Since a single photon source is not available for practical quantum key distribution (QKD) systems nowadays, weak coherent state are widely used in practical systems which suffers from the photon-number-splitting (PNS) attack. Fortunately, the decoy state method is proposed to defeat it, in which there is an important assumption that the signal state and decoy state is not distinguishable for Eve. However, in practical systems, this assumption is invalid in some situations, then the security of decoy state method will be compromised. Actually, a wavelength-selected PNS (WSPNS) is proposed by our group to break the security of decoy state “plug-and-play” QKD systems by exploiting the imperfection of the intensity modulator (IM) that used to generate the signal state and decoy state. Our analysis shows that Eve can use our attack to determinately distinguish the signal state and decoy state, then the security of decoy state method is broken. |
