Secret key rates as functions of block size of the CV-SDI QKD protocol. The black solid line shows the performance with the distance of 5 km. The red dot-dashed line and the blue dashed line are the key rates of the protocol with distances of 10 km and 14 km, respectively. The other parameters are as in Fig. 2.
