We performed theoretical analysis of a sidebandsbased quantum cryptography system with two types of detectors: an avalanche photodiode and a superconducting photon counter. The influence of detector parameters on eavesdropper “Interceptresend” attack efficiency was investigated.

Keywords: quantum cryptography, interceptresend, avalanche photodiodes, superconducting single photon detectors.
