Comment on "Quantum Key Distribution with the Blind Polarization Bases"
  We show an eavesdropping scheme, by which the eavesdropper can achieve the full information of the key against the protocol [Kye et al., PRL 95 040501 (2005)] with a probability of unity and will not be discovered by the the legitimate users, even in the case that they have the perfect single-photon source and the loseless channel.
