Abstract

In the paper on the basis of methods of the quantum information theory the most powerful photon number splitting attack (the attack with replacement of the quantum channel with losses on ideal channel) on the protocol of quantum key distribution with six states is analyzed. It is shown that security of the protocol with six states to photon number splitting attack is higher for some percent, than security of the BB84 protocol, at any values of mean photon number in an impulse and transmission efficiency of the channel. It is also shown that, as well as for the BB84 protocol, security decreases both at increase in mean photon number, and at decrease in transmission efficiency.
