The sensitivity to losses of a recently proposed protocol of time-shift quantum key distribution with the use of decoy states is studied. An attack with discrimination of all states is analyzed. It is established that the use of decoy states ensures the security of the protocol at a high level of losses up to 11.7 dB. |
