency is very low, 1-5 %), classical public-key cryptography schemes (Diffie-Hellman scheme, digital envelope scheme; it has computational security), classical computationally secure symmetric-key cryptographic schemes (requires a pre-installed key on both sides and can be used only as scheme for increase in key size but not as key distribution scheme), quantum key distribution (provides information-theoretic security; it can also be used as a scheme for increase in key length), Trusted Couriers Key Distribution (it has a high price and is dependent on the human factor) (SECOQC .
Using such a scheme would allow for the first demonstration of global quantum key distribution," the physicists note in their proposal.
