A passive scheme with a beam splitter and a photon-number-resolving (PNR)detector is proposed to verify the photon statistics of an untrusted source ina plug-and-play quantum-key-distribution system by applying a three-intensitydecoy-state protocol. The practical issues due to statistical fluctuation anddetection noise are analyzed. The simulation results show that the scheme canwork efficiently when the total number of optical pulses sent from Alice to Bobis above 10^8, and the dark count rate of the PNR detector is below 0.5counts/pulse, which is realizable with current techniques. Furthermore, wepropose a practical realization of the PNR detector with a variable opticalattenuator combined with a threshold detector.
