Measurement-device-independent quantum coin tossing

Abstract: Quantum coin tossing (QCT) is an important primitive of quantum cryptography and has received continuous interest. However, in practical QCT, Bob's detectors can be subjected to detector-side channel attacks launched by dishonest Alice, which will possibly make the protocol completely insecure. Here, we report a simple strategy of a detector-blinding attack based on a recent experiment. To remove all the detector side-channels, we present a solution of measurement-device-independent QCT (MDI-QCT). This method … Show more

“…In 2014, Ren et al proposed a novel quantum coin toss scheme in the coin toss game [Ren, Wang, Lian et al (2014)]. In 2015, Zhao et al put forward measurement-deviceindependent quantum coin toss protocol [Zhao, Yin, Wang et al (2015)]. In 2018, Abergel David proposed a quantum coin toss [Abergel (2018)].…”

“…Zhao et al [259] report using measurement-device independence [61,159] to protect quantum coin tossing against detector-side channel attacks due to Alice, who may launch a detector-blinding attack based on a recent experiment. This scheme essentially modifies the protocol of [253] to incorporate the measurement-deviceindependent method, but the authors also consider the possibility of using weak coherent pulses.…”
