摘要

Quantum cryptography is the first application of quantum physics at the single photon level. The most important application of quantum cryptography is Quantum Key Distribution (QKD). One of the biggest problems of QKD implementation is enormous number of possible attacks, which puts out specific need for more refined simulation strategies in bridging the gap between theoretic models and their implementation. In this work we have introduced generalized optical architecture which can provide various solutions of some actual problems for two mostly used QKD protocols: BB84 and B92 protocols. Simulations, which included the influence of optical losses over a quantum channel with concrete realistic lengths, have confirmed validity and high level of provable security of the proposed generalized QKD authentication architecture. Due to simplicity of the proposed architecture and obtained QKD B92 protocol communication efficiency, we believe that it can be implemented, solving out some of the most relevant implementation problems which are common for both QKD protocols.
