Cryptanalysis of a semi-quantum secret sharing scheme based on Bell states
Abstract
In the paper [Mod. Phys. Lett. B31 (2017) 1750150], Yin et al. proposed a semi-quantum secret sharing scheme by using Bell states. We find that the proposed scheme cannot finish the quantum secret sharing task. In addition, we also find that the proposed scheme has a security loophole, that is, it will not be detected that the dishonest participant, Charlie attacks on the quantum channel.
