摘　　要：结合现有主要攻击方法,从非理想光源、非理想编解码模块和非理想探测器三个方面分析了该量子密钥分配系统的实际安全性,同时提出了四相位调制、接收单元和探测器改造等增强实际安全性的具体要求。Combing with existing main attacking methods, the paper analyzed the practical security of the Faraday-Michelson QKD system in three ways - nonideal sources, nonideal encoding and decoding modules, and nonideal detectors. Specific requirements, such as four-phase demodulation, reform of the receiver unit and detectors, were proposed to improve its practical security.
