(color online) The secret key rate of the scheme against the collective attacks. The curve at the left-most position represents the secret key rate of the GMCS QKD based on the binary random basis choice. Then from left to right, the curves represent the secret key rates of our proposed scheme with the parameters k = 0.8, 0.7, 0.6, and 0.5, respectively. Meanwhile, other parameters of the simulation are V_A = 30, ε = 0.01, η = 0.6, V_el = 0.01, and β = 0.9.
