- Abstract
Recently, a measurement-device-independent protocol for deterministic quantum secret sharing was proposed (Gao et al. in Sci Chin Phys Mech Astron 63(12):120311, 2020). Unfortunately, it was pointed out to be insecure against the participant attack (Yang et al. in Sci Chin Phys Mech Astron 64(6):260321, 2021). However, this participant attack strategy has an assumption that a dishonest agent has to reveal his single-photon state after other agents. Here, we give a more powerful participant attack strategy regardless of the announcement order.
