Аннотация:The SARG04 protocol is aimed at the improvement of the robustness of the main protocols in quantum cryptography (primarily, BB84 and B92) against the PNS attack in the case of the application of weak coherent pulses instead of the one-particle signals. An optimal attack of eavesdropper on the transmitted key is explicitly constructed for arbitrary angles between the basis states. A critical error up to which the key distribution is possible and the length of the final key are determined.
