摘要：

We provide an asymmetrical quantum key distribution protocol based on the correlations of EPR pairs. It is a variant of the modified Lo-Chau protocol where the EPR pair is not in the state Phi(+) but is in one of the four states {Phi(+/-),Psi(+/-)}. The two sides communicating with each other are not equal in the process of establishing the key. A public key system can be built on the protocol. It differs from classical public key system in that there are three keys: the public key, the secret key and the real key.
