Comment on “Proactive quantum secret sharing”



In the paper, Qin and Dai (Quantum Inf Process 14:4237–4244, 2015) proposed a proactive quantum secret sharing scheme. We study the security of the proposed scheme and find that it is not secure. In the distribution phase of the proposed scheme, two dishonest participants may collaborate to eavesdrop the secret of the dealer without introducing any error.
