On the Measurement Basis Choice for the Detection of Intercept-Resend Attack towards the Transmission of GHZ States

In this paper, we investigate how to enlarge the detection probability of the security check process, because it is of utmost importance for quantum secure communication. We first describe one specific kind transmission of GHZ states, and then analyze its detection probability of intercept-resend attack. Finally, we improve the detection strategy by suggesting a better choice of measurement basis for the communicants. Our research is worth of reference when designing a quantum communication protocol.
