Abstract
In a recent paper (Du and Bao in Opt. Commun. 308:159, 2013), a scheme of multiparty quantum secret sharing based on the phase shift operations was presented. We study the security of this scheme and find that it is not secure for dishonest participants, who can illegally elicit all of the dealer’s secret message without any error.
