| Abstract: | The security of quantum key distribution is based on the validity of quantum principle,then it is secure in physics.However an eavesdropper can interne in the legal users' communication without violate the physical principles.In this paper,we will give detailed discussions on some attack techniques by an eavesdropper,which including individual attack,collective attack,impersonal attack,photon-number-resolving attack and Trojan horse attack. |
