Trustworthiness of measurement devices in round-robin differential-phase-shift quantum key distribution
Trustworthiness of measurement devices in round-robin differential-phase-shift quantum key distribution
Round-robin differential-phase-shift quantum key distribution (RRDPS QKD) has been proposed to raise the noise tolerability of the channel. However, in practice, the measurement device in RRDPS QKD may be imperfect. Here, we show that, with these imperfections, the security of RRDPS may be damaged by proposing two attacks for RRDPS …
